I have a 2012 Kia Rio and lately it has been showing signs the car is overheating.
When I switch off the car and switch it on again it runs fine. I find this very confusing because it does it maybe once in 3 days. I took it to the dealer to have it checked and all the checks come back negative. Is there maybe some air trapped in the cooling system? I am suspecting this because I realized my radiator cap was old and replaced it. The other mechanic I took it to said the gasket is blown, but I don't see any symptoms that suggest a blown Gasket. Please help.
