My buddy and I decided to do a cooling system flush on our 2000 XJ's, 215K and 15OK mileage. I had been reading about Rydlyme for outboards and thought it might work good on our Jeeps. So we rigged up a marine transfer pump to pump into the water pump outlet and ran a hose from the exit of the heater core into an oil pan we used as a sump.
We ran the solution at 50% for three hours and had pretty dramatic results...large amounts of fine rust down the driveway, plus larger sediment in the sump pan. We were surprised how well it circulated throughout the whole system, lots of pressure on all the hoses and out the radiator cap.
I can tell my temp is more stable and the Jeep runs noticeably cooler on the highway. However; my buddy has a ScanGauge...on the trip to my house, he was running 206-210 on the highway at 70mph. On the trip home, he was running 193-196 at 70mph....pretty cool we thought.
Anyways, here's some pics of the pump set up, the catch pan, and my driveway after the flushes.

And a link to Rydlyme...btw, it is 24 bucks per gallon, and we each used a gallon.
