Radiator Flush gone bad, HELP!
My routine coolant flush has gone wrong somehow! I'm getting ready to take a roadtrip so was checking all my fluids. Found what looked to be a red muddy mess in the coolant tank so decided to flush the system. I've got the 5.7 with about 75k so figured it's about time anyway. Did a drain/fill/drain/fill multiple time until the radiator ran clean, then added a flushing/cleaning agent from the local parts store topped off with water then ran the motor for the first time. Got up to temp, drained more red fluid/ drained and filled multiple times and finally got her cleaned up. I filled it with PEAK antifreeze that advertises that it is good for ANY make model or year. Started her up when finished and it looked good. Ran to grab a bite to eat and it was running hot but I only let it get to 255, just barely to the red on the needle. Stopped let her cool then headed back to the house, only a couple of miles. Got up to the 250 mark again, parked and it was boiling like crazy. Let her cool down and now she won't even start! I'm getting scared by the posts about valve seats falling out but that might be my problem. Anybody have any ideas? I was supposed to be leaving on vacation Thursday but that may have just gone up in smoke! Any advise will be greatly appreciated. Chris
