My 2003 olds alero keeps over heating. I have had a major tune up, changed the thermostat and its still over heating. The water pump is working fine. What else can it be?


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.

hi, i dont know about the dipstick, but your overheating problem is most likely to be the thermostat...sounds like its stuck in the closed position,not allowing colder water to circulate, hence the overheating.......needs changing

On mt 2003 olds radio, there are 2 "spots" on the upper right hand of radio facing. Undo a paper clip, fits nicely, and hold until you hear a beep, use this to change time after beep.

Average costs


The labor is most expensive part of this repair.
On the 3.4 L V6 engine, the labor should be about 1 1/2 hours times the shop labor rate.
If the 4 cylinder, then the labor is much higher due to the location of the thermostat.
