- Come along wit Eric O at SMA and let's have a look at this 2006 Jeep Grand Cherokee that tends to run a fever if it is left sitting. Not only do we diagnose a bad fan assembly but we get to play around with the Bosch VCI module and check out some of the bidirectional functions of it.

As the owner of 2001 Jeep GC, that is one of those rare vehicles where you eventually get to repair everything...Keep up the great vids !
@@jeepsblackpowderandlights4305 I keep cars 15 to 20 years. They always get junked because of rust. (all Fords) The most I've ever had to replace other than consumables are a few tie rod ends and a couple of wheel bearings. The ONLY engine issues I've ever had on any of them has been a thermostat and an idle solenoid. That's across about 5 vehicles bought new. My current car is a 2007 Fusion 4cyl with a stick shift. One tie rod end, one rear wheel bearing, 205,000 miles. Definitely FAR from having to fix "everything"
A friend just took her Wrangler in to figure out why the steering was so bad - basically the ENTIRE front suspension and steering gear was shot, two ball joints, all the tie rod ends, bunch of bushings, etc, needed like $3000 in parts and labor. At 135K miles. It's never been off-road. I'm not inclined to ever buy a Jeep.
You can date these videos by the condition of Eric's Jeep hat. That thing has had a hard life in the last 3 years.
I just sent him a couple of new Jeep hats, we'll see if they show up in future videos.
Don't forget the beard
That hat has seen some things 😂
I can't even describe how fast I click on your videos when I see them. Because of videos like yours, I got a job starting at $20/hr working on cars for an independent shop.
I'm self taught I've been working and learning for about 18 yrs and yep your certificate means great test takers honestly. Real world is your best teacher
@TheStyles4life
Why ? Eric didn't have ASE or anything like that. I would rather have him work on my car than any of the so called CERTIFIED mechanics. I do my own though.
@Never Gonnatell YOU DONT NEED 20K IN SCAM COLLEGE
Today's mechanic not only needs to know how to turn a wrench but he needs to be a computer geek even more. Without the necessary computer tools the average guy at home can only try the shotgun best guess method and throw cubic money at a problem. I admire your prowess Eric.
I know your community is very grateful to have you and your shop there, I enjoy your videos very much.
Thank you SMA! Just got done replacing the non working fan in my 07 Commander. I only do short trips so I never noticed my overheating issue. Bet the fan was inoperative for months! The AC is now uncomfortably cold and I've been idling in the driveway for >30 min now with the temp gauge reading less than half scale, rock steady. All the best from Pittsburgh!
Hi Eric, thanks for taking the time &effort to produce these quality vids. Between yourself & Paul Danner, I am now no longer a diagnostic incompetent. Thanks again
I just realized why we love to watch these videos ,this is what we did as kids in the old days,we went to our local garage and hung out and learn ,if we were lucky enough we would work for free just to learn
thee days kids would demand 25$/hour and a long lunch break.
I just want to say that these are the best intro's you've made by far, Eric. Great work mate.
Two thumbs up for the Bosch demo. This kind of information is very valuable and hopefully you'll be able to show more of this kind of thing as well as some programming. Thanks for the great material.
Thanks for sharing your knowledge while you have a busy day. Impressed by your ability to manage. I'm sitting on my couch learning car stuff because I never had anyone to teach me. Thank you.
One of the many things I like about this channel is the fact that Mr. O is always changing tools and scanners. It is way more interesting... I don't get it why some one will dislike that!!
Because they like to complain...
My purge solenoid went out on my Dakota and took out the NVLD as well...I diagnosed the purge solenoid by wetting my finger and covering one of the vacuum ports...I wasn't thinking I could've used a vacuum gauge...Awesome video as always Eric!
thanks for showing us a great new tool to help us keep are auto's going. Will have to look into that one more. Great video as always.
Love the variety of scan tools. Looking forward to seeing you use the pico. I've been considering picking one of those up.
So great to see such professionalism and detail! So very difficult to find here in California! Almost non existent!
@Never Gonnatell sontrue and evident!
same here in Alabama.
Nice to see another video, understand you are very busy!! Keep up the awesome videos.
