PatO Posted February 2, 2011 Posted February 2, 2011 A little tech help please, I just replaced all my heater hoses and the heater valve which I broke when I was taking off one of the hoses to it. The heater valve has a vacuum assist operator on it. I had it apart for several weeks and now I can't the find small vacuum hose that connects to it. I may have taken it off but I don't have any extra parts so I think it is dangling there somewhere but can't find it. Can someone tell me where it originates from? A 91 - 4 liter; this is the black heater valve with the 4 heater hoses connected to it between the heater core and the engine. Thanks a bunch and back to Chilton's to see if I can find a diagram. Pat NEVER MIND, I found it, it comes out of the firewall above the A/C penetrations and is grey so it looked like a wire. All those little OEM heater hoses sections are pricey!
87Warrior Posted February 2, 2011 Posted February 2, 2011 All those little OEM heater hoses sections are pricey! Yes they are! I actually just did away with the little valve and noticed no change in cab temperatures. Plus the plumbing is cleaner.
ParadiseMJ Posted February 2, 2011 Posted February 2, 2011 All those little OEM heater hoses sections are pricey! My XJ has a pink hose, the MJ has a tan hose. I got all heater hoses for about $85, without the valve, which I deleted upon open conversion.
