Final resolution Cooling issue C-5
Posting final fix for cooling issue on my 2004 C-5 with 80,000 miles,
Started with temps going up to 255..
Replaced radiator, water pump, thermostat and housing, new thermostat. Flushed system. All new belts and hoses.Cleaned out any debris. Replaced failed drivers side cooling fan...
STILL getting too hot..
Chevy tech did a chemical test.. showed exhaust gases in coolant.
Diagnosed blown head gaskets.... Not bad but test did show it.
Replaced both head gaskets...
Cooling problem fixed.
