Rusted out fitting heater core to engine block
Hello F150 commmunity!
I was hoping someone would be able to give me some info and advise regarding my current dilemma.
I have a 1987 ford f350 crew cab with 351 cu 5.8 engine. Unfortunately I have a rusted out fitting located on top of my engine block towards the front. it goes directly to the heater core and I believe it's called the hot water return. The piece with the rusted out nipple also has two vacuum ported switches threaded inside it. And the whole assembly seems to be threaded inside the engine block. I was hoping if someone knows that name of this piece. I wasn't able to find it at my local parts store and I now believe it may be an old ford part. I would curious if a new nipple could be welded one in such a tight area. Any suggestions?
