My 99 alero keeps overheating but the coolant is full, and when i shut it off it starts gurgling what is wrong


Is the thermostat opening at 195 degrees ? Does the radiator fan come on at 220 degrees ?
The gurgling noise is usually air or coolant moving around in the system. If the engine is very hot this noise can be normal.

I have a 1999 Oldsmobile Alero GL Sedan that is overheating. Where is the problem?


check coolant level, make sure car have half antifreeze and half water,if coolant level okay, car overheating when starting up driving is faulty thermostat and radiator cap.if car over heat while sitting in long line of traffic.your coolant temperature sensor could be faulty, or coolant fan fuse blowed or relay failed.hot wire cooling fan if it works, problem is the wiring or pcm, if every thing working okay.check engine oil if look like milk shake or you have a lot white heavy smoke coming out the exhaust, you have a blowed head gasket.

Water is leaking out of my coolant container.car is overheating with less than 2 mins of driving


Need to seal the leak in the coolant container with epoxy or by replacing the coolant container.

Fill coolant system with 50/50 solution up to 2 gallons may be required to stop the overheating.

Don't drive an overheated engine.

My alero 99 was overheating now engine soon light came on


What you can do is go to a parts store like Auto Zone or most part stores and have them check the codes.This will help find what could be causing the light to come on.It could just be something that was disconnected or removed when the thermostat was replaced.Let me know what you find and I`ll be glad to help you out.Good luck.

Overheating, whitesmoke from tailpipe


I hate to say it, but it definitely sounds like you have a blown head gasket. Overheating and white colored, "sweet" smelling smoke are both telltale signs of this. If it started overheating first and the white smoke came after, then you will need to have your cooling system inspected after the head gasket is replaced.

White coloured engine oil, overheating


White oil means water or coolant is leaking in via Head Gasket Failure or a crack in the head. Along with repair - be sure to have each cylinder compression tested to see if there is a crack that has developed.
