Thank you Mossman for this complete tutorial. I have close to zero mechanical skills but I am alright at “follow the leader” so I was able to complete this project successfully. Replacing other components while they are more accessible was time and money well spent.
Y our vidioes on the v6 intake are the best on the internet I loved the indepth step by step way you done them very helpful.keep up the good work thanks.
Excellent and outstanding videos. I'm half way. Everything is disassembled, inspected and cleaned. Now ready for installation of new parts. Thanks for the pointers and taking the time and effort to make these videos, .
' 99 Sonoma 4x4 etended cab with the exact same mileage as this one you did. Put it back together (blown intake gasket) with not one issue. runs great. I wonder what a shop would charge for this job? After Auto Zone points, $16 for Felpro gasket kit with a tube of sealer that came with it...a can of Brake Clean and a gallon of Dex Cool. Changed the oil but it was still fine. Leak went to the outside. Did this job for around 50 bucks. Thanks again for the little pointers ya don't expect until ya do the job.
That's what my neighbor said about me vs a shop. He know how thorough I am. It pays in the long run for a few minutes of PM. I clean every bolt thread and every part before reassembly. I shoot a little paint on brackets and what not before they go back on. Truck has always done me right and it's almost 20 years old in great shape from doing the little things like corrosion control. NW Indiana. Salt land here. I work for Ford.... ah hahaha
Yup, nobody will care more about your rig than you. This truck was in really good shape. Would have been a good V8 swap truck :) Sold it to one of my cousins. Last time we talked it was running great.
I just purchased an '02 s10 with an intake gasket issue. After watching these 5 video's I have all the confidence in the world to tackle the job myself. Thanks for taking the time to put this together!! Cheers!
+mossman381 just finished and everything was great for a few days and today she pushed a p0171 code. Lean fuel found in bank one. Time to start troubleshooting! Could be a vacuum leak, o2 sensor, fuel pressure regulator (which I replaced while in there).
Most complicated vehicle repair job I've done. Your videos are a great tutorial and inspired me to tackle the repair. Runs great. Thanks for posting and saving me $$$.
I watched your videos like it was my favorite movie. I think I blinked not one time. Very interesting, and straight to the point. I have a 98 GMC Safari van that I had to constantly refill with radiator fluid, and was smelling it when I turned on my heater. I knew exactly what the problem was, but don't have the time, nor the tools to do what you did. When you mentioned that someone must have used radiator stop leak, I laughed because that's exactly what I put in my radiator, but it worked. I'm not sure how long it will last though. Great video man, and like other responses, thanks for putting in the time and effort to make it wonderful.
just finished watching your videos. just a top notch job. my blazer has over 275,000 miles now its taken me everywhere and i have learned to do most of the work myself. tackling the rest of my gasket replacement tomorrow and feel way more confident now. wonderful job! thanks so much!
I have a 96 Astro van where the intake leaked so bad and it all went into my oil. After watching your video I'm confident that I can do the job thanks to all of your detailed video. Thank you from Chevy4x4
Great detail thank you. I have one in the shop that was tore down by the owner and they couldn't get it back together, I used these videos to remember how these go back together, THANK YOU AGAIN...
Thanks for posting the video; I had to change the intake gasket on my 2000 S-10 and used your video as a guide. I didn't replace as much stuff on the engine as you did. I only replaced the intake gasket since that was all I was having problems with. First time I tore down an engine this far on my own and it was an immense help to have something to go by. Took the laptop out to the garage and replayed the video as I worked. Happened to notice when you were backing your S-10 out of the shed that you are a fellow Wisconsinite.
