Re: 91 YJ Heater problem
I just purchased a 91 YJ with the same symptom. The gage shows that the
engine is warming up but it does not blow any hot air. I topped off the
rad and overflow and then took it for a little ride, still no hot air.
Other posts mention disconnecting hoses and attaching a garden hose to
wash out any blockage. Mike, you definitely seem to be the man in this
forum. I am a newbie, but I can follow directions. I would like to try
to flush out these hoses to see if they are blocked. Do you think you
can provide me with some clear directions on this? It seems like a
relatively simply procedure, I just don't want to disconnect the wrong
hoses. Where exactly are these hoses located? Which end do I
disconnect? Thanks, I have learned so much reading your posts for about
a month. Thanks again - Mark

Re: 91 YJ Heater problem
Mark,
There was a post I read while researching the problem. It described
feeling the hoses to determine if the core is blocked. If it is
blocked, one will feel significantly hotter then the other. There were
also many people that warned that if you use too high of a pressure,
you will blow out the core.
Pick up a copy of a Chilton or Hayes manual. The graphic make it much
easier to understand what is described in the forum.

Re: 91 YJ Heater problem
I fixed the problem. It was actually a whole lot easier than I had
imagined. I unhooked both heater hoses (from the engine end) and
attached a garden hose (with an attachment), ran the water and repeated
on the other hose. There really was not much to it. I was expecting
huge globs of stuff to flow out, never really got any; I just waited
until it looked like it was just clear water flowing through the hoses.
Hooked everything back up and I had heat. Being a newbie, I was just
hesitant but it was really extremely easy. Thank you everyone for your
advice. This forum continues to teach me loads.

Re: 91 YJ Heater problem
Next time you are in there, run the hose through in one direction for
while, then switch the connection and flush in the other direction.
Betcha it takes 2-3 swaps to get it clear both ways. The crud just
migrates top to bottom or into the cores and it takes some patience to
get it all out.
