After driving the vehicle for a while the heat turns lukewarm to cool. If I stop or turn off the heat for a few minutes it may turn hot again but not always. Usually at idle it is hot but not always.
What I’ve competed thus far:
1) Bypassed heater control valve and plumbed heater core straight
2) Flushed heater core with CLR (water ran smoothly through) and radiator twice
3) Replaced thermostat twice
Any other suggestions would be greatly appreciated.
Thanks