mossman381 What helped the most is your mentioning the socket size and pointing out hidden bolts. The torque sequence for the lower intake manifold was a little fuzzy but with a quick search I found this www.fixya.com/cars/t9359670-2000_chevy_v_6_4_3_torque_sequence
Couple thangs. One very awesome video series, well explained in step by step fashion. I have '02 S10 LS 4WD 4.3L V6 and vehicle will not currently pass Northern VA emission inspection due to Check Engine Light 171 & 173 error codes, System Too Lean. I was ready to replace all vacuum lines and discovered that GM Dex Cool eats up intake gaskets and causes orange lumpy rust globs to form in the coolant. SIDE NOTE: Literally took 2x 5-gallon buckets full (10 gallons) just to flush the heater core as it was not working at all in the colder months. Had about 1/4-1/2 a cup of the lumpy rust globs got flushed out as well. GM had a Class Action lawsuit over factory installed Dex Cool, they lost. So your comment below regarding "Well they still use it..." has a caveat or two. Jiffy Lube refuses to use Dex Cool. But like you, I will be replacing my S10 coolant with Dex Cool as well as a GM stock thermostat (196 deg F). From what I read, it's imperative to flush all air out of the system as it's one of the triggers for the orange goop syndrome. Anyway's, I now have coolant leaking from around the intake (and have been smelling it as you mentioned in this video series) and with the above vacuum leak, figure my intake gaskets are toast. Bottom line, I would have never been able to efficiently R&R the intake without this 5-Part video series. Thank you very much for the time and effort it took to produce and publish "98 S10 Vortec 4.3 V6 Intake Gasket Replacement". Thumbs up and subscribed. Only wish is that there was a Bill of Materials to go along but I'm not complaining!!!
Getting ready to work on this tomorrow. Water pours out driver side front port where it connects to head, I expect the top part of the gasket to be completely missing. This video helps familiarize me with most of the things I will encounter, although I will probably avoid taking any of the top plastic part of the manifold apart. You did good job showing bolt locations and some wrench sizes, plus sometimes it helps to show more detail in electric plug lock mechanisms as they are all different and sometimes they get broke before you find the right way you ‘ should ‘ have pried on them ( or should not have )
Thanks for figuring all this out. I'm still not looking forward to tackling the job on my wife's blazer but at least I'll have your videos to refer to if (make that when!) I hit a snag. I call this an "all you've gotta do" job. All you've gotta do is spelled out in the service manual in about 4 paragraphs but it's never as easy as the book would have you think. Thanks again!
What an excellent set of videos. I have a British-spec 1999 right hand drive Blazer & my intake gaskets have been weeping for a while. I have just bought a set of gaskets & plan to do the job as soon as the weather warms up a little. Your video has been a great help in damping some of the worries I have had about doing it. Although mine is right hand drive the job should be roughly the same apart from some of the components are the opposite way round & the A/C lines are routed differently.
Hey man, great job and a great video. I just did this job on my 98 GMC 1500 and it was really nice to have this for reference. You're very thorough, I can appreciate that- so am I. I did most of the stuff you did. Got lucky on the distributor, it got turned around all kinds of ways in the day or two it sat around. Got lucky. Thanks and I hope both our trucks continue to serve us well. Mine's been in the family since new and is at 118k. Its still in great shape. Next I need to do the door hinges and it'll be good for another 100k or so.
by the way I really enjoyed the 5 video series and I'll be using it as an instructional video when I do mine, I'm just waiting for the fel-pro gasket kit to get here. Thanks again it was VERY informative.
By far, Yours was the BEST HOW-TO DIY video on replacing the 4.3 V-6 Intake manifold gaskets. THANK YOU FOR YOUR GENEROUSITY! Did you use MOTOR'S or CHILTON as your reference?
Thanks, I tried to find a good video on this process and really didn't find one with much good info. Most guys just said "take this off and that off and that off". Well taking something off can be difficult if you have never done it before. So I tried to explain everything especially when I had trouble. I believe I had a Chilton manual. Even those sometimes say "unbolt and remove". I would have replaced a few more things but I had a limited budget. Glad the you found my videos helpful.
Awesome Job I have that some problem my intake is leaking coolant on my 1996 s-10 v6 I took it to the shop and they are going to charge me a arm and and leg I will take on this job with the help of your videos and save cash thanks!!!!
With the radiator cap off, you can pour coolant into the thermostat opening and fiil the engine before you reattach the water neck. Helps when you start it back up and purge the air.
Hey dude nice video. I have never done a spider system before. I've worked on Ford, GM. Honda, Mitsubishi, Toyota, Isuzu, My friend has an S10. She relies on her truck for work,( self employed) Does not have a whole lot of money. Thanks to you her truck was done quickly and she said it has more power than before. Thanks Very much.
