KODAK Digital Still Camera
AS I froze my ass off during this winter, I had a 97 Sport XJ and it had heat issues but they were only with the blower motor resistor. Michigan had a weird winter where it actually didn’t get extremely cold until about late January and early February. So while doing a gig job merchandising and driving all around, I had to have heat.
So while it was still cold as hell and we couldn’t break out the hose because it would become frozen, but we flushed as best we could.
Blue Devil Head Gasket Sealer update after 2k miles. Does it still work? These are our previous stories and an update on where we are today. We have now hit 2000 miles with Blue Devil Head Gasket Sealer working in the coolant system of my 1999 Jeep Cherokee XJ. We have seen all of the issues from the Heating and Cooling Thread resolved. The power has returned, the heat is hotter than ever before and there are zero leaks. We also replaced the entire heating and cooling system except for the heater core.
This product does work, my over heating issues are gone, the freeze plug situation has been resolved. I also don’t have the random stalling that was probably due to the bad alternator that was in my vehicle prior to this. We spent $600 to buy this 99 XJ originally, we invested a solid $350 on these repairs and have lengthened the life of this vehicle. Hopefully we can reach another 10k miles before we have anymore issues.
We did Alternator, Trans cooler install, new radiator, new water pump, new thermostat and ran the head gasket sealer. Why? We had over heating before this symptoms of head gasket leak including white smoke but no water or oil mixture. We ran water while testing all of this out as opposed to Antifreeze because we kept experiencing leaks. We also had to run a new lower radiator hose as this progressed on ward.
So that barely helped and then when I had extra money by a miracle my Water Pump went out and I had to with my dad brave the cold and actually do a proper flush. The best thing was that the weather broke and it was in the 40s, which allowed us to break out our hose and do a proper flush. CLR in the radiator and heater core busted out so much rust and rusty water flowed.
The biggest Vilnian in all of this was the heater core in let hose, it was rusted shut and there was zero coolant flowing in and out of the heater core. However, in order to get the part I went to 3 different auto parts store to track down the heater in let hose. So when the water that’s flowing through your radiator and heater core over 20 years starts to clot. Your heater inlet hose rusts and captures all of it and sudden forms a blockage and stops your heater core from being able to function.
First time flushing the radiator in my 99 XJ Classic, the Antifreeze looked like chocolate milk. Ran a antifreeze flush and still no hotter heat. Plan on doing a more in-depth flush and cleaning this week. Further more the heat seems like it’s just as cold if not as cold as yesterday and it’s extremely annoying.
o the next thing that we try to do is we decide to flush the radiator and go through that and start ro do that. As you can see in the pictures attached the antifreeze was black kind of and brown and all of it was nasty we ran a peak brand antifreeze / radiator flush kit we did that yesterday I only drove around like an hour and a half because it was cold and I bitterly cold driving out no heat so today we tried it out again no heat so I guess now we have to try this water pump fix and see what we can do from there.
