Conversions & Hybrids - what radiator hoses for a body?

I lost the link I had on here, someone had part numbers for radiator hoses that work with the factory radiator and LS1 I believe

anyone have those handy?

thanks

am I mistaken?

What radiator hoses are you looking for?? Do you mean an F body?......title of thread is a little deceiving

What I did was bend some coat hangers to roughly the shape i needed and went up to the parts store and compared them with the wall of hoses. I am not near my car right now otherwise I would give you the part numbers I used.

A body, chevelle and such

I found some numbers on here with a search but they weren't as "definate" as the ones I seem to remember reading about.

One thing I'm curious about is that I'm pretty sure the outlet on the ls1 water pump seems smaller than the radiator

I just used a 98' Z28 Camaro Lower hose and with a little trim it fit ok..! don't recall that number but it was Goodyear hose..

The upper I also used a Goodyear, #26347x but added another hose of the same size in just a 90 Elbow to push the hose away from my CAI tubing. Else it would have worked without the 2nd piece added. I think it was also a 98' Z28 Camaro hose..?

Stock Tahoe upper and lowers fit my car just fine. I am using the truck water pump though... Maybe cutting a upper truck hose? Lower should work. Parts store, ask for a lower rad hose for a 2004 Chev 1500

Here's my setup:

Upper Hose - stock F-Body from P/S cooler to motor, 90 degree hose
from GATES (unsure of P/N) from P/S cooler to radiator
& trimmed to fit.

Lower Hose - Gates hose P/N 22437 (trimmed slightly)

Heater Bypass Hose - Gates hose P/N 42570187

Visualize your set-up from radiator to engine. Make a few measurements & write them down. Go down to NAPA or other, tell them you're doing a swap and need to pick out hoses for your application -- then go cross-eyed looking at the 100's of hoses hanging on their wall. We used several different hoses, spliced together for our swap. Works good!

The stock camaro hose actually has the right bends but its too small around, so I guess I'll just go look at something similar that fits my radiator outlet diameter and get that

found a lower hose

I'll post part numbers for what I find

Lower hose from a truck works great just needs a trim.

I think you are recalling my post for hoses I used in my 68 Cutlass LS1 project. They worked great. Check this linnk out for part numbers and pics:
