Sir it is dangerous to work your car while it heats up no matte if not reaches the top at least it will destroy the engine gasket
you`ill have to check the radiator cooling fan while the car is hot and near red
it could b the fan fuse or the fan`s electric wire is unplugged
of coarse you will have to check the water level when the car is cold and check the radiator cap if it releases vapor then it is only the radiator cap is need to be replaced and i think it is

Why is temp gauge fluctuating while driving car is not hot.


Check the coolant level. Sometimes when the coolant level is low, it will cause gauge fluctuations like you suggest, since air is getting into the cooling system. When air is in the system, it causes the thermostat to open and close frequently resulting is wild temp gauge swings.

Check the connectors at the PCM or ECU; lose ones could cause this problem. Something else to consider is to get the sensor from the dealership; many of these sensors are very sensitive and aftermarket ones tend to not be calibrated correctly.

Engine overheats,thermostat is good, water pump good, head gasket good


I have seen this before...as a matter of fact, it actually happened to one of my cars...the temp would get extremely hot then all of a sudden drop to the normal range...(like a stuck stat), I did replace the stat and the problem continued...I knew however that the stat was not opening at the proper time, because when it did, I could watch my temp hand drop to normal. The problem was air in the system...took a while to get it all "burped" out, now it works perfectly. Keep an eye on the coolant levels and the resevoir fluctuation. This was the defining moment for me, the resevoir level dropped suddenly, I refilled and the problem went away. Good Luck! I hope you find this to be very helpful!

Fluctuating engine temp a/c sends out cold air intermittently


Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.
