Engine hot turn ac off. heat gauge flatten out 160 fans stay on.


On my 2008 Chevy pickup, the temp gauge would show normal temp and all if a sudden would drop out down to 160 on dash. When this happened, the panel would show ENGINE HOT, AC OFF. I had this problem for months. To reset it, I would have to pull over, take the battery cable off to reset the panel. I finally did some research and found out that the thermostat was the problem! When you replace the thermostat, make sure you get one that is set at 195 degrees cause there are different set points and if it doesn't make temp, the computer automatically takes over to prevent engine damage. I went to Autozone and bought a Failsafe 195 temp thermostat and my truck hasn't had a problem since!

2004 Impala ls temperature dash gauge


fans came late on those car,like 212 and second fan comes on at 224,you reprogram it to come a lot sooner,,other thing is there might be gunk inside the block,and coolant has hard time to pass through,and staying longer than enough in block temp goes high,even tough the radiator is doing it's job,it is just coming out block lot hotter than it suppose to be,and gauge read the block not the radiator

How do you set the temperature to display in degrees F instead of degrees C? This on the Heater/AC control.

The cooling fans will not come on until 225 degrees. Normal temp is around 199-215. Sitting still in traffic most will inch up around 220 or so. When you turn ac on it turns the fans on and may cool down engine, Check fan operation.

It sounds like your thermostat has shat itself. Pull that out and test it in boiling water, they should open at about 90 degrees celsius, if it doesn't open in boiling water, its rooted. If that still works, then could be your water pump. Check all hoses for blockages. Hope that helps you.

Ac controls quit working blower fan is running on high all thetime. compressor is not working.


fan elays are under hood in black box by battery. 3 of them. 2 for high speed, 1 for low speed. Default is high speed when there is a probem.

Suspect maybe they shorted something out when fixing dent. Did they do any welding on the van? Connecting the cables to the body can sometimes send voltage where it's not wanted.
