I'm pretty certain the Engine heater in my truck is inoperable. I'm planning to replace it, although I'm wondering if anyone that has changed the OEM type has an tips or tricks? Also, is there somewhere that carries the OEM type that goes right into the block? I have checked with the local idiots at some unnamed national parts stores, and all they come up with is a heater which I would need to cut my bottom radiator hose for. Any help would be appreciated.

 

Cummins parts ?

 

i found mine on ebay
