2005 PETE 379 overheating

I wonder if the radiator cap itself is bad.

I had a few bad caps that themselves failed the pressure test.

 

Do you hear when the eng fan turns on and at what temp does it start turning on to cool motor it may not be turning on at all and that will make truck over/heat fast?

 

Radiator plugged? Air flow.Will it hold a shop rag to the front with the fan on? Was this a gradual problem or sudden?

 

My truck has a two speed fan. So it turns constantly, sucking in all kinds of debris. Every spring I have to hose out the face of the radiator as it overheats when the weather first warmed up.

 

Fan kicks on for coolant temp @ 217 F. Code 61 is high coolant temp. I am guessing plugged rad or broken water pump shaft.

 

You replaced all of that but you didn't replace the one part it could be?

Replace the radiator.

This is your problem.

While your at it, maybe also clean your condenser.

I would also fire your mechanic.