A great job. Congratulations!!. I helped a lot to do it myself. Thanks for sharing. Very professional. Excuse my English because I do not speak.. Thanks you.
Great job on the videos!! I am going to do mine this coming week. Wish me luck!! Also, it appears as though you have the dreaded fuel pump sending unit issue also. I noticed the gauge dropped down to Empty after you started it. I just had my fuel pump replaced, which of course corrected that issue.
I put a brand new spider in mine today and have the upper manifold all back together and tomorrow I'll be putting it on the motor and then putting the valve covers back on, I heard it was alot easier to put the manifold back on with the valve covers off since I'm changing the gaskets on the valve covers then after I do that I'll be putting everything back together.
Thanks for getting back to me..I love my truck..Bought it off a mechanic that didn't take care of it... I also saw your Temp Gauge reading is much lower than my, my temp gauge reads 2 ticks before 210F ..... and my oil pressure is lower on mine.... Are these normal readings..? I know it's running too hot.. going change the water pump & thermo-stat...last thing is to flush out the cooling system ..do you have a video on this too ?
Nice videos ..from start to finish..very easy & lots of info to help you out...Going to fix my 2001 S-10 LS Model.. I can smell & see the Wet Spot of Antifreeze on the drivers side near the valve cover just behind the A/C mount ..No leaking just the wet spot on top.. I was always filling up the reserve tank too long.. The area that's tough to get to..I have to take my time...Video #4 showed the area for me... I have big hands.. So I'll take my time..my wife is handy too.. Thanks..! Too bad you don't live in Florida..! Did you notice the Gas Gauge was acting up showing Low Fuel..?
Fuel sender is most likely the fuel gauge problem. I did a video on a 2000 Silverado that pretty much is the same thing. th-cam.com/video/oopmggJcnkw/w-d-xo.html
Thanks for answering my question about the valve cover gaskets. Was also wondering if you've ever back flushed the heater core on this? I have an 02 Blazer with only 65K on it, but have had to do that twice because it just wasn't cranking out the heat like it should. The 1st time I did it, when the heat was really weak, I heard a popping sound, like a vacuum releasing, as soon as I uncorked the heater hose on the firewall. I gently back flushed it and got a whole bunch of junk into the bucket I was flushing into, including some fairly big nuggets. The filter screen on it had to be really blocked a lot. Ran it until it was clear & the difference in the heat was incredible. The 2nd time I did it I got a fair amount of gunk in the bucket, just not as dramatic as the 1st, & the improvement with the heat wasn't as much either (but it hadn't gotten as weak either). I'll probably back-flush again when i do all of this project. Thank you, your 5 videos here are outstanding!
+Tim Karges Yes, I have flushed out the heater core. Here is the video th-cam.com/video/bnX8pU73kbg/w-d-xo.html . I did this a couple times when I owned the truck.
I have a 1996 GMC JImmy with the same engine, v6 4.3L. I am in the process of doing the intake manifold gaskets and fuel injection. Thanks for your video it helped big time. HAVE A QUESTION , Some one put in Green antifreeze. Should I change it out to the dexcool or just put green antifreeze back in ??
Thanks for the video's they have been so helpful, my husband used all of them to change the intake gasket on our 96 Blazer. One question...its not wanting to start. He's sprayed starter fluid and nothing. He's gone over the timing several times and checked all sensors. Have spark on the plugs but it sounds like no fuel is getting to the plugs. Turns over but won't start so do you have any idea what he should check next? He also changed the computer or ECM. Could it be the fuel modulator on the spider? There is gas coming to it.... Thanks a lot
Amy Bond If he sprayed starting fluid in and nothing happened then I don't think you have spark. It should have started and run on the starting fluid for a second. I don't recommend spraying starting fluid in the engine. Check the distributer cap and rotor. You may have spark but not at the right time. Very important the distributor went back in the way it came out. The fuel pressure regulator is in the intake. I changed mine out while I had everything off. On the 5.3 and 4.8 a bad fuel pressure regulator can cause hard starting. Make sure your fuel pump is working. Not being able to see it for myself all I can really do is guess.
