Question about 2003 Chevrolet Blazer

Overheating in my Trialblazer (2003)

Dear Experts,
Help me identify what would be the cause of overheating in my trialblazer? I suspected the fan clatch and changed, malfunctioning of the thermostat and replaced it. But still my car is overheating. What challenged me is the overheating will be sever while accelerating. When driving above 60miles/hr, it gets hot faster. If the engine runs at partking even with the AC on, the heating willnot be that serious. The atmospheric temp reaches 100-120 degrees.
Advise me with what would be the cause of this problem.

2003 suburban overheating when aprox stop in trafic for 10 minute


how hot does the temperature get? if it's just above the usual this could just be a different thermostat that the one you had before. If it is getting too hot, especially at idle, I would recommend checking the fan clutch (for mechanical fan) or the electrical fan operation, if the electrical fan doesnt come on, check fuses.

We have a 2002 chev trialblazer that dies!


First have codes checked (most larger parts houses do this free. Buy a chiltons or haynes manual and check code meanings and instructions for testing using a digital volt/ohmeter. Test when its running and test when it will not start and compare readings. My guess right now is either the throttle position sensor , map sensor or idle air control valve has a problem, but even if it was mine, I would not replace anything without testing.

El vacío se utiliza para cambiar el flujo de aire a los respiraderos. Suena como usted tienen una manguera de vacío floja o disconnected en el lado trasero de los controles.
