Your car is starting to overheat or your thermostat is going out. Get it checked.
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
Mine was a bad ground on the gauge. Easy check by any certified mechanic.
Possibly a leak in the coolant reservoir bottle.
if the temperature goes up on ur gauge but it is not overheating means ur thermostat is no good
you could have abad temp sensor
Start with the fuses, then go to the more complex problems
Is it smoking a lot? If so you probably have a blown gasket. If it's not smoking, check the thermostat. I don't get how a car could be not getting hot but using a lot of water and the temp gauge is going up. Have you checked for leaks?
A signal from the temperature sensor on the engine.
Sounds like it could be a bad thermostat - not closing to allow engine to heat to normal operating temperature
well your car needs a new body kit because that contributes to the temperature of the car
This is probably an indication that your thermostat is stuck open. Go to a radiator shop and ask them to test it.
probably warming up...if the temperature goes above the average level, then your radiator might be low on water and coolant or the cooling fan is not working..
