Thread: Radiator hose part numbers please

Tweet

I can't find my parts list-

32 roadster, Walker radiator set up for SBC, ZZ430 motor.
Someone have part numbers for the upper & lower preform hoses? Bottom one needs to have a internal spring to prevent collapse.
My lower one is looking a bit portly.

Appreciate any help.

On my 32 3W and the 32 roadster ( both with ZZ430 engines ) I use a Gates #20225 on the lower and a Gates # 20046 on the upper.



On the #20025 ... I have to shorten it up some and the end theat goes into the Walker Radiator has a reducer sleeve ( available from Gates ) . I do not have its number but any decent parts counter man most likely has it.

On the #20046 ... my thermostat housing goes straight up ...



It is a Everco #W-24931 but a 1985 Chevy van with a 305 will work also.



I have a screw in temperature gauge in the fitting on the thermostat housing since this photo

Thanks for the numbers buddy. Helps alot. Your bottom hose looks exactly like mine. My top one is close but my water neck is angled (and swivels).
I have a straight one around here somewhere.

Forgot about this thread- guess I should update.

So-Cal Speed Shop sells a Gates hose for the bottom. I got the number & bought it else where.

Bottom hose is the same Gates #20242 but comes with no internal spring. I robbed a spring from another hose I had laying around.
The bottom hose needs a 1 3/4 x 1 1/2 bushing at the water pump. Part is Gates #26391
Fits perfect w/ a little trim.

Upper hose, So-Cal sells the upper also but for a straight water neck. That number is a Gates #20380 but I decided to use my angled water neck because of my MoonEyes oval air cleaner. The straight one wouldn't clear- plus I have a passenger side inboard alternator to route around too.

Angled swivel base neck & a Gates #20607 w/ a bunch of trimming to fit. Perfect fit.

Hope this info helps someone else someday.

And it did. Thanks.

I used lower hose for 1956 chevy v8. worked perfect, no cutting, after spending hours trying to figure something out for it. got the idea from this board.
