What This Tank Is and Where It Bolts Up
This is the surge/coolant recovery tank mounted up front near the radiator core support on the Cascadia. It's plastic, molded with the fill neck, sight lines, and the mounting tabs that pin into the core support brackets. When these get UV-brittle or the seams start weeping, you'll see coolant loss with no visible external leak anywhere else.
It's not a pressurized cap tank on most Cascadia setups — check whether your cap is on this reservoir or on the radiator itself before you order, because that changes which tank you need even within the same model years.
Freightliner used a few tank variations across trim and cooling packages during this run, so don't just go by 'it's a Cascadia' — pull the number off the old tank or run your VIN before you buy.
Why These Numbers Cross and What to Check
A0532836000 supersedes the older 0532312000 and 0532313000 Freightliner OE numbers — that's a normal part-number update, not a different tank. Alliance lists it as N20 A0532836000, which is their aftermarket parts program number for the same fitment, not a separate design.
What actually matters on a coolant tank: overall height, the neck diameter and cap thread, the number and position of mounting tabs, and where the low-coolant sensor port sits if your truck has one. Get any of those wrong and it either won't seat right or the sensor plug won't line up.
If your old tank has a different number stamped on it than what's listed here, don't assume it's close enough — coolant tanks are cheap insurance against a hose blowing on I-5, and $199 beats a tow.

Frequently asked questions
Does A0532836000 fit my 2019 Cascadia?
Likely, but confirm with your VIN or by matching the number on your current tank. Freightliner ran a couple tank variants across the 2018-2022 span depending on cooling package, so don't guess off model year alone.
Is this the same as the Alliance N20 A0532836000?
Yes — Alliance is just carrying the same tank under their own aftermarket parts numbering. Same reservoir, same fitment, it's not a different design.
My old tank shows 0532312000, will this new one work?
That's the older Freightliner number this part superseded, so yes, it should cross over fine. Still worth checking your mounting tabs and sensor port location match before installing, especially if your truck's had any front-end work done.
