Ever seen antifreeze look like this?

Jeep still runs fine just no heat.
Since this I have flushed the system and regained some heat.

I was just wondering if anyone has ever seen or dealt with this.

Blown head gasket?
 
Looks like stop leak and it has stopped up the heater core. Same thing happened in my daughters Grand. Had little to no heat,after checking it out found similar residue and the heater core stopped up.

Let me guess, XJ with an inline six?

NOTORIOUS for the Impeller blades on the Water pump to disintegrate. Pull the water pump and see if you have any fins left. It would account for the overheating and the rusty sludge.

a buddy of mine is battling this with his XJ now. even the new pump impeller blade rusted away in a matter of a month. I'd love to know if anyone has a permanent cure for this.
 
That looks nasty, I'd flush the sys again and pull the heater hoses and flush the heater core out well. Them fill it with clr and let it sit over night, my buddy did this on his xj, he went from no heat to a decent amount.

Yeah i created a pump between the heater core hoses and just pumped superclean through it, it warmed up but 2 hours down the road it got a little cooler
 
Try to flush the block out without washing all the crud back thru the heater core and radiator.


Flush the core till it is clean. Flush the radiator till it is clean. Bypass the heater core by connecting the 2 hoses together. Drop the rad hose that goes to the radiator. Leave the hose on that goes from the radiator to the water pump. Fill the radiator with water/cleaner. Run the engine while keeping the radiator full from the water hose.

Did this on my yota and it worked great.
 
I had this in my old CJ. The previous owner had used radiator stop leak (Meant to plug holes in radiator, also clogs up everything else...). Looked like vanilla pudding. If you completely flush the system, you may notice a leak in the system somewhere, as the stop leak has a usable life just like any mixed compound. A good system flush cleaner (as mentioned above) will really help out. For me, it took a couple hours to get everything good and clean, as that junk was caked up everywhere. I then ran a garden hose into radiator, and flushed it with clean water for another 10-15 minutes, then flushed the city water with distilled water for 3 cycles. Then re-topped up with coolant mixture. If you do notice a leak, there are better stop-leak compounds on the market today that are meant to be used then driven for a few hours, then the system flushed again with new coolant to make sure the mixture is only in the cracks/holes.
 
The radiator on my Ranger used to look a little like that.
Flushed the radiator & heater core 3 times each & had to replace the water pump (worn/corroded impeller blades)...had heat after that.
 
Be sure not to leave straight water in it.With temps droppin the next few days you might wind up w bigger problems than a dirty rad.
 
Less than 100k on this Buick, and the pipes looked like an 80 year old porkophile's arteries. And, of course, GM put it in everything. If it wasn't the gaskets, though, it would be something else. There was also a dozen unrelated oil leaks, a bad FSU, and a huge vacuum leak. The coil packs, surprisingly, were still good, but everything on that car seems to be held in a tenuous balance.
 
not sure of the coolant path on your xj but on other vehicles ive taken the hot heater core-water pump line off and got a hose fitting with a barb fitting and clamp it on the undo the lower radiator hose pour some purple power in before you connect the hose then turn the water on full blast till it comes out clean. you can also use cascade dish soap in the complete system drive around 20-30 min and take off the lower rad hose and repeat till its clean. the cascade method is used by cat cummins and detroit it works very well
