What This Hose Is And Where It Lives
This is a step-down CAC boot - one end's 100mm ID, the other's 85mm, with six molded humps in between to soak up engine movement and vibration between the charge air cooler and the intake side. Length is 184mm. You'll find this size reduction on Volvo D11/D13 and Mack MP7/MP8 applications where the factory routed a bigger pipe down to a smaller one before it hits the turbo or manifold side.
It's silicone, not rubber - handles the heat cycling and boost pressure a lot longer than the stock rubber boots did before they got hard and split. Comes with the correct hump profile so it doesn't collapse under vacuum or blow off under boost.
How The Numbers Cross
20760637 is the number you'll see on the truck or on the old hose. Volvo's own parts system also lists 20762524 for the same physical part - different number, same hose, happens a lot with Volvo/Mack shared parts since Mack runs Volvo-sourced cooling components. On the aftermarket side it cross-references to F02493S352 and 561.96524 - these are manufacturer part numbers from suppliers who build to the same ID, length, and hump spec.
The thing to actually check before you order: measure both ends of your old hose (100mm and 85mm), count the humps, and measure overall length. Silicone hoses in this family come in a bunch of length and reduction combos that look similar but aren't interchangeable. Don't just match on truck year - pull the old part or check your VIN-specific parts breakdown to be sure you're getting the right reducer, not a cousin of it.

Frequently asked questions
Does 20760637 fit my Volvo D13?
Likely, but confirm by pulling your VIN or checking the number stamped on the old hose - D13 trucks used a few different CAC hose configurations depending on year and cooling package, so don't assume by engine alone.
Is this the same hose as F02493S352?
Yes, F02493S352 is the aftermarket manufacturer number for this same 100mm-to-85mm, 184mm, 6-hump silicone reducer - it's built to the same dimensions as the Volvo/Mack numbers listed.
My old hose is cracked and I can't read the number - how do I know this is the right one?
Measure both ends with a caliper or tape - 100mm on the big side, 85mm on the small side - count the humps (should be six), and measure end-to-end length at 184mm. If those three match, you're in business.
