It looks like I need to pull my radiator and clean it more and try and open up some bashed in fins. I looked at it yesterday trying to see how difficult this is to do and I'm guessing all I need to do is unbolt the shroud and set that back and then unbolt the radiator and pull it up after draining the coolant. I presume there's nothing wrong with re-using the coolant either?

Pretty much, but it depends on whether you have an automatic trans or not. Also, might help if you tell us what Jeep you are doing this to...

i've been staring at the fsm for a while now trying to picture the difference between the ac condenser and the radiator. the call out figures keep flipping the reference as to which is which.

the radiator is the big radiator looking thingy where you put coolant in. the a/c condensor is the little radiator looking thingy that has freon running through it. the a/c condensor is located between the radiator and the grill. if you look at the lines coming off the a/c compressor and follow them, sooner or later they'll lead you past the radiator to the a/c condensor.

oh yeah.......don't forget to disconnect the tranny lines, and don't forget to check/top off the tranny fluid when put everything back together.

personally i wouldn't re-use the coolant. this would be a good time to replace it and have nice clean properly mixed coolant..

i would flush the coolant out out of the block as well. Take the t-stat off and spray water in there till nothing but clear H2O comes out of the water pump. Change the t-stat to.

the water pump and t-stat are like 6 months old as I had a bad fan clutch when I had taken it in for some other stuff and they fixed it because of a leak. I'm not really worried about the block and the coolant is pretty well new too although I'll probably put fresh coolant in. My concern is getting the mud I have yet to clean out of the radiator and fixing the fins. I also need to replace both tranny fluid lines into the cooler.
