Customer Question

Hey Mike, I have a 2002 Nissan Frontier that I recently replaced the thermostat on. And am still having overheating issues. at idle the truck will heat up and the coolant will fill the overflow tank. I let the truck cool off and check the fluid in the radiator which is always low. I fill it and the same thing repeats
