engine over heating, check engine lite on temp gauge in the red. its okay around town, but over heats on hiway
coolant full, changed thermostate, fan functioning fine. had cooling system flushed. water pump not leaking. what have I missed
A cylinder head gasket fails due to excessive heating. Did you already bleed your cooling system? If not, start the engine and with the radiator cap off to avoid pressure build up and let your engine run for about 15 minutes. Then turn on your heater and turn it up to hot (it will help your coolant to circulate and push out any trapped air, refill coolant if needed).
