2000 Buick Lesabre. I had my oil changed. With all previous changes the mechanic never put more than 4 quarts n my car. This mechanic put 5, now I have a oil drip under my car. What did he do wrong ?


My info says 5 quarts with filter. I don't know where the leak is coming from? My database isn't always correct, but, that's what it said.

Why rearend leaks by both wheel areas 2003 lesabre?


this is a front wheel drive car there fore there is no rear end like a rear wheel drive. the fluid leak at the wheels is probably brake wheel cylinder/caliper or brake flex hose. check brake fluid level if its down then check for brake fluid leak if not then you will have to check the rear area for some other fluid leak.

1998 buick lesabre wont start. had a new thermostat installed last week as heater was blowing cold air. mechanic added anti freeze, car was running fine and blowing hot air. today the check engine light...


Sounds like you have water in the oil which means you could have a blown head gasket. Can you tell what got in the oil. Is it antifreeze or gas. If gas you probably have a injector sticking open.

How many quarts of oil in 89 buick lesabre?


Should be about 4.
When you add 4, then park the car on a level surface, and wait about 15 minutes, and then check the level with the dipstick.
The low line and the full line are 1 quart apart.
Be blessed.

Trans-axle fluid cooling ,all fluid gone


If the trans. fluid gets down , even a quart, it usually starts to slip or not shift right. Check the fluid with the engine running and warmed up on level ground (in park). If it's low start adding fluid about 1/2 a quart at a time and keep checking it. Watch for leaks while you're filling it. If no leaks are found take it for a test drive and check the fluid again.

2004 Buick Lesabre uses quart of oil in 3K miles. Is this normal?


No it's not have your engine check for oil leaks, also have then do a wet and dry cylinder compression test this will let you know if you are burning oil, also have them check the spark plug's.Hope this was helpful.

I have a 1998 Buick Lesabre that keeps losing antifreeze.


Buick 3.8's are notorious for intake manifold leaks. If you are sure you are not leaking externally (look under the alternator and on the top of the transmission), it could be an intake manifold leak. I've replaced mine...I didn't think it was too hard a job for an amateur.
It could also be a head gasket, but the intake leaks are much more common.
