Lower rad hose? Entropy rad and truck water pump

I'm trying to fit the lower radiator hose I need for an entropy (swap) rad and a truck water pump. I saw on another thread it was a 20687 but it didnt fit (too long, angles wrong). Anybody have another hose I can try?

Thanks

Re: Lower rad hose? Entropy rad and truck water pump

I assume you have a LS swap...on my lower hose I never did find one that fit....I took 2 hoses and a aluminum sleeve and made one. ..

Check out my build thread I have a part number for a hose that worked for me. I did have to shorten it but it worked great. I believe the 5th gen Camaro and truck WP are the same.

Yes....with the truck accessories.

i thought the swap radiator would have the lower hose positioned the same (or very close) as a stock newer truck

I found it in your build thread. Looks like a Ford application hose.

I played around some more with the one I got and got it good and stuck on the water pump. So stuck I had to cut it off. Since it was now non-returnable I messed around and got it to fit by cutting off both ends. It's actually a tiny bit too short. I might buy another of the same one and trim it a bit more carefully. It was NAPA PN NBH7460.

I used a NAPA 9131 with the truck pump and entropy radiator. Had to trim some of the hose to fit but it ended up fitting great.

Re: Lower rad hose? Entropy rad and truck water pump

Are the hose fittings at least the same size?

That looks like it might be a better fit than the 7460 I have on there now.

thanks

Yes, fitting on the entropy radiator and water pump are the same.

No worries, give her a shot. I went through the same dilemma and had a pile of hoses to return to Napa

Ends up that this hose is way too short for my setup. Your engine must be mounted a lot further ahead than mine. I've got mine as close to the firewall as I could get it.
