How to delete the troublesome heater control valve on a 90’s XJ<\/h4>\n\n\n\n

My 1991 Jeep Cherokee had the fragile plastic heater valve. Not only can this valve break and leave you stranded, it is prone to leak at the valve actuator. I have replaced mine a couple of times already so this time I decided to do away with it for good.<\/p>\n\n\n\n

The factory manual shows that this valve is open in all positions except closed and full cold on the temperature control switch. In the later years, Jeep deleted this valve.<\/p>\n\n\n\n

I ordered hoses for a 1999 Jeep Cherokee. Gates 19038<\/a> and 19039<\/a><\/p>\n\n\n\n

I removed the old hoses from the engine and the heater core. The ones on the heater core were a but difficult to reach. And I had to be careful not to damage the thin heater core tubes when removing them. I removed the valve still attached to the hoses.<\/p>\n\n\n\n

I used pliers made for the spring clamps<\/a> and a hose loosening plier<\/a> to help get the old stuff off.<\/p>\n\n\n\n

I put some rubber lubricant on the inside of both ends of the hoses and slipped them in place and reused the old spring clamps.<\/p>\n\n\n\n

I then capped off the gray vacuum line that controlled the heater controller. I lost very little coolant swapping the lines and had no leaks on start up. The engine compartment looks much cleaner now and I have eliminated one possible failure point.<\/p>\n\n\n\n
