Test gauge function with a mechanical gauge to get actual engine temp.
have you flushed your radiator or changed the thermostat it could be stuck
The thermostat on a 2004 Chevy Venture is changed by draining the radiator, removing the upper radiator hose, and unbolting the thermostat housing. The old thermostat and gasket can then be removed and replaced.
its 2009 you punk, why dont you buy something newer...you better of replacing yourself.
Hi there, if you have flushed any engine and have changed thermostate there are only two options that are left; (providing that there are no leaks) 1. the thermostat is faulty / 2. your water pump is broken and needs to be replaced
I did a manual flush on the heater core with water from a hot water tank. I flushed a ton of crap out but did have to end up replacing the water pump.
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
I suspect that either your thermostat is plugged with debris from the radiator change or that the thermostat was replaced backwards. The spring side should be towards the block.
How did you change the thermostat?
more than likely you need a new radiator for it, when you install it back flush the engine.
You might have bad actuator that opens and closes airways.
This question is not complete. . Need to know if you've replaced radiator, thermostat, hoses etc. Are you asking this question *after* yo checked the thermostat, changed, added or drained the system?
I have a promblem with that too, my car would overheat very fast, it was a faulty NEW thermostat. It still runs hot, I think I need a new water pump
