It could be that your heater core is blocked. I would suggest getting the cooling system flushed, and get a mechanic to see if there is blockage.

Sounds like the water pump is cavitating . Replace water pump. Check coolant level also. Open the bleeder valve usually located on thermostat housing to remove air from system. close valve when coolant is present while filling. close radiator cap and top off recovery bottle to correct level. These engines are prone to overheating, do not let temp gauge get in the red.

I can't give you any specifics on how to change your water pump, but I can answer your questions about the thermostat. Yes, the heat will work withou a thermostat. And yes, a car will overheat without one, especially in the summer months. The purpose of a thermostat is to allow cooler water to flow into your block, but also to allow the water adequate time to be cooled in the radiator. Without the thermostat, water is continuously cycling through your coolant system, getting hotter and hotter. Often I see people with malfunctioning thermostats jsut remove them, sometimes on the side of the road, just to get where they're going.

CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

Suspect you have a loose clamp on a radiator hose or the oil change guy made something leak. There is a tool which is similar to a a bicycle pump in that it pressurizes the water system and your engine does not have to run or be hot to test. Some major auto parts stores may have a loaner.

Its going to stay hot and lose pressure until you fix the leak.

2001 Olds Alero suddenly quits sending heat then sometimes it does and sometimes it overheats. Is this a water pump or a thermostat. Help. Mallory M


Check the cooolant level, sound like theres a leak somewhere, water pump, hoses, t-stat bad, rad cracked, heater core leaking, bad rad cap, cooling fans not working, you need to get it looked at really soon, before you get it to hot and blow a head gasket.

Car is over heating. Alero 2001


If you changed the hoses and thermostat and the car is still overheating, then the next thing to look at is the water pump. See if the water pump is leaking water from a vent hole. If it is, then the water pump is defective and will need to be replaced. Sure hope this helped.

I happen to own a 2002 alero, and alot of people says the same thing about theirs. You may need to replace you head gasket and run more antifreeze than water.
