Since the last flush, I'm not getting any heavy deposits. Instead I'm
getting lots of fine powered rust. I pulled the heater core hoses and the
bright orange rust that was built up on the heater core and inside the
hoses is completely gone! :-)
Looks like another flush similar to the last one sh

When we did this we never had issues again - jsut make sure the it is the
correct size for the hose - and should be fine. For arguments sake - you
could make the Radiator the highest point by bleeding the system on
jackstands as high as you can safely get the front of the jeep.

Yes - 4.0. The heater core hoses do run at valve cover level, higher than

but I am hesitant to splice hoses because in my mind more fittings mean
more potential sources of leaks and failures. I'm hoping most/all of the

Sorry - coming on to this thread a little late - but guessing were talking
about a cherekee with a 4 liter. It is a very difficult cooling system to
bleed - for some unknown reason - a heater hose runs across teh top of the
engine - best I can remember. The only way I have every been abel to

heater cores seem to collect crud, regardless of where it originates
from. until you have an effective flush of that area (read; under
pressure), it's hard to eliminate that as an area of concern... and if
you didn't do your fill with the heater set full-on high so that the

Most likely your heater core is copper, or possibly aluminum.
I had a similar situation on a W126 (300SD) I once owned.
When I bought it the owner had just put a radiator on it within the =

My Dodge heater core wouldn't put out any heat at all. I backflushed it
with a garden hose for ten or fifteen minutes and the heater then worked
well until it went to the crusher.

I have thought the same thing. After I replaced the thermostat/flushed the
system I poured water in the upper radiator hose (connected to the
radiator) until water came out the thermostat housing. What I'm not clear
on is how does a heater core get rusty? Are they made of steel or iron
since your observation is that most of the crap is in the heater hoses,
odds are that your cooling system isn't getting fully filled, and the
air in the system is rising to the highest point (the heater core) and
causing corrosion there.
replacing the heater core in an XJ isn't fun.

That is what I am thinking.
Some of the black grit I've found in the coolant may be the old head gasket
from when I paid a mechanic to R/R the head. The Jeep had a weird severe
misfiring problem that turned out to be low compression from faulty exhaust
valves. I believe it was isolated to 2000-2
Air causes the rusting, so maybe if the whole thing is not absolutely
full of coolant then whatever is left exposed will rust. That would
most likely be at the top.

I considered that, but here's the kicker... Only the lower hose has the
spring and if I try to clean it, it returns to black which seems to be the
way it came from the factory. I don't think the spring itself is rusting -
it seems to be a surface that rust collects, but that's it. I didn't try

Maybe those springs?

Remove a sample from the radiator and another from expansion tank to compare

I think your flushing method failed.

I don't think there is an oil leak into the coolant. There is a small
amount of black stuff in the expansion tank, but it doesn't look like any
oil in coolant I've ever seen. It settles to the bottom, unlike oil which
would normally float, and the expansion tank rinses out with tap water.

About a month ago I was in town and rolled the windows down. I smelled
antifreeze and someone pulled up next to me and said you're leaking
coolant. My coolant jug was overflowing, but my dash gauge was spot on. I
got it to a nearby Wal Mart where I could buy supplies and rent a car
nearby.