Thanks for the great detailed video. I have to do the same on 2000 s10. Is there any other parts you would recommend replacing while doing the intake gaskets? I am going to replace all the parts that you replaced. Thanks again for the effot you put into this video!
You are welcome. I don't know of any other parts to replace. The spider injector assembly would have been a easy part to replace but at $200-300 I will wait until it has problems. My truck has been running good so far.
I'm about to tackle same job. Found coolant in oil. Fricken stuff looks like brownie mix coming out of the pan. Hey bud, I see your gas gauge jumping around while keeping 500 RPM. Is your truck having an issue with it? My gauge doesn't work either... any vids of you working on that other than replacing pump and sending unit? I have done that already and still no go on the gauge. Also, I heard the gasket issue is related to the use of Dex-Cool.
If you changed the fuel sending unit in the gas tank then your stepper motor is probably bad in the gauge. Or maybe a ground issue with the wiring. Dex-Cool doesn't cause gasket failures. They are still using it today on the new cars. GM got a bad batch or cheaped out on the gaskets. My gasket looked very cheap. Replace it with a good quality one and you won't have the issue again. You aren't suppose to mix the Dex and the green coolant. So unless you plan to flush the whole motor and cooling system you need to stick with the Dex-Cool or you are going to have more issues.
hello !, thank you very much for this excellent vidéo, congratulations for your great work ! and very well explained, i'm going to work on my CHEVY BLAZER 4.3 . hello from FRANCE ! éric
The videos were great and very informational. did replacing the gaskets fix the oil leak that was at the back of the engine that you mentioned in the first video?
just wondering if you kept the truck long enough to see the intake gaskets leak again. If so, how long did they last? i don't remember you saying the brand of the gaskets you used, unless I overlooked that. thanks for posting.,
Like all companies these days Felpro has "economy" gaskets too. You need to spend more money and get the better ones. It's been to long now so I don't remember the exact set I used.
+Michael Senter: These vacuum lines connect on the driver's side in front of the brake booster. They ultimately connect inside the truck, under the dash and control the vent blend doors. If you have problems with your HVAC vents and controls not working properly, check these vacuum lines first. They are known to deteriorate prematurely.
Yeah we just got another 8 inches this afternoon into tonight I had to tractor out yesterday cleaned up the whole yard woke up this morning said to myself feels like snow went in for lunch came out and sure enough snowing like crazy what's wrong with the dually battery dead
We have had about 3" total of fluffy snow so far. I have to do some more plowing tomorrow so I don't know yet if the batteries are bad or not. Today the volt meter was way below 14v. So the alternator might be the problem. This is the first time the volt meter has read like that so I don't know if the batteries wrecked the alternator or what. Jump starting the truck every day is getting old.
Jeff Everett Also let me see if i have this straight for the distributor part, mark (on the firewall) where the rotor is pointing, and as well mark on the distributor itself where the rotor is pointing (mark one) and then while pulling distributor out as the rotor turns mark where it stops (mark two). Now when putting back in, i line the roter up with (mark two) on the distributer and then line the roter up with the mark on the firewall, and as it drops down it should turn the roter to line up with both marks, the one on the firewall as well as the (mark one) one on the distributor..is this correct ? Been a while since i did this!
Jeff Everett I don't remember all the tools needed but you should have a good set of metric wrenches. You need a metric crows foot. I believe I tell what size in the video. I also think you need some star sockets. I think I point out any special tools needed in the videos.
Jeff Everett I think the distributor cap only goes on one way. It is pretty hard to explain this in a message. You don't need to make any mark pulling it out. Just make sure the rotor and the distributor body go back where they were when you pulled them out.
Very nice series of videos. I am doing my 2002 Silverado right now. I have a number of differences but basically the same. Curious, why did the fuel gauge suddenly go to E and the Low Fuel light came on? Thanks for the videos!
All around the truck is running stronger I think. All the roads are covered with snow right now so can't tell if it is better of idle but I am pretty sure it will be.
