What This Hose Actually Is
This is a 175mm silicone hump reducer, 2.5" on one end stepping up to 3" on the other, built to absorb engine movement and vibration where a rigid tube or straight hose would crack. Comes with two stainless clamps already in the box so you're not digging through a drawer for the right size.
On International/Navistar trucks running F02496S352, this is the factory-shaped piece - the hump in the middle isn't cosmetic, it's what lets the hose flex without kinking or collapsing under vacuum when the engine rocks on its mounts.
Silicone over rubber here matters because these hoses sit near the radiator and turbo piping where heat cycling kills regular rubber in a couple seasons. Silicone shrugs that off a lot longer.
Why the Numbers Cross
2030772C1 and 2024703C1 both point to the same physical hose - Navistar revised part numbers over the years without changing the hose itself, so you'll see both floating around parts books and old invoices. F02496S352 is the same piece under a different catalog reference.
What actually matters when you're cross-referencing a hump hose: ID on both ends, overall length, and where the hump sits along that length. Get any of those wrong and it either won't seat right or it'll rub against a bracket or fan shroud you didn't account for.
Don't just match numbers off memory - pull the old hose and measure it, or better yet check the number stamped or molded into it if it's still legible. That's the fastest way to confirm you're not ordering a hose that's close but not quite right.
Ordering From Us
We keep this one in stock here in Tacoma, so if you're local and need a truck back on the road today, you can grab it same-day. If you're not local, it ships same-day nationwide when ordered before cutoff.
Comes with a 6+ month warranty, which covers you against a bad hose out of the box - not against putting it on something it wasn't built for, so still confirm fit before you install.
If you're not sure whether F02496S352 matches what's coming off your truck, call us with your VIN or the number off the old hose and we'll check it against the book before you buy, not after.

Frequently asked questions
Does F02496S352 fit my International truck?
Likely, if your truck uses a 2.5" to 3" hump reducer in that location - but engine and cooling configs vary by year and application, so confirm with your VIN or the number off the hose you're replacing before ordering.
Is this the same as 2024703C1?
Yes, 2024703C1 crosses to this same hose - Navistar just reissued the part number at some point without changing the physical part. Same hump shape, same dimensions.
Do I need new clamps or does this come with them?
This one includes two stainless clamps sized for the 2.5" and 3" ends, so you don't need to source those separately unless you prefer a different clamp style.
