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

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
Yes - 4.0. The heater core hoses do run at valve cover level, higher than
the radiator. I like your idea of modifying one of the heater core hoses,
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
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.

Last night I drained the coolant from the drain plug on the radiator. What

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
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.

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
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.
Ernest,
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
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.

Most likely your heater core is copper, or possibly aluminum.

I considered that the dark radiator has an effect on the coolant. The
bright green when in the radiator is almost clear in a coolant tester.
However, what's in the expansion tank is darker. The original problem has
been fixed. The flushing I did definitely helped. I'm not expecting 100%
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.

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.
On
Remove a sample from the radiator and another from expansion tank to compare
side by side; it's awfully hard to judge color inside a dark radiator.
Did you fix the original problem?
I think your flushing method failed.
