Radiator for International 8500 (2010-2011)

Heavy-Duty All-Aluminum Radiator for 2010-2011 International 8500 (TranStar)

What it Does: The all-aluminum replacement radiator restores full heat rejection capacity on the 2010-2011 International 8500 to prevent thermal derate and catastrophic coolant loss under heavy hauling loads.

The Stock International 8500 Radiator Failure Points

Factory radiators on the TranStar 8500 platform typically feature composite plastic end tanks crimped onto an aluminum core with rubber O-ring gaskets. Over continuous heat-cycling and severe chassis torsional stress, these crimped seams separate and develop hairline fractures. The resulting pressure loss drops cooling efficiency, triggers ECM engine derating, and leaves the MaxxForce powertrain vulnerable to critical overheating during sustained highway and vocational operation.

The Engineering Solution

This heavy-duty unit eliminates failure-prone plastic tanks by utilizing 100% TIG-welded aluminum end tanks fused to a dual-row 48 mm (1.89 in) brazed core. Precision-manufactured 2.52-inch inlet and outlet necks ensure direct coupling with factory coolant hoses without custom routing. Pressure-tested to ensure leak-free integrity, this all-aluminum construction withstands cyclic pressure fluctuations, resists internal clogging, and delivers maximum thermal dissipation across severe duty cycles.

Frequently Asked Questions & Fitment Warnings

Does this fit the TranStar 8500?

Yes, this is a direct fit for the 2010-2011 International 8500 equipped with the MaxxForce 9 / 10 engine. Always verify core dimensions (35.24 x 40.55 in) and hose inlet/outlet positions against your existing unit prior to installation.

Do I need to bleed the cooling system after replacement?

Yes, technicians must drain the system, swap existing hardware and sensors, refill with fleet-spec coolant, and fully purge trapped air pockets before returning the vehicle to service.
