International Radiators — OEM-Spec Replacement Parts for Canadian Fleets

International — Navistar — is the second-deepest make in our radiator catalogue, with 46 part numbers covering 1987 through 2021 and 86 model designations. That range matters with this make more than most, because International kept a very wide model line: highway tractors, vocational chassis, medium-duty straight trucks and school bus chassis all carry different cooling packages.

The ProStar is the volume highway truck, and it is the one application where reading the listing carefully pays off. ProStar cooling packages were built in both a high-temperature single-core arrangement and a low-temperature three-section arrangement, and the two are not interchangeable. Our listings name which is which. The same split appears on some TranStar and 7700 applications.

For the 9000 series — 9200, 9400, 9900 and their i-series variants — we carry the classic long-nose cooling packages that are getting harder to source new. DuraStar and WorkStar radiators cover the MaxxForce DT medium-duty and vocational trucks, and the 4000-series parts reach back to the 4700 and 4900 chassis still working municipal and dump routes across Ontario.

Everything on this page is OEM-spec: original core dimensions, tank configuration and inlet/outlet placement, so it installs without modification. Prices start at $798 CAD. Navistar part numbering changed several times across these model years, so if you have an old number or no number at all, send us the VIN and the truck details — we confirm fitment the same day.

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.
