Lower radiator hose - part number?

cobrasnake · #1 (**permalink**) 06-05-2009, 10:47 AM

Looking to replace my lower radiator hose - primarily the one between the metal tube and block. I believe there is a single hose that is spliced with the metal tube. Does someone have a Goodyear or Gates part number?

Windsor block - SPF

Thanks - Tom

Call Justin at Hillbank and they will send you the factory SPF hose you are looking for. I have order several from Justin. I believe the part number is: (RH7391)

Or take the one you have to a local Napa (or other autoparts counter) where the attendant will let you go in the back and pull off the rack what might work. I do this all the time and locate the hose with the right diameter and bends, then simply cut to length. Also, I believe the lower hose has a steel coil inside to prevent it from sucking closed, so make sure you install that inside any replacement.

Good suggestions - I was hoping there was a particular hose that people used so I did not have to choose among the dozens of close ones at NAPA, Kragen, etc. The one I am looking for is 1¾" in diameter and has a 90º elbow - very simple.

Thanks for the reminder regarding the spring - you've uncovered why I a doing this drill

Tom,
Check out Gates part numbers: 21202 & 20910. Bill Meyers recommended those to me when I was asking the same question you were a while back.

Good Luck,
Dan

Here's an image of the 21202. Please let us know what works so that we can note that for future reference.

Thanks,

-Dean

I'm in agreement with ( RedBarchetta ) . This is a custom Item that must be matched at the auto store . Since the Dia. of the pump and radiator are different , I would take the hose pictured by Dean and take another hose at a sharp 90 Degree angle ( Dia. of radiator ) trim at Radiator and cut to length hose going to first hose and connect with a metal sleeve w/ clamps .
Just went through this . All went well .

I will post when I get a firm answer - the O.D. of the metal spacer pipe is 1.5" and the outlet from the radiator is 2.0" O.D. #21202 is 1.5 x 1.75" so that will be too small. #20910 is 1.5 x 2.0" so that seems to be the one that will be best, but also harder to find. Thanks - Tom
