Please help. I am looking for part number ( and where to order) for the coolant hose that connected tfrom the rear of the engine and wit connect to the heater valve Thanks in advance

 

What number are you looking for? If you are speaking of the hose, which I call the octopus, you can get it at RockAuto. I just purchased one and they are fairly cheap

 

The hose coming off the rear engine block is pretty much straight.

Possibly replaced by a generic hose to be cut to length

 

Sounds like #16 if I had to guess. That has a special fitting molded into the outboard end to connect to the mating hose, also with a special end. I've bought one or two, don't remember where, though most likely were Uro parts. Possibly Rock Auto. Best practice would be to get the EPC from this forum and look up the part number, then scour the web for it.
