The radiator was replaced a year ago

 

There is a copper type stop leak out there that looks just like that, so my bad.

 

Just unhook both hoses and flush ?

 

well good new took radiator plug out and unhooked lower radiator and the rust disappeared within a little time like 30 secs and I could see clean water. Used water hose.

 

I would fill you entire coolant system with water. Put all the hoses and cap back on. Start up your jeep, turn your heat on, let it run for about ten mintues then flush it all out,

 

I would try that but the hole in the freeze plug isn't allowing much to be held. I just flushed the heater core took awhile for water to pass but when it did a little while later a dark milk shake section passed. Water is now clean. Those clamps are a pita to get off safely.

 

Brass is metal. Steel is metal. Aluminum is metal. Copper is metal. Gold is metal. Silver is metal. Uranium is metal, mercury is metal, and on and on and on. There is a whole list of elements (and alloys) that are metal.

Do you mean they are steel?



Nobody can tell you that for sure. It might be, it might not. You should probably find out before you start buying parts.

A compression test will tell you a lot, and there are test kits you can get that will check your radiator fluid for exhaust products. If the test is positive, your head gasket or head is toast.

Thanks gonna buy one at napa.

 

How does stop leak cause freeze plugs to go bad? Those pics look like years of owner neglect, no cooling system maintenance and no corrosion protection.

 

It creates a layer of mud over the freeze plug and just corrodes it. See in my pics. And definitely years of cooling system neglect.

 

A sealer that's corrosive doesn't sound right. Any iron motor without adequate corrosion protection will quickly develop "mud" inside.

 

It has always had coolent as long as I've owned it. I believe that I'm the second owner. Dealer replaced the radiator.

 

I'd do a compression check anyways. Definately before doing the plugs, because if you end up needing to do the head, might as well do em all at once since the manifolds and P.S. is pretty much 1/2 the work of a hg, and you already gotta pull them for the freeze plugs

 

Crap already taking stuff apart. I will do it when the plugs are done. If it is my mechanic says used blue devil something about liquid glass?

 

How do I get this off