Beautifully made video Eric. Glad that business is good and all is well!
Thanks for showing us the new Scan tool. Appreciate that !!!
Variety, they say, is the spice of life. Bring em on, the more tools the better. Thanks for the video.
Nice little tool that Bosch...... Right on Eric O.....👊🏼👊🏼💯💯
I'm a mechanic and I love this it's just cool to watch and observe so maybe I can apply it or get a new toy
Excellent video Eric o thank you. Bosch makes nice stuff. I always liked their 4 channel mts 5200 scope
The *"Eric O Master Tool"* is the best.
Even the small repairs count , thanks for the video ! Oh yes and the explanation for antifreeze situation..
Good work Eric. I'm a new subscriber and these videos are awesome!
Thanks
Eric
Not only are you awesome
Your little jokes crack me up.
Can't wait for some reprogramming, Pico waveforms,non communication,and more great diagnostics. 😁😁
Air pocket
I like the intro with the black and white stills !
I thought you were doomed when you made the statement at the 6:12 mark, "Looks like a pretty easy change." That statement usually dooms me to extra hours of repair! :)
Utah York broooooo 😂😂😂😂😂😂😂😂😂😂😂😂factsss
eric you got reflashing abilities now my friend with the vci module! I use drewtech but ive heard good things about the bosch
You will love the pico scope have one at our shop very powerful scope with many cool features.
Fantastic video Eric!!!!...thank you for your recommendation on That Bosh tool!!!...definetely worth to check it out!!!!.....Greetings to all at SMA!!!! :) :) :) :)
Nice job!!! Got the cooling fan blues on my sister's 2000 Impala 3.8...Seized up popped a fuse, and triggered the circuit malfunction code. Seeing you do this jeep reminded me that I have to remove the upper radiator hose as well 😞 I tried squeezing it around the hose and damaged the coolant level sensor! When I get the new one I'm going to drain the coolant maybe I can find one of those fluid extractors since there's no drain.
Hey Eric.
To close any active window on the computer ALT +F4
Also helps to quickly shutdown the computer. ALT + F4 Enter
Might save ya a couple of seconds.
Awesome videos, I've watched pretty much all of them.
I fixed a car with same issues but it was the radiator cap that was bad. It wouldn't maintain enough pressure and the coolant would boil before the fan switch/computer would turn the fan on at 220. So a new radiator cap allowed it to build pressure and the temp would reach 220 without boiling then the fan would kick on as it should. Anecdotally, although the car was fixed, it ended up coming back for a leaking water pump as the spring and seal was worn enough that it couldn't hold back the pressure caused by the new cap.
Thank you for another great video!
Quick and reliable diagnosis. But parts changers would change it immediately and would say we were right. Yes twice in ten times they really are.
Original idea for coolant extraction.
Greetings from Serbia.
Yep, had to replace the fan on mine, too. Along with rigging the leaky vacuum reservoir, changing out the frosted headlights, diagnosing faulty grounds (esp. in the door wiring harness), propping the busted mixer door under the dash, dealing with Death Wobble, deleting the destroyed 4WD tranny, upgrading the fuel injectors, unclogging the windshield wiper lines and replacing the seized washer pumps, beefing up the "knocking" front sway bar, wrestling with the brakes and smoking caliper, chasing down engine leaks, and buying a new radio when the factory one stopped playing.
Other than that, my trusty Jeep Grand Cherokee was a great ride!!
hey eric o,greetings from ireland love your vids looks like this is your 50;000 subs weekend congrats and keep up the great work
Ahhh thanks!
"Come on little fella, there she goes". Love it!
love your work and love the jeep its have very great space work area and love the new tool
great video, what surprises me is I didn't get the upload message from when your videos post. No biggie your not gonna lose me as a subscriber. lol. have a good day.
Thanks Eric keep'em coming.
I have the same issue with my 05 JGC limited. Thanks for the vid.
