Upper rad hose for sbc with serpentine belt.
My apologies if this has been covered before, but I couldn't find the info when I searched.
So the upper rad hose didn't fit right on my 350 with a 92 Sonoma 4.3 accessory group. The hose was pushed tight against the alternator and very close to the fan. Figured there had to be a better way, so started digging through memory and catalogs. I came up with this: Thermostat housing for 84 G20 w/350 http://www.rockauto.com/en/moreinfo....045842&jsn=538 AND, Upper rad hose for 67 Firebird w/400 http://www.rockauto.com/en/moreinfo....402805&jsn=694 Truly plug and play. NO mods required and lots of clearance. Installed pic ( Please forgive all the fugly, making it work first. Pretty comes later. ) : |

Looks nice. Would a plain vertical water neck also work?

Re: Upper rad hose for sbc with serpentine belt.
My accessories came off an early nineties Camaro, and I used the factory 1969 C10 SBC upper radiator hose. The F body serpentine system positions the alternator lower on the engine.

Re: Upper rad hose for sbc with serpentine belt.
My truck came setup like this. The brackets were cut and pulleys cracked so it had to be replaced. Old 4.3 stuff is dirt cheap and everywhere...

Re: Upper rad hose for sbc with serpentine belt.
That's great info. Having the same issue. My real problem has been the lower radiator hose on the GM serpentine kit on my 72 350 sbc. Anybody have a part number or thoughts?

Re: Upper rad hose for sbc with serpentine belt.
I used the metal bendable kind and it worked out great on one truck. I cannot remember what I used on my other truck. But it is stock rubber I think.

Re: Upper rad hose for sbc with serpentine belt.
Yeah, I have been looking at all options. I purchased the R&D radiator out of Georgia. Its all aluminum so I removed the lower radiator neck and angled it so it would give me better clearance over the frame. Looking at early 90's truck LR hoses, and cut in a SS coupling.
I just am really hoping somebody has a manufactures molded hose out there.

If the neck is 1.5" and straight ( 73-87 style ) then you need a 73 hose. My truck had this when I got it. Hope that helps. |

Re: Upper rad hose for sbc with serpentine belt.
Thanks for the info! This saved a ton of time for me. Ordered the water neck and hoses from RockAuto. Water neck was in a box with the correct info, but the neck was no where close to being the correct part. Credit issued, ordered it off Amazon. Part was correct and is now bolted on.

Performing necromancy but this was very helpful in 2024 and needs to be pinned near the serpentine belt conversion posts.
