What’s up guys I have a 04 Tahoe 5.3 that isn’t warming to operating temp. The temp gauge always sits below a quarter I already changed the fan clutch like 3 times I ended up purchasing an oem acdelco fan clutch and still having the same issue I did run it without the fan and temp does rise and gets to operating temp I put fan back on and temp drops and stays the same I replace the thermostat as well like 2 times as well no change I have no idea what else to do at this point

change your thermostat

Subie0608

I did that twice already

mountainmanjoe

is the fan still coming on when it's not supposed to?

Isn't it winter??? Why is "only a quarter up" bad??? Anything within the gauge range is OK.

Are you relying on your dash gauge or have you verifed temperature? You may have a faulty gauge or sender. Is the heater blowing less heat as well??

mountainmanjoe

engine is supposed to reach operating temperature regardless of season. There's no such thing as "winter" engine temperature.

Subir0608: Welcome to the forum. Is it not reaching operating temperature after being driven for a while.
