I know that you can buy the rubber pieces for the heater hose assembly and replace those individually - can the same be said for the steam pipe?

Mine isn't currently leaking, but this will be the second time I've had it torn down in two weeks for coolant leaks, so I'm replacing all my rubber so I don't have to do it again. If anybody has a GM part number or knows of any other parts house I can go to to acquire that rubber hose chime in.

Probably even a longer shot than the first question, but does anybody have an aftermarket steam pipe?

Regular sources of parts such as Dal Slabaugh and Jason Cromer do not have this part. GM 10108635

 

You can get a regular small heater hose (forget the size) cut to fit and zip tie it out of the way

 

That hose is about 3/8" if I'm not mistaken. I'd have to use fuel line if I tried that route. I was wanting to retain the molded hose shape. Guess I'll just have to dig around and see if I can find another dealer that has the whole assembly in stock.

I went ahead and broke down and bought the heater hose assembly as well, might as well do everything if I'm in there.
