What This Hose Is and Where It Lives
This is a 0.75" ID molded heater hose, meaning it's pre-shaped at the factory into that P-bend rather than a straight piece you'd have to force into position. Molded hoses like this hold their shape under heat and vibration a lot better than trying to bend a universal hose to match - which is why Freightliner spec'd a molded piece here instead of letting techs improvise.
It routes heater coolant on Cascadias equipped with the Detroit Diesel DD13 or DD15, feeding cab heat off the engine's cooling system. Because it's molded to a specific bend radius and length, a generic straight hose or the wrong molded shape will either kink, rub on something under the hood, or just not reach - none of which you want to find out after you've already got the old one cut off.
Why These Numbers Cross and What to Check
05-28189-000 is the Freightliner/Detroit part number, and F02513S352 is another number tied to the same physical hose - different catalog entries, same molded piece. The 561.46189 listed under 'Unknown' looks like it could be a supplier or bin reference number rather than a competing brand's part number, so don't lean on that one to confirm fit - use the Freightliner numbers.
Since this is a molded hose and not a cut-to-length universal, there's no wiggle room on bend angle or overall length the way there might be with a straight radiator hose. Pull the number off the old hose itself if you can still read it, or check your Cascadia's build sheet by VIN, before you order. A hose that's an inch off in either leg of the P-bend either won't reach the fitting or it's got so much slack it'll rub through on something.
Ordering From PartStop
We keep this one in stock in Tacoma, so if you're a local fleet or an owner-op passing through and your heater hose picked today to blow, same-day pickup is usually doable - call ahead so we can have it up front. Ship nationwide if you're not close, and it goes out fast because nobody wants their cab running cold in February over a $25 hose.
This is a direct replacement for the Freightliner numbers listed, not a reman or a splice-it-yourself universal. Comes with our standard 6+ month warranty. If you're not 100% sure this is your bend pattern, snap a picture of the old hose and the number on it (if it's still legible) and we'll help you match it before you buy.

Frequently asked questions
Does 05-28189-000 fit my Cascadia?
Most likely if you've got a DD13 or DD15 under the hood, but Freightliner changed hose routing across model years and cab configs. Confirm by the number stamped on your old hose or by checking your VIN - don't just go off model year alone.
Is this the same as F02513S352?
Yes, F02513S352 cross-references to the same molded hose as 05-28189-000. Different number, same part - one's just catalogued under a different reference system.
Can I use a straight universal hose instead of this molded one?
You can try, but that P-bend is there for a reason - clearance around other components under the hood. A straight hose forced into that shape tends to kink or chafe over time. Molded is the safer bet if the old one was molded too.