If you forgot to tighten the distributor hold down, you will need to go through the timing steps. Putting the engine on #1 compression stroke and aligning the distributor accordingly.
I have a 01 Chevy blazer ls and I'm about to do everything you have done but my question is I see you gas Guage does the same thing as mine moving back and forth do you know the reason why? I'd like to fix that to while I'm at it
mossman381 I've got a question that I kinda need the answer as soon as posable, I've done everything you've done in your video except 1 problem I put everything back together and forgot to plug in 2 connector plugs one goes to the distributor and I was able to plug that in but I can't find out where the other connector plug goes to, it is a whiteish oval plug that has a light green base that keeps water from getting in, and like I've said I got the distributor connecter plug in now but I can't find out where the other connector plug plugs in at. but the distributor wire and this wire I can't find where it goes come out of the same area of the wire harness. I'm sure you know where this goes that is why I'm asking you first
Great job and a good idea to replace all of the items that are impossible to get to without removing everything again. Do you have any idea of the total cost of the parts? I can only imagine what it would have cost if you paid someone to do the work.
I had to look carefully to see, but based on your voice, I would have sworn you were David Chappelle, from Motortrend Dirt Every Day. You guys sound remarkably alike.
Hard to tell you anything without seeing the truck myself. Did you get the distributor back in the same spot? Drop something in the motor? Oil in the motor?
A knock in a motor is usually a rod bearing. If you have a tick that can be many things. A bad injector will cause a ticking sound. Is it running good?

Great job on the videos!! I am going to do mine this coming week. Wish me luck!! Also, it appears as though you have the dreaded fuel pump sending unit issue also. I noticed the gauge dropped down to Empty after you started it. I just had my fuel pump replaced, which of course corrected that issue.
Good luck. This truck had the broken fuel pump sender.
I put a brand new spider in mine today and have the upper manifold all back together and tomorrow I'll be putting it on the motor and then putting the valve covers back on, I heard it was alot easier to put the manifold back on with the valve covers off since I'm changing the gaskets on the valve covers then after I do that I'll be putting everything back together.
Thanks for getting back to me..I love my truck..Bought it off a mechanic that didn't take care of it... I also saw your Temp Gauge reading is much lower than my, my temp gauge reads 2 ticks before 210F ..... and my oil pressure is lower on mine.... Are these normal readings..? I know it's running too hot.. going change the water pump & thermo-stat...last thing is to flush out the cooling system ..do you have a video on this too ?
Nice videos ..from start to finish..very easy & lots of info to help you out...Going to fix my 2001 S-10 LS Model.. I can smell & see the Wet Spot of Antifreeze on the drivers side near the valve cover just behind the A/C mount ..No leaking just the wet spot on top.. I was always filling up the reserve tank too long.. The area that's tough to get to..I have to take my time...Video #4 showed the area for me... I have big hands.. So I'll take my time..my wife is handy too.. Thanks..! Too bad you don't live in Florida..! Did you notice the Gas Gauge was acting up showing Low Fuel..?
Fuel sender is most likely the fuel gauge problem. I did a video on a 2000 Silverado that pretty much is the same thing. th-cam.com/video/oopmggJcnkw/w-d-xo.html
Thank you 🇧🇷
Thanks that was very helpful, great job
Glad to help.
GOOD job and you were through!!
Thanks
Thanks for answering my question about the valve cover gaskets. Was also wondering if you've ever back flushed the heater core on this? I have an 02 Blazer with only 65K on it, but have had to do that twice because it just wasn't cranking out the heat like it should. The 1st time I did it, when the heat was really weak, I heard a popping sound, like a vacuum releasing, as soon as I uncorked the heater hose on the firewall. I gently back flushed it and got a whole bunch of junk into the bucket I was flushing into, including some fairly big nuggets. The filter screen on it had to be really blocked a lot. Ran it until it was clear & the difference in the heat was incredible. The 2nd time I did it I got a fair amount of gunk in the bucket, just not as dramatic as the 1st, & the improvement with the heat wasn't as much either (but it hadn't gotten as weak either). I'll probably back-flush again when i do all of this project. Thank you, your 5 videos here are outstanding!