Wow bunch of space in there! Like that easy peasy
That Bosch module looks very handy. I like scan tools that do bidirectional testing and read live data. It looks like that can read live misfire data as well, very helpful. On a side note, you said the evap purge solenoid went bad previously in the week. Sometimes they activate the ses light like yours did, other times I have seen them cause a hard/extended crank immediately after a fuel fill. The gas vapors end up going into the intake causing I believe a temporarily rich condition.
Yep you are 100% right on that. They will flood the intake and have a start stall or an extended crank.
My 2007 Jeep WK CRD had a hydraulic fan. I only heard it run once, when I visited the Lava Beds National Monument in Oregon. I think it was 107 degrees at the time.
Great video. I have looked at getting a computer based scan tool but I haven't own an PC in 7 years. All mine are Macs and I haven't found any scan tools that work on Macs. Keep the videos coming.
Eric I really love these intro's.
Also, every penny I've saved on working on my own cars is down to you the other Eric; me and tons of others owe you a lot, so thank you for spending time bringing us along with you so we can all learn something :)
Thanks man!
That Bosch scan tool looks so cool it hardly matters if it works.
Always a great video. I learn something from each one of them. Thanks! Cheers! \m/
When you're swamped like that it pays to have numerous scan tools. Glad you are that busy! Nice quick diagnosis & repair.
You got that right!
I had a problem with a jeep like this . had a bad relay behind the passenger headlight and had to replace the plug going I to the relay also changed the fan .
Another great video. Thanks for showing us how.
Great video good scan tool with flashing capabilities
oh yes the artsy intro!! loved it.
My '88 Cherokee has one belt-driven, viscous clutch fan (had to replace it this summer with a junkyard fan because the viscous clutch was seized - the blades wouldn't turn freely with the engine off) and one electric fan. It turns on and off when needed, but I wired a direct feed from the battery with a SPDT switch to turn it on manually when needed.
Can't wait for your next vid ;)
Neat little scan tool !!
Eric are you showing us that you're a HUGE FAN of DORMAN Products once again lol, great video by the way and love the new scan tool it's like the one i recently got it runs Delphi and WoW from Wurth which are programming tools it's great for the electric rear brakes winding them in and out correctly.
I agree nothing worse then sticky coolant I like how you roll
Nice Video and nice scan tool! thanks!
Great job like always
I have that Bosch tool as the "GM" scan tool, its pretty nice. The only thing i don't have is the software you have i only have GM's software and access to flash program. I'm excited for you to start using the pico scope since the shop has one but GM only uses it for vibration analysis and won't show us how to use it as an electrical diagnostic tool.
those electric ratchets are one of the handiest tools. I have the snap-on electric ratchet and use it daily between dropping and cleaning DPFs and other random stuff like A/C work or the occasional front engine mount on a Paccar they are worth the money.
Nice scan tool I like it
Dorman for the win!
Love the videos.
Hi Eric, on that Mastertech scanner-programer it comes hardware and software? Did you need to buy extra software for OEM capabilities? On which car have you used?
Hello and thank you for this video.
Is that fan supposed to have two speeds? I have a 06 commander which blows cold ac only while driving. Fan is spinning, maybe not as fast as it should.
Thanks in advance.
Thats one huge fan.
Great video as always Eric O nice bosch VCI Bi directional module @SouthMainAutoRepairLLC
My Mum had a Toyota Corona Mk 2. The mechanical fan from the crankshaft pulley was removed (was damaged and replacement part then could not be found) and the auto shop installed a electric fan. He also installed a manual switch to turn on or off. No auto on or off. Was fun pulling up to a store and turning engine off, then manually turning off fan 10 seconds later. Would get alot of attention. This was in 1993.
Always try the flick trick. I put an aftermarket radiator in my wife's 01 Mustang GT. Swapped the OEM fan with 150k over to the new rad and got everything all buttoned up. Fan don't kick on all a sudden. Thankfully my pops was watching and said try spinning it while it's supposed to be on. Boom, problem solved. It must have just not liked being away from home that day.
Like you using old school tools. Boch sounds good.
You always say safety third and I like that and agree. I’m just wondering what comes first and second in that case?
ahh the jeep hat in its natural habitat
nice bosch setup... i still use the bent paperclip to pull codes from my 92 chevy van lol..
