Water pump is brand new. I did it when I replaced the rad.

 

Btw, here are the steps I am going to follow for the renix burp:

Let jeep warm up, drive around until good and hot. Bring back home, back up onto driveway (it has an incline) and let it cool down. Remove temp switch, then tighten back down and start it up. Does this sound correct?

In the past I have done this with the jeep running and also I have done it with the loosening the reservoir cap. However, I read on another site with how-tos, that you are NOT supposed to remove the cap.

 

I read throgh most posts but not all of them. Just because you flush a core doesn't mean it's still not leaky or clogged or just bad from age. Change the heater cores and stop trying to find ways around it. In all the time you are trying to find ways around not fixing the core you could have done fixed it. They really aren't that bad. Just dive in there with a clear mind and do it. You will most likely fix the heat problems.

 

.....hence the importance of reading ALL the posts....

 

So.... I got some day light to work in today and I burped the system EXACTLY as was instructed (reservoir cap on, vehicle off, vehicle parked on an incline @ss end up higher than front). Loosened the temp switch and got a big hiss, some smaller hisses, and coolant proceeded to kind of spray erratically. This went on for a few seconds and the erratic spraying stopped and it slowed to a less erratic flow. I DID NOT completely remove the switch, just had it completely loosened and sitting in the hole. Once it turned into a more calm flow, I tightened it back down and started it up, got it up to temp, and now it sits closer to the 12 o'clock position (or dead center on 210). It still sits just to the right of 210, but not as far as its been.

Does this sound about right? Eventually will it just calmly pour out? Will it ever get to a point where it stops pouring out? Or am I merely looking for it to be a calm pour? Should I completely pull the switch out and let it spew until it stops?

 

Sounds like you got it man. Mine sits right at 205 now. Loosening the sensor should work, all you want is the air to escape. I would think if you took the whole sensor out, the chance for air to get back in would be there.
So all the heater woes are gone now?

 

Nah, not completely, but I think im on the right track. I think its just a matter of doing that stupid burping thing a couple more times and I should be good.

 

I have a problem with my heater blower not working on low & medium settings

 

I believe that sounds like a resistor pack problem.

 

thanks for the info but,now the blower was siezed.i took it out & freed it up so it spins.then i put it back in and does not work now.everything is plugged in.should i put in a new blower motor ? it's only 18 bucks

 

everything is fixed and the heat works great

 

Congrats. I think I did my final burp today. I heard no hiss, nothing, no pressure behind the coolant that came out either. No spurts, nothing, just kinda flowed out a bit so I tightened the sensor back down.

If this isnt the end, then its the end, because im fed up.

 

F it!!!! F IT F IT F IT! I quit on this stupid god damn thing. Ive spent at least double what I paid for the damn thing on fixing it up and still nothing. I still get crap *** heat. Anyone wanna buy an 89 xj? 800 bucks and its yours.

Ive replaced the rad, all coolant hoses, water pump, serp belt, t stat (x4), and heater core. Just to name the stuff associated with the heating/cooling system. Not to mention what ive spent on door seals, tires, and various odds and ends to fix the "nit noid" stuff.

F this peice of crap

 

for now, get a cover for the vents by your wipers. that is how we used to do it on our old hot rods because they didn't get good heat either. just block those vents and you won't get cold air mixing with your warm air.

the other thing, our 95 jeep had for a heating issue, is there was a big rust spot right where the wheel well meet the cabin, where that caulk sealant is supposed to be. i filled it with silicon and we never had cool heat again.

 

I guess the darn XJs just have cold "heat", no matter what we do.

Does anyone who bought one of these new remember if the heat was good then?