+Tim Karges Yes, I have flushed out the heater core. Here is the video th-cam.com/video/bnX8pU73kbg/w-d-xo.html . I did this a couple times when I owned the truck.
great video! very helpful. Thanks alot
Jesse Cholo Glad I could help.
Agreat job thanks
Thanks You Muy friend a good Job,..
Excellent Tutorial.
Great job. I'm in the middle of a job like that on my 98 Sierra V6. It is of great help.
Thanks for sharing advises and ideas.
***** You are welcome.
Very good
I have a 1996 GMC JImmy with the same engine, v6 4.3L. I am in the process of doing the intake manifold gaskets and fuel injection. Thanks for your video it helped big time. HAVE A QUESTION , Some one put in Green antifreeze. Should I change it out to the dexcool or just put green antifreeze back in ??
They have green antifreeze that can mix with any type. I would get that stuff.
@@mossman381 Thanks for your reply.
Thanks for the video's they have been so helpful, my husband used all of them to change the intake gasket on our 96 Blazer. One question...its not wanting to start. He's sprayed starter fluid and nothing. He's gone over the timing several times and checked all sensors. Have spark on the plugs but it sounds like no fuel is getting to the plugs. Turns over but won't start so do you have any idea what he should check next? He also changed the computer or ECM. Could it be the fuel modulator on the spider? There is gas coming to it.... Thanks a lot
Amy Bond If he sprayed starting fluid in and nothing happened then I don't think you have spark. It should have started and run on the starting fluid for a second. I don't recommend spraying starting fluid in the engine. Check the distributer cap and rotor. You may have spark but not at the right time. Very important the distributor went back in the way it came out. The fuel pressure regulator is in the intake. I changed mine out while I had everything off. On the 5.3 and 4.8 a bad fuel pressure regulator can cause hard starting. Make sure your fuel pump is working. Not being able to see it for myself all I can really do is guess.
Thanks for the great detailed video. I have to do the same on 2000 s10. Is there any other parts you would recommend replacing while doing the intake gaskets? I am going to replace all the parts that you replaced.
Thanks again for the effot you put into this video!
You are welcome. I don't know of any other parts to replace. The spider injector assembly would have been a easy part to replace but at $200-300 I will wait until it has problems. My truck has been running good so far.
I'm about to tackle same job. Found coolant in oil. Fricken stuff looks like brownie mix coming out of the pan. Hey bud, I see your gas gauge jumping around while keeping 500 RPM. Is your truck having an issue with it? My gauge doesn't work either... any vids of you working on that other than replacing pump and sending unit? I have done that already and still no go on the gauge. Also, I heard the gasket issue is related to the use of Dex-Cool.
If you changed the fuel sending unit in the gas tank then your stepper motor is probably bad in the gauge. Or maybe a ground issue with the wiring. Dex-Cool doesn't cause gasket failures. They are still using it today on the new cars. GM got a bad batch or cheaped out on the gaskets. My gasket looked very cheap. Replace it with a good quality one and you won't have the issue again. You aren't suppose to mix the Dex and the green coolant. So unless you plan to flush the whole motor and cooling system you need to stick with the Dex-Cool or you are going to have more issues.
hello !, thank you very much for this excellent vidéo, congratulations for your great work ! and very well explained, i'm going to work on my CHEVY BLAZER 4.3 .
hello from FRANCE !
éric
geo trouvetout You are welcome.
The videos were great and very informational. did replacing the gaskets fix the oil leak that was at the back of the engine that you mentioned in the first video?
Thanks, been a long time I don't remember a leak on the back of the engine.
I think in the first video at the beginning you mentioned that there was a little bit of oil on the back of the engine
Good work. Now I have to do mine. I have 03 with no EGR so that's a little easier.
Now you need to figure out why your fuel gauge is spazing out. :-)
Great job, how long did it take from start to finish? A few days? How many hours roughly?
Phoenix Franks I am not sure on the hours. I took my time and tried to film it the best I could. I believe it was 3-4 days.
just wondering if you kept the truck long enough to see the intake gaskets leak again. If so, how long did they last? i don't remember you saying the brand of the gaskets you used, unless I overlooked that. thanks for posting.,
I sold it to a cousin. As far as I know it's still running fine. I used a Felpro gasket set. Don't cheap out or you will have problems again.
