[QUOTE="Gilaguy23, post: 431520, member: 19498"] I was thinking you had already replaced the radiator but if you hadent yet thats good with all the crap in there floating around. Sounds like the heater core was or is possibly leaking thus the rusty firewall. It may also have just been loose clamps where the hoses connect. Look for coolant crusties on the bottom of the heater box inside the cab which would be a tell tale sign of leakage of if you smell coolant when the heater or defrost is on. You could bypass the core completely if need be, just jumper a hose from point to point bypassing the core. Not helpful with winter coming though. I cant see any down side to adding the flush and then running it or driving it a bit and even doing it a second time if need be before calling it good. That crud will not do a new rad any favors ya know. Are you getting a floating layer of that crud on top of the recovery bottle and in the rad, as in oil contamination?? [/QUOTE]
