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.

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.

How to add refrigerants? To a 2000 buick lesabre.My car is blowing hot air it went from cool to hot. and now it just hot air coming out.

look for the fitting that is the smaller of the two and is attached to the line that is the larger of the two, this is the "low" fill side, add 2 cans of r134a freon each can is one pound the system empty holds 2 3/4 pounds of freon thats 2 3/4 cans.
I would buy 1 can of leak detector/freon combo and one can of dye/freon combo, if it takes more add a small amount of a third can that has an oil mixture in with the freon that would complete your systems needs the cheapest and fastest way possible.
If you want it done to the book then you need to have a certified A/C man vacumn pump down the system, replace the reciever drier, add freon and oil to fill the system and then check for leaks.
Happy Motoring!!

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.

If the oil light is on, Don't drive your car until you've checked the oil level .
The oil light is an indicator that warns you when the oil level has dropped to an unsafe level and will not allow proper oil flow thru the motor because the oil pressure is dropping.

Don't take a chance! Check the oil level. Make sure it's between the full and add 1 quart line. If you don't see anything on the dipstick, it's really low... If you run your car with low oil, you're going to freeze up the motor.

If the oil level is ok and the oil light is still on, have the pressure sender checked to make sure there's proper oil pressure. The light will stay on if there's a problem..
