Water pump bad on 86 buick lesabre

I have an 86 lesabre, 3.8, 6 cyl., that the serpentine belt came off while i was driving. Turns out, the water pump pulley was loose and wiggles up down and sidways. There is also coolant running from water pump. Question is, how easy is it to replace the water pump? I have basic hand tools, but the car is at my workplace parking lot- i don't want to try tearing 1/2 the engine down, if I take a long time they will make me tow it.
1. how long should it take for a non-mechanic who can do a good tune-up but not rebuild an engine?
2.once it's done, do i need to flush coolant? I'll need to drive it about 10 miles to get to a place I can flush & I'm worried about metal shavings in coolant system.
3. Thanks for the help!!

Which way is the motor facing? Is it front will drive or rear wheel? If the motor pullys are facing towards the front of the car you may need to take out the radiator for more excess and if its pointing towards the wheels or the fenders then you need to take off the wheel and maybe the Black inner fender covers to get more room. After that it should be pretty easy just some bolts and when you put the new one on make sure to put some sealant on the pump to make it water tight like around where the blots go on the flat part. It should only take a few hours or less but take your time and make sure you do it right. You will have to flush it though to get the bad **** out. so bring lots of water and when you get it home flush agian and put coolent in it. k hope this helps and also it helps to get a book like a chilltons or a Haynes book on your car cus that explains how to fix anything on your car and shows step by step. well hope it all works out for you.

It should be a friont wheel drive car. First thing, look directly in front of the water pump. The bolts that hold it on are about 5 or 6 inches long, so if there is a motor mount in the way, you may have a bigger project that you would want to tackle. If you can get the bolts out, find a big basin to catch the coolant.

1. One to two hours max if you are a little bit mechanically inclined.
2. Not really, unless the color of the coolant is rusty or dirty looking. The usual coolant color is a greenish yellow. There is another kind that looks orangish. If it has oil in it, there are probably bigger problems and I would probably have a mechanic look at it.
3. Your welcome!

Google is your friend! Search for a manual online to help you. There are prolly a lot of places that say free manuals, and I am sure you know what that REALLY means, lol. Just dig through all the ****. Your library may have a copy there also. Some parts places have them, and AUTOZONE has online manuals, free, but you have to sign up. I forgot all about them, I have been signed up for a few years, and get no spam, but today I opted in for a couple newsletters. Hope this helps!

If you do replace it, get a decent 5 in 1 or 6 in 1 scraper, usually in a paint department at a place like Home Depot, to scrape the old gasket off the engine.

Power steering resevior for a 1999 buick lesabre


Yeah, that's a fun one but not as bad as you think. Make sure the car is cool because if not..... well you'll see. Anyway, you'll be on the passenger side of the car looking at the engine. Look to the left of the water pump pulley and behind the serpentine belt. look straight down or you'll miss it. It's a black cap with red lettering.

1995 Buick LeSabre with a leaking water pump.


The water pump removal is a breeze on this vehicle. First remove your four bolts that hold the pully to the pump, then remove the serpentine belt. Next remove all bolts from water pump, now the fun part, pry the housing of the water pump off gently trying not to nick or gouge the engines placement for the housing. now all you have to do is make sure the housing is clean of all debris or old gasket material, you wouldnt want any of that gunk getting inside. nowplace your gasket properly on new water pump and place on housing. make sure the gasket fits nicely. reinstall pully to water pumy, reinstall your serpentine belt, place new antifreeze, I prefer the peak green full strength, make sure to mix correctly also. start engine let run for 5- 10 minutes and then let cool down and check levels. hope this helps.

Torn Serpentine Belt. Bad belt driver


You say belt driver? The belt runs on a series of pullys, there should be a pic./diagram on the radiator support that shows the routing of the belt. simply take the belt off and check each pully( they will either drive the belt or be idlers/tension pullys)to see which one has any "side to side" motion. If it is on a "driver" you are looking at replacing that part(water pump,power steering pump. etc.), as the real problem will be a bad bearing in that unit.
