How-To: GM 3800 Series II Water Pump Install (Step by Step)
ฝัง
- เผยแพร่เมื่อ 14 ต.ค. 2024
- In this video, I go over a detailed install of a water pump in a ~100k mile '98 Buick LeSabre with a 3800 Series II motor. The gasket had started leaking near the bottom of the pump and the car had steadily been losing coolant till it became a larger evident leak. No overheating until the car had lost enough coolant. I had earlier misdiagnosed the leak as coming from the tensioner coolant elbow(s). These tend to leak in the same areas and the plastic elbows tend to disintegrate over time as evident when they were removed/replaced. This video covers the water pump replacement which fixed the leak. I used an aluminum framed gasket that came with the pump.

these 3800's are impossible to kill, I swear
Thank you for letting me know where the power steering bolts were top and bottom that's all I needed that was great everyone else did not share that good job
great video, I really appreciate you fast forwarding thru the 10,000 1/8th turns on each bolt, I wish others would follow your example on that!!! Thank you, I would have never guessed that I would have to remove the freaking power steering pulley to get to that last bolt.
Thanks Steve for the response. I agree nobody wants to watch a bolt get turned slowly and its why you just see it cut out most of the time. The problem is it doesn't show the viewer what may be required especially to get into difficult positions if you don't have a larger variety of tools. I did this video while visiting my mother with her basic set of tools. Hopefully that inspires others on how basic this job can be with patience. The trade-off is extra time needs to be spent in editing which a lot of content producers on youtube either don't want to spend the time doing or understand how to do it.
He forgot to mention something REAL IMPORTANT; That it only takes 10 min 54 seconds to do this Job !
I found this video very helpful especially the two bolts on the power steering pump and dropping it out of the way as for the pit cock on the radiator I did not do that because I put a pan under the engine only dropped about a half gallon of antifreeze out of it didn't have to take off the top engine cover no need other than that excellent video
Thank you for taking the time to respond with such an appreciative comment, makes doing these videos worthwhile. Glad it helped you out!
Where exactly on the pump does the inch and a quarter bolt go into . I tried the farther on the left bottom of you are facing the pump and it seems like it will go in about a third and bind . Kind fraud to go any farther. Sm I putting it in the wrong place?
Did you use any thread sealant on the four larger bolts that you call 1/2 inch but really are 5/16 inch and take a 1/2 inch socket? Those four bolts go into the water jacket and I've heard of people having leaks from them after installing dry.
I use Vaseline in my #%$# so that I can listen to snarky comments on a 6 year old video that I don't even have monetized.
You mean to tell me you didn't get rich off of this video? LOL

Great video material thanks alot 👍🏾
Hey on my buick lesabre i dont think i have to remove the power steering pulley to take off the water pump. It looks like i can just take it of with out remove
Fantastic well organized vid mate! Have a 1999 eighty-eight with 198k and ready to install another water pump (bearings going out). Always like to refresh me self with a vid before the task! If you don't mind what brand of pump did you use.... it looks nice. Thx
Oh yeah, they're a ton of these cars still out there, glad its helping folks out. i went with a gm factory pump iirc, maybe delco?
@@FuelSniffer I did as well! Seem to be a good choice. Thanks
Does anyone know what part is the one just above the water pump, it looks like a hose but idk what it is?
What a great video thank you
Are there hole in the power steering pump pulley?if there are,is it possible to rotate one of the holes over the hidden bolt on the water pump?
Then get to that bolt through the hole?
yes, that is shown in the video.
I’ve got a 96 bonneville and I noticed the power steering pulley was in the way of one of the bolts and I knew I had to mess with that a little bit, I’m also replacing my radiator and driver side cooling fan. The most work out of all of this is clearly the water pump I’m glad you posted this, I haven’t had the belly pan on for some time and one of the bolts was missing from my old water pump and I was wondering if that had caused any problems in my engine cooling?
well a missing bolt could prevent the pump from getting a complete seal and then prone to leak which would obviously drain your coolant down which could cause overheating yes. would recommend replacing the missing bolt for sure. belly pan missing is not a big deal.
Question: does the belt need to be replaced? And if not, would I need to mess around with the motor mount to replace the water pump?
The hole where the piston looking thing inside the engine not the water pump. But the hole wgere you put the water pump on. The surface is really dimpled and coroded like a lava rock HOW DO I FIX IT!! My grandma passed the car down to me to make sure it stayed healthy and i dont want to have the engine rebuilt.... Someone please help
Hey so u dont have to take off the mount to change the water pump
It's important to note that even though this is a series II 3800 motor there are important differences between years. The Series II motor was introduced in 1993 and ran into the early 2000's. I have a 1993, the first year, and the power steering pump is not located where yours is in 1998. My power steer power is far enough away from the water pump that it doesn't even come into play. Nor does the 1993's have that motor mount sticking out into your working area. You might want to retitle this video to state that it's the later model Series II engines as others may get confused why their Series II doesn't look anything like yours in the video.
See my problem is that somehow the pulley is so close to the fuse box that I cant get anything in there to get the bolts off of the pulley. And the pulley covers two bolts that need off to remove the water pump
@@lowkeymodzz you have to use what are called in the business, "ratchet wrenches". They allow you to get the wrench on bolts with very tight clearances. Hope it helps.
Thanks for clarifying that Kenneth, I figured there could be variations even between car models as well, but didn't realize there were more between years. I didn't want this searched purely on just a Lesabre realizing it could help someone else out with a later Series 2 in another vehicle as well. I will see if I can update the title.
@@klwthe3rd yeah thanks for that. My car has been sitting since I commented that😂

Very useful video. You saved me a good chunk of change. Is there anyway I can contact you direct just in case I have any questions while working on it? I'll feel more secure as this would be my first time doing any work on a car
I found a black clobber under the radiator cap. It that caused by burnt coolant?
great video, I have a 98 lesabre Isnt overheating but seams to have no upper and lower hose pressure even after replacing thermostat, cooling fan comes on at 200f. The heater hoses seam warm do have any advice for a rookie mechanic thanks.
190 - 210 sounds like a normal temp range
Good video,could have had a little more lite on the subject 👍
Sure hope thats the Camera Wobble, and not the😂 Car 😂 LOL
Is the torque spec good and tight Clem? Haha great video though I had to click on Fuel sniffer of course
That's shade tree mechanic torque spec ;)
FuelSniffer my water pump gasket is visibly cracked and leaks when hot 😩🥰
Thank youuuuuuuu 😃
Perfection
You mentioned the engine mount making the belt removal difficult, but didn't cover disconting it to put the new belt on. You video is very dark and it's hard to see what you're doing. That motor mount ain't no joke.
Yeah I'll get right on that lol.
I have the exact same vehicle but am having troubles turning the petcock. Help?
Bryce, try using a set of pliers to grab the base, and then twist counterclockwise. should help you get some leverage
My water pump just took a shit on me now im having to have to replace it

Does everyone know how to change a water pump on a 1986 Oldsmobile calais and how do I get the pull off got know bolts on it
Good video thank you....only an idiot would thumb this down..
Definitely, thanks for the response! Yeah don't put too much on the down votes, people are angered about life in too many ways to comprehend.
How long did this take? And is it the same process on a 97 lesabre limited?
Maybe 90 minutes? The key is having all the tools you need out and ready. I was also filming while I did this.
