Hey everyone, I'm in the process of changing my radiator due to the surge tank nipple breaking off in the hose. But on the new radiator I got, something isn't right. I know it's the right radiator, but the lower hose flange is 1 3/4 inch on the new one, and the old one is 1 1/2. So it doesn't fit. The new lower hose I got for it is also 1 1/2. The only hose I found that actually measures 1 3/4 is direct from Ford. Anyone else done this? The lower hose is a PITA to take off the block, and I don't want to if I don't have to. The two radiators are identical, except for that one small detail. And the hose I ordered fits the old radiator and is the same hose that's on the truck now. But the new radiator measures 1 3/4. Everything else fits perfectly except that. Any help would be greatly appreciated. It's the 1" core thickness by the way.

 

2 choices - get a different radiator or different hose.

 

I'd go with option #1; different rad.

I'm not quite sure how option #2 would go with a 1 3/4" hose, when the truck's block is going to 1 1/2". Unless there's something else involved; like the new hose is 1 1/2" at one end and then gets bigger and goes to 1 3/4" on the other end.

 

Update: We stretched the 1 1/2" hose onto the 1 3/4" radiator. It was tight and I don't think it's coming off anytime soon. Everywhere I looked showed a radiator for that with a 1 3/4" outlet though.
