My car has always run a little hot in the summers, in town with the A/C running, but the past week and a half it's almost into the red.
I've flushed the radiator,, replaced the coolant and added "water weter", and checked the thermostat. Don't know what else to try.
Will it hurt anything if I put a colder thermostat in. Say a 180?
Any advice would be great. thanks.
