Well, I flushed and refilled the Cruiser (with the red stuff). 50 miles later, engine starts running hot and red stuff trailing behind the rig. Tried to refill the radiator, but liquid just runs out of the bottom. :'( Can't tell for sure, but probably the lower seam. Time for replacement - hope the head gasket survives! ??? I've read all the earlier posts and it seems the '93 3 core brass is a good choice. Is the all metal aftermarket even better? - Where can I find one? What are the odds that the head gasket needs to be replaced as well? BTW - '97 FZJ, basicly stock Thanks in advance for your help!
