Why is my temperature gauge on C?
If the temperature gauge consistently shows the engine is warmer than normal, have your cooling system checked ASAP. There are many possible reasons that your engine is running hot, including low coolant levels, a clogged or closed thermostat, a failed head gasket or a water pump malfunction.
What does it mean when your car stays on C?
Reasons the Temperature Gauge Reads Cold If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken. Another reason the temperature gauge could read cold is if the thermostat in the vehicle stays open. If this is the case, the thermostat may need to be replaced.
Why is the AC off on my Chevy Malibu?
The high pressure hose is designed to increase and decrease AC pressure during different driving… It started an oily substance leak but oil level reads full. It soaked a piece of cardboard and gravel underneath in one night. Even though the level reads full, it could still be an oil leak.
Why is my coolant temp gauge not working?
The coolant temp gauge gets its input from the BCM and the AC gets told to do its thing there as well. You could have anything from a dirty connector (“fretting”) to a failed BCM.
Why does my car’s temp never go up?
1) coolant fan (s) come on when I start car 2) temp gauge stays on C (dead) 3) AC does not kick in (blows air with no AC) This happens at random as best I can tell. But when it happens, it might continue for a day, or half a day and then back to normal. The temp gauge is either dead cold or normal . . . never hot.
Are there any problems with my 2010 Malibu?
Had problems on 2010 Malibu but none with 2012. Seems like a poor design or bad elastomer on thermostat. Originally thought it was the temperature sensor and replaced it first but that did not fix the problem. Highly active question.
