No heat at idol
I have 07 Impala 3.5L no heat at idol. I have flushed
out Orange Anti-freeze And replaced with new
green. Bleed the System still no heat. Replaced
thermostat refilled and bled. I back flushed heater
core with garden hose still no heat. With Engine
return from heater core hose off no flow of
Antifreeze coming from heater core with Engine
running. No over heating of Engine?
