01 stock. I have a leak front passenger side. looks like a hard line above the block heater cord. I looked at auto parts store computer and in their Haynes repair manual...no dice. Can anyone ID this coolant line, part #, anyone have pics of that side of the engine? Looks like a dealer part. The system will air lock and no heat. top off with coolant and back in business for 4-5 days.
please help.

 

Supply and return heater lines. Searched but no luck. Junkyard may have them.