@@mossman381 Thanks for the response. I used Fel pro on mine a few years ago and they are leaking again. Just curious what your experience was.
Like all companies these days Felpro has "economy" gaskets too. You need to spend more money and get the better ones. It's been to long now so I don't remember the exact set I used.
Nice work ,
At 4:33, where do the vacuum lines go coming off the splitter? My S10 has a plug in the end of one of those. No clue where it needs to be going.
Michael Senter I believe the one went into the fender. Not sure what it does there. Looked like nothing but it's really hard to see it.
+Michael Senter: These vacuum lines connect on the driver's side in front of the brake booster. They ultimately connect inside the truck, under the dash and control the vent blend doors. If you have problems with your HVAC vents and controls not working properly, check these vacuum lines first. They are known to deteriorate prematurely.
Yeah we just got another 8 inches this afternoon into tonight I had to tractor out yesterday cleaned up the whole yard woke up this morning said to myself feels like snow went in for lunch came out and sure enough snowing like crazy what's wrong with the dually battery dead
We have had about 3" total of fluffy snow so far. I have to do some more plowing tomorrow so I don't know yet if the batteries are bad or not. Today the volt meter was way below 14v. So the alternator might be the problem. This is the first time the volt meter has read like that so I don't know if the batteries wrecked the alternator or what. Jump starting the truck every day is getting old.
Excellent video's. Do you have any on replacing manual clutch on 1989 K1500 (4x4) 4.3?
Ray Alford I don't have a video doing a clutch but I have done that job on an 88 chevy with a 350. Way before I got on TH-cam.
Thank you so much!!!
Ya did the upper and lower intake but i was told i have to doa cam sensor relearn
Didn't have to do that for mine.
Why did you fuel show full and then Empty a couple times? Is that the fuel pump sending unit issue that S10s are known for?
My guess would be fuel sender.
Why was that fuel gauge jumping around rapidly from full to empty?
Probably the fuel sender in the tank.
So what were the actual tools needed and sizes of sockets? I am attempting this but want to make sure i have everything before i start.
Oh, i have an olds Bravada 4.3 so i assume pretty much same engine, is this correct?
Jeff Everett
Also let me see if i have this straight for the distributor part, mark (on the firewall) where the rotor is pointing, and as well mark on the distributor itself where the rotor is pointing (mark one) and then while pulling distributor out as the rotor turns mark where it stops (mark two). Now when putting back in, i line the roter up with (mark two) on the distributer and then line the roter up with the mark on the firewall, and as it drops down it should turn the roter to line up with both marks, the one on the firewall as well as the (mark one) one on the distributor..is this correct ? Been a while since i did this!
Jeff Everett I don't remember all the tools needed but you should have a good set of metric wrenches. You need a metric crows foot. I believe I tell what size in the video. I also think you need some star sockets. I think I point out any special tools needed in the videos.
Jeff Everett Same truck different grill I believe.
Jeff Everett I think the distributor cap only goes on one way. It is pretty hard to explain this in a message. You don't need to make any mark pulling it out. Just make sure the rotor and the distributor body go back where they were when you pulled them out.
THANK YOU!!!
+Jason Chinchen Glad to help.
Very nice series of videos. I am doing my 2002 Silverado right now. I have a number of differences but basically the same. Curious, why did the fuel gauge suddenly go to E and the Low Fuel light came on? Thanks for the videos!
Glad you enjoyed the videos. I am guessing the fuel sender in the tank is bad.
Yeah, another PITA to repair.
Oh by the way, check out my video to make a water pump pulley holding tool! It's a lot better than a screwdriver.
beninchesapeake fuel sender sensor in the fuel pump is bad, fuel pump will go soon also. Curse of the Chevy intake gaskets and bad fuel pumps.
How is it after you trimmed up the throttle body any difference
All around the truck is running stronger I think. All the roads are covered with snow right now so can't tell if it is better of idle but I am pretty sure it will be.
Good imfo
How difficult would it be to pull all the lifters once I have the intake manifold off?
