2007 powerstroke just had warrenty repair on egr & oil cooler noticed before repair heat in cab would die down (lack of coolant) after repair coolant level is good but still have same problem.

This happens after truck is run for 5 to 10 mins. truck will have heat but I get to red light heat cools down. Start going again cab heat comes back also if I pull a hill the heat will cool down and come back after pull. by now I have traveled 15 miles and am up to temp.

Any suggestions?

 

welcome to diesel bombers and what is your coolant level

 

welcome to diesel bombers. u need to post this in the ford section, or in the diesel in destress forum instead of the initiation. im not positive on whats wrong, but there aree a few pretty smart ford guys on here, and couple of ford mechanics. good luck

 

Post it in here Ford Powerstroke 03-07 6.0L - Diesel Bombers But it sounds like a bad thermostat in the engine ($30 or less) or after that check the water pump.

 

 

Hope you get your issues resolved!
