Thats coolant that needed changing quite a while ago....
And if you have a burnt valve anyway, pull that sucker change the plug and give it a valve job. The shop that checks the head, should be able to pop the freeze plug right in.

The coolant has always been that color we flush it 5 times one week and it was still like that. Wait til I post a pic of the rad cap!!! I use well water. To cheap to use bottle. The water will be clear for a day or two then turns to rust red. also I'm broke so aint got the money for a valve job!

Good luck with your repair job. If nothing else, you'll learn a ton about the engine of your Jeep. Hopefully you'll also learn that sometimes cheap isn't really cheap in the long run.

I guess you're going to pay a lot more now than you would of had you used distilled water. All of the minerals in the well water has probably wreaked havoc on your entire cooling system. Add that damage on to whatever abuse the DAPO has put it through, and you end up with your heep on a trailer and a big repair bill.

We don't have a problem in none of the other cars/trunk we have about the coolant system and we run well water. Sometime you don't have money for the good stuff and when you do get it something goes wrong! we think its something in the motor causing it to turn red,IDK. But we are goin to flush her really good when we get her fixed. I think the red has built up in the bottom of the rad. and keeps causing it to turn red. The red is like a sludgie texture.

The red is from rust deposits sitting in both your radiator and cooling passages. Most likely ALL of your freeze plugs are close to being rusted through. By using well water, you not only increase the rust issue, but you also stand a good chance of having hard water deposits block a cooling passage which can lead to such things such as burnt valves, premature water pump failures, and blown freeze plugs. Besides which, distilled water is less than $2.00 (click for link) a gallon. It's just good insurance for your cooling system. There is nothing wrong with using a garden hose and well water to flush your cooling system, just be sure to use distilled/purified water to mix with you coolant.

Montana XJ is right.. The reddish sludge is from the minerals in the well water reacting to the metals contained in the block and cooling system. Well water is cheap. But hard water deposits can do some serious damage. Chances are your radiator passages are getting plugged also with this stuff, which will lead to radiator failure or more overheating issues.
I probably understand being broke better than you do. But fixing something correctly once ends up being cheaper in the long run.
