What You're Actually Buying
This is a straight piece of 4-ply silicone hose, no bends, no molded shape - a 3ft stick you cut to length yourself. 2.25" ID is the sizing that matters here; it's used all over Kenworth W900/T800 and Peterbilt 379/389 cooling systems wherever a straight radiator, surge tank, or heater hose run calls for that diameter.
Because it's straight stock and 4-ply reinforced, it handles the heat cycling and pressure of a heavy-duty diesel cooling system better than a single-ply rubber hose off the shelf at a parts store. Guys use it for radiator-to-block runs, surge tank feeds, or splicing into a longer factory hose that's only bad in one spot.
F02506S352 is the part number floating around on some Kenworth/Peterbilt parts lists for this exact stick - straight, 2.25 ID, 3ft length, 4-ply.
Why These Numbers Cross
D10302585, 24836, H42-225, and 57236 all reference the same straight 2.25" ID 4-ply silicone hose stock - different suppliers stamped their own part numbers on what's functionally identical bulk hose. Since it's straight stick material with no molded fitment, the cross-reference is about matching ID and ply count, not matching a specific truck's routing.
Where this bites people: some trucks run 2.25" hose in one spot and something close but different - 2" or 2.5" - a few inches down the line. Measure your old hose ID with calipers or a tape measure around the inside, don't eyeball it. A quarter inch off and the hose either won't seat on the barb or it'll be loose enough to leak under pressure.
Also check ply rating if you're replacing factory hose - some trucks came with 3-ply from the factory and upgrading to 4-ply is fine, but don't assume; confirm against your old part or your VIN-specific parts breakdown before you order.

Frequently asked questions
Does F02506S352 fit my 2015 Kenworth T800?
Probably, if your factory hose in that spot is 2.25" ID straight run - but confirm by measuring the old hose or checking the parts breakdown for your VIN. Truck configs change hose routing more than people expect, especially with different radiator or charge air setups.
Is this the same as the H42-225 hose?
Yes, H42-225 cross-references to the same 2.25" ID 4-ply straight silicone stock as D10302585. Different supplier, same spec - confirm ID and ply count match what you're pulling off the truck before ordering.
Can I cut this shorter or does it only come in 3ft sticks?
It ships as a 3ft stick and you cut it to the length you need with a sharp blade or hose cutter. That's the point of straight stock versus a molded hose - one size covers a range of hose runs as long as the ID matches.
