So for some reason my engine decided to overheat a bit and in the process ruined my heater control valve. This will be my third time replacing the Damn thing and im bloody sick of it lol. Does anyone know if there is a way to bypass the valve and just deal with not having heat? Also i read that the swb models don't have aheater control valve.....so Why do ext models have them but swb don't? plz give details if possible.