Haha perfect :)
Nice one Eric it's all PC factory scanners now I think.
Hi I was wondering what scan tool do you typically use on most of the subaru models that you work on. I know that based on the job you will use different ones. Really I'm looking for on that can talk with the modules and all the engine sensors.
Good job
eric I was the one wondering about scan tools I understand some scan tools work better then others on different vehicles so maybe I'll go this route then is the autel pro a good scanner and do you have any regrets getting it I've narrowed it down to 2 the verus pro because of the scope capabilities or the autel
How do I get one of your SMA t-shirts Eric. Great videos keep it coming thanks Dave.
Dude almost 50k subs gotta do a special vid for that!
3 years later he’s over 400k!
I'm not fond of Bosch appliances, but that tool looks awesome
Great video.
Eric have you ever tried a coolant retainer? This would allow you to remove that upper coolant line with out spilling coolant..
I performed the same test on a Pontiac Montana cooling fan. Diagnosed the fan. The new fan had the same problem. I ended up finding a bad connection in the fuse box. Enough connection to power the test light but not enough to run the fan.
I have a Bosch VCI too. Mostly use it to program, It can no longer be updated as of 2015. First time I've seen you use it. Stie sll a very nice tool.
You sure about that Tim?
That what my Bosch rep told me four month ago. Hope it's not true. I was not a happy camper. When he told me.
I just sent them an email to find out. They make this tool for many OE's so I doubt it is true. I am hoping he is mistaken too.
I don't have any swag to send you, but I got a 2004 Jeep that I'm about to utilize for target practice. I can send you that.
I'm with you, Amanda. I love Jeeps but this one has been a real ball buster from day one. If it wasn't for SMA and a few other TH-cam/web resources, I'd be ready to park this in front of my house, paint it white, and plant flowers in it...
I have an MDI 2 that I just purchased because I am a GM Dealer tech. It is also a J-2534 tool so I'm wondering if it can work with this Shop Foreman program?
Great video Eric I was thinking of getting that Bosch tool, but I was under the impression that you had to purchase a license from a dealer to use it as a scan tool, I know you have to for programming, I was just going to ask you when you was getting the pico, I just bought a pico myself it will be here tomorrow!! I cant wait I am like a little kid the night before Christmas waiting for it. LOL
The pico is amazing! and overwhelming at the same time haha
I found a modis ultra for sale on craigslist and a Verus. look under buffalo craigslist. But seriously Eric you should have a Saturday scan tool/labscope class. But do it after hunting season lol
I have a 2006 with the same problem. I see the high and low relays in the box behind the battery. Is their a power relay under the passenger headlight also?
That Bosch Vci is the same tool as the gm Mdi, I bet if you could acquire the gm gds2 software the Bosch unit would work with it
Hey have you seen a lot of the Jeep Liberty vehicles with spun bearings and other catastrophic failures? If so have you been able to pinpoint a common cause? I have seen so many of these for sale with the 3.7 that have engine failures.
I had a 1998 Chrysler Concord with the same problem, what I found each motor had a seprate ground, both were bad. Made up new ground wires, and they worked great. I must have been lucky, compared to this.
My Chrysler had 2 small fans one came on at around 195 degrees then the other at 205 if I remember correctly
thanks a lot that looks like the real deal
Great videos
Eric installs a DORMAN replacement component...I thought I'd never see the day. :)
I hang my head in shame
I have a cheap Pico scope, haven't used it much. But I love to see that in action. Guess you get a lot of nice stuff for free to test out and show us. Almost 50 thousand subscribers and increasing makes companies throw stuff at you :-)
My wallet gets all of my tools
Oh, my bad. I just know that some other TH-cam mechanics have that problem, free tools.
Eric I have a question...I have a 2000 grand cherokee, it also has a single 2 speed electric fan. When I turn the a/c on in my 1998 cherokee and another vehicle I have the fan instantly comes on. On the grand cherokee the fan comes on when the temp rises to 210 on the temperature guage, but when I turn the ac on the fan doesn't spin. Do you know how this 2 speed fan works ? I have replaced the fan relay, but not the fan. Could the fan be faulty ?
