Under the relay cover should tell where they are. you could switch one with another next to it to diagnose. then maybe ck cooling fan itself by unplugging and powering it up manually with power and ground to connector. could even be coolant temp switch ocated on engine. is the engine lite on?

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.

My 2000 buick lesabre is running hotter than usual....looking at the motor i see water leaking from the top of the water pump, right around the intake

An intake gasket leak is a very common problem on the engine in your car, get it replaced and go from there. Be sure to check/change your oil. If it is milky looking, then the gasket is leaking internally also. Hope this helps, TJ

99 Buick La Sabre-accelrating problem-fuel injectors?

It sound as though the car is overheating and maybe the mechanic did not properly blled the system to expel the air.
Air does not heat or cool in a pressurized environment and will read ok on the temp guage.Basically the air is plugging the circulation at the senders spot.
Call the repair shop and ask if it was properly bled.
