I admit defeat!!! rad hose size.

[tbar123]

I've looked through all the TM's the best that I can and haven't found anything on the size of the upper radiator hose elbow #8 on page 3-155 of the Technical Manual. I would copy and paste the page but haven't figured that out either.So does anybody have a replacement number, or actually what I'm looking for is the inside diameter so I can get a metal tube to replace that entire rubber elbow completely.Thanks for any and all advice.

Would be of benefit to know what truck or at least series you are working with.

Dag nabit ,I knew I was forgetting something!!, 84' M923

Which motor, 855 or 8.3?

 

[tbar123]

855, which I think is same as the NHC 250!

 

[dilligaf13]

Correct, it's an 855ci Cummins NHC 250. I'll take a look at mine, when I get home tonight.

Here's the supply data, characteristics should be what you need.

I crossed the part # into my standard system and couldn't find a cross, but I didn't try very hard and I can't access the CAGEC info from home.
