Re: lsx radiator hoses
4th Gen V6 hose for top and '90 F-250 lower hose. The lower one gets tricky, though, because IIRC it has to be for a truck w/out air conditioning and it has to be from Gates. You have to trim it a bit. If you search on here you'll find the exact part number; there are entire threads on it.

Re: lsx radiator hoses
I used an upper hose from a 3.4L 4th gen and the lower is a Mr.Gasket universal one. It fits great, doesnt touch anything and was 25 bucks from summit.

Re: lsx radiator hoses
I used a Dayco 71321 for the lower hose. It was a MUCH better fit than the previous hose (no clue which one)

Re: lsx radiator hoses
