so far ive replaced it twice because they both leaked out of were the linkage is unless I take of the vacuum line so is there a way I can delete it or do I have to keep switching them out

 

vac lines suck! no pun... if there is a way to do a vac delete, id go with that

 

you can get rid of it, just make sure the core flows the correct direction when you hook it back up. Later model cherokees don't have the valve.

The only kink in the process is you need to SEAL the vacuum line that normally controls the valve. I think you can find vacuum line caps at a auto parts store in the HELP! section.

 

Might need to replace old heater hoses with longer ones (5/8" & 3/4"). '97 & up XJs don't have the vacuum valve. As stated, need to plug the vacuum line.

 

but will I still have heat?

 

you might have heat coming into thye cab all the time if you eliminate it

 

All '97 & up XJs don't have the vacuum heater control valve.....the factory did away with it. Heater works fine in winter and no issues in summer.

 

well guess ill be doing that in the morning thanks

 

then why do 96 and older have a valve to stop the hot water flow because the vent system in the cab is different

well thats were I came up with the idea

 

i see were the one guy deleted his give it a shot see what happens

 

i actually just deleted mine today on my current xj. the previous owner had the heater core bypassed because of a cracked valve.

the last couple xj's ive done this on havnt had issues in the summer with A/C.

 

What's different?

 

there is no neat coming in at all without it, i dont have mine hooked up because the valve was leaking so bad and the last couple of days been kinda cold this far south dont have the money for valve i got hose in the shed looks like i get heat tomorrow for free

 

freedgr what are you running right now no valve?or somethings bypassed im confused
