There may be air trapped in the coolant system. the fans may not be connected since you had the radiator replaced. bring it back to the mechanic who did the work and tell him your not satisfied.he should be responsible for the discrepany.

I have the same problem with my 1999 Alero, I have done the same work as Kaynay1220 but nothing seems to do the trick! This morning my coolant hose exploded, causing my car to again overheat!
I'm getting rid of mine and buy a new car!

I have a 2001 Alero that is CONSTANTLY overheating. I've had it a year as of yesterday and barely put 3500 miles on it. It's been sitting in my driveway, not running. I've changed the thermostat, water pump, radiator hoses, had radiator work, head gaskets, coolant jug, etc. I constantly have air trapped in the system. My mechanic gets it out for me, but, it keeps coming back. I also hear a gurgle. Which I have no idea where it comes from. I've put sooo much into my Alero for overheating, I honestly don't know if there IS a solution!!

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.

The engine gets hot when it has been sitting in traffic for a while.


A couple of things to check. See if the fans are circulating on and off when it's hot. Are you losing coolant? Check for leaks on the overflow container, common problem on Alero's. Could also be a sticky thermostat, yet another common problem, or problem with water pump. Other than these few things, we don't want to think about a blown head gasket or craked head gasket, that's where it gets expensive.

OK you have done the engine side of things. If you have an electric radiator cooling fan make sure it comes on when radiator is hot, if not the fan motor is caned or the thermostat switch is faulty. Sometimes the fan motor is supplied by a fused/relayed circuit in which case these items will also need to be checked. Check that not only does the top hose from the engine to radiator get hot but that the bottom one does too. If not this would indicate a blockage perhaps in the radiator core due to sludge. If full of sludge give both ends a flush out with a high pressure hose. Like wise do the same with the bottom hose back to the pump. If the water is circulating and the radiator fan is working then the normal cooling system is working as it should. f the engine is running hot one last thing is to find the EGR valve and check that it is opening as it should. If not the combustion temperatures go very high. One indicator of a hot engine is blue/glazed spark plugs so take one out and check it for signs of hot running. If hot then look to clean the EGR valve and associated exhaust gas feeder pipe with frayed cable, cloth and and carb cleaner spray.

Have 99 alero heating up seems to be blowing all the cooling out the overfol on the surge tank can anyone help me


You may have a thermostat that is stuck closed. I would also check the radiator cap. Worse thing would be a blown head gasket.

My Alero keeps pushing the antifreeze back up and out where I poured it in. I changed the thermostat. But that did not help. What could it be? Thanks, Marlon


If you got the car hot you may have blown the head gasket especially if it's pushing it out whlie it's cold. Is there white smoke coming out wile cranking the engine? Is the water coming out while cranking the engine? I would say theres a good chance you blew the head gasket.
