Re: Yet another heat issue

What does the temperature gauge show? Normal to get a ~50 degree drop in temperature from the head to the heater vents. If the engine isn't fully warmed up you won't get good heat.

Feel the heater hoses with your hand. Top hose from the thermostat housing should be hot and consistent. Lower hose return to the pump should be cool when heat is running, and same as top hose when not.
