It has happened everytime i take off my coolant cap to check coolant level. the car heats up even after i add coolant. i make sure the cap is on tight. there are no signs that there is a leak until yesterday when i looked, the low fluid light went on. but there were, once again, no signs of leakage, at least while i was parked. what next?

Good afternoon,

It is possible the thermostat is bad causing it to run hot. It will also expel coolant out the tank.

I would start by replacing the thermostat.

Do the cooling fans work?
