hi guys. i post this to see if anybody can help me with the problem. today was really hot outside, i went to another town to do things and when i parked the car i noticed the temperature gauge reached the red zone. i started it off and open the hood to check coolant level, it was lowww!!!!. like some mechanics told me before i refill some coolant with the engine running. it took time to reach the right level because was going up and down. its the second time it happened to me. there is another thing that happen to the car a few time ago. i see some leaking from the right lower side of the engine, when i took it to the car shop they told me its a bad valve cover gasket. can i relate the overheating or coolant fluid loss with that thing or is there anything else i can think about?
