Radiator for International 3200 4200 4300 (2002-2007)

Heavy-Duty 2-Row Replacement Radiator for 2002-2007 International 3200, 4200, 4300 (NGV)

What it Does: The replacement 2-row aluminum radiator replaces the leaking or clogged factory heat exchanger on 2002-2007 International 3200, 4200, and 4300 trucks to restore continuous coolant flow and eliminate severe operating overheating.

The Stock International 3200, 4200, 4300 Thermal Degradation and Fatigue

Factory commercial fleet radiators endure extreme torsional frame flex and thousands of thermal cycles under continuous load. Over time, the OEM crimped tank gaskets degrade, causing fluid leaks at the header plate seam. Internal deposits also restrict narrow core tubes, creating severe heat soak that drives high operating temperatures in the Navistar DT466E and VT365 powerplants, directly risking blown head gaskets and premature transmission wear.

The Engineering Solution

Engineered for high-duty-cycle vocational work, this direct-fit unit features a premium T-6061 aluminum 2-row tube-and-fin cross-flow core measuring 20-1/2 in H x 25-5/8 in W x 2-1/4 in D. The core is furnace-brazed to maximize heat transfer efficiency and prevent fin separation. Reinforced high-temp polymer end tanks resist pressure spikes and vibration cracking. It incorporates factory-located 2-1/4 inch inlet and outlet necks alongside an integral transmission oil heat exchanger to ensure direct hydraulic hookup to OEM lines without custom fabrication.

Frequently Asked Questions & Fitment Warnings

Does this fit the NGV 3200, 4200, 4300?

Yes, this is a direct fit for 2002-2007 International 3200, 4200, and 4300 trucks equipped with factory DT466E or VT365 platforms; always verify your existing radiator's core dimensions (20-1/2 in x 25-5/8 in) and 2-1/4 in hose neck orientation prior to purchase.

Do I need to bleed the cooling system after replacement?

Yes, thoroughly evacuate air pockets from the cooling circuit after refilling with the specified heavy-duty coolant mix to prevent localized hot spots and water pump cavitation.

The International Severe-Duty Standard

Medium-duty fleets require zero-compromise thermal stability under relentless payload demands and long highway hauls. This radiator matches factory dimensional specifications while providing the structural integrity needed to safeguard your powertrain through demanding regional delivery and commercial transport duty cycles.