Well you have to pull the valve covers then rockers and pushrods. Not too difficult but then you need to adjust the rockers when you put them back on.
I just put everything back together and the truck started ran for a little then cut off. Now it won't start. Any suggestions?
I would look at all your electrical connections.
@@mossman381 I did I think the timing jumped off. Any suggestions for getting it times right?
If you forgot to tighten the distributor hold down, you will need to go through the timing steps. Putting the engine on #1 compression stroke and aligning the distributor accordingly.
I have a 01 Chevy blazer ls and I'm about to do everything you have done but my question is I see you gas Guage does the same thing as mine moving back and forth do you know the reason why? I'd like to fix that to while I'm at it
Common issue with the fuel sender in the tank. Not the same truck but should be the same issue. th-cam.com/video/oopmggJcnkw/w-d-xo.html
mossman381 isn't that sensor in the top of the tank and you gotta take the take down to change it?
TheDizizope Yes, tank has to come out or take off the bed. Not sure where the blazer fuel tank is. That video link shows exactly what it is.
mossman381 i watched it thanks. the blazers tank is in the very back under the cargo area.
mossman381 I've got a question that I kinda need the answer as soon as posable, I've done everything you've done in your video except 1 problem I put everything back together and forgot to plug in 2 connector plugs one goes to the distributor and I was able to plug that in but I can't find out where the other connector plug goes to, it is a whiteish oval plug that has a light green base that keeps water from getting in, and like I've said I got the distributor connecter plug in now but I can't find out where the other connector plug plugs in at. but the distributor wire and this wire I can't find where it goes come out of the same area of the wire harness. I'm sure you know where this goes that is why I'm asking you first
Check the fuel reading
after I finished it made high noise when I started it I tried to press on gas pedal there was no pressure at all what do you think
You might have to cycle the key a few times to get the fuel pressure where it needs to be.
thanks man this problem is solved but everytime I start it it makes a lot of random noise I don't know why
I hope you didn't drop something in the motor. That would be really bad.
Great job and a good idea to replace all of the items that are impossible to get to without removing everything again. Do you have any idea of the total cost of the parts? I can only imagine what it would have cost if you paid someone to do the work.
bg147 It was a long time ago so I don't remember the total cost. It is an expensive job to pay someone to do it.
this guy is legit he does shit right .. damn I would like to have him as my mechanic
Brandon Summers Thanks, I always try to do my best when working on stuff.
Bouncing fuel sender! There goes the fuel pump on the downward spiral. Maybe all the heat from ethanol fuel is burning up the gaskets?🤔
I have heard people say that but I have has two gm trucks with bad fuel senders and the fuel pumps still work great.
Well i think i dropped a plastic sleeve from the fuel line in the intake
I had to look carefully to see, but based on your voice, I would have sworn you were David Chappelle, from Motortrend Dirt Every Day. You guys sound remarkably alike.
looks like you have a problem with your fuel gauge sending unit,or wire connection,it goes from full to empty in less than 1 second.
Common issue with these. Fuel sending unit in the fuel tank.
Someone stole all your fuel. Gauge shows on empty.
Nice job!!
The fuel sender is bad I think. I have a new one just waiting for a good time to take the box off and put it in.
I figured as much because I saw it go from full to empty on the video.
I can shake the truck and get what ever fuel level I want.
LOL!
mossman381
Why would you ever want empty then ! hahahaha
Mine is knocking why
Hard to tell you anything without seeing the truck myself. Did you get the distributor back in the same spot? Drop something in the motor? Oil in the motor?
I think you fuel gauge is bad.when you 1st cranked it it was full then after bleeding air it was empty.😮
Most likely the sending unit in the tank. GM vehicles are known for that. I sold the truck before fixing that.
They say to stop using dexcool,that shit will mess you up!
I don't believe that. They wouldn't still be using it if that was true.
Its only coming from the one side the drivers
A knock in a motor is usually a rod bearing. If you have a tick that can be many things. A bad injector will cause a ticking sound. Is it running good?
looks like your gas gauge broke
chris s Yes, like most of the s10 trucks still running.
