I hope I am posting in the right spot. I have a 1997 Eldorado ETC, 108K miles. It had a crack in the radiator upper right side. I replaced the radiator and tstat, but, its still overheating after about 15 miles. I have flushed the block and new radiator, cooling fans work, pass over not plugged. I have run it with and with out tstat. I am at wits end. All I can come up with is the heater core (which shows on signs of leakage)
It has also developed a good miss, I think I need to replace a couple coils, no biggie, unless it is related to this.
Any help or advise is GREATLY appreciated.
