when i start my car and let it warm up, the heater stays cold until i start diving then it heats up almost instantly. anyone know what might cause this?
has someone ever installed one of those restrictor valves inline in the coolant tube going to the heater core? i know some early 90's rangers and explorers came with them from the factory. and ive seen a few in mustangs. they where most likely aftermarket but ive seen them. sorry for rambling.
