See the list →Western Star is the make almost nobody stocks properly, and it is one of the reasons this catalogue exists. We list 19 Western Star radiator part numbers covering 1995 through 2026 across 16 model designations — the 4900 series, the 4964, the current 49X and 57X, and the 5900 and 6900 heavy-haul chassis.
The 4900 is the backbone of the line and the one we quote most: 4900EX, 4900FA, 4900SA and 4900 EA all appear in the listings below, and they do not all share a core. These are logging, heavy-haul and severe-service trucks, frequently spec'd with oversized cooling packages from new, so the radiator in the truck is not always the one the base model shipped with. Reading the year and the specific 4900 variant off the listing matters here.
The 49X and 57X are the current-generation trucks, sharing a good deal of their cooling architecture with the Freightliner Cascadia platform — several of our part numbers fit both, and the listings say so. At the other end, the 4964, 5900 and 6900 parts cover the long-nose and heavy-haul chassis that stay in service for decades in Canadian resource work.
Every radiator here is OEM-spec — original core dimensions, tank configuration and inlet/outlet placement — so it drops in without modification. Prices start at $1039 CAD and reach considerably higher for the heavy-haul cores, which are large, low-volume parts. Send us the model, year and last nine VIN digits for a same-day quote.
We serve fleets and owner-operators across the GTA including Mississauga, Brampton, Vaughan, Milton, Oakville, Burlington, Hamilton, Pickering, Ajax, and Oshawa. Canada-wide shipping available. Same-day quoting on all applications.
We list 19 Western Star radiator part numbers covering 1995 through 2026: the 4900 series including 4900EX, 4900FA, 4900SA and 4900 EA; the 4800TS and Low Max; the 4964; the 5900 WA-WB and 6900 WC; and the current 49X and 57X.
Some do. Western Star and Freightliner are both Daimler Truck brands, and the current 49X and 57X share cooling architecture with the Cascadia — several part numbers on this page are listed as fitting both. The listings name every make a part fits, so check the Makes column. Where they differ, they differ completely, so do not assume.
Western Star builds in far lower volume than Freightliner or International, and many of its trucks are spec'd individually for severe service, so aftermarket suppliers carry thin coverage. That is exactly why we hold 19 part numbers for the make rather than treating it as an afterthought.
Western Star radiators on this page start at $1039 CAD and run substantially higher for heavy-haul and severe-service cores, which are large and made in low volume. Shop labour typically adds $300–$600. We quote the same day on any application.
Yes, but we will need the VIN. Severe-service 4900s were frequently ordered with oversized or high-capacity radiators, so the base model listing may not describe what is actually in your truck. Send the last nine VIN digits and we will confirm against the build record before quoting.
