  • Features
    • Our B-type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
    • Our deep extrusion header provides a stronger tube to header joint which is more resistant to the effects of vibration and thermal tube expansion, virtually eliminating tube to header leaks.
    • Our fin edges are folded for increased stability and heat disbursement properties.
    • Our included "multi-fit" attachments allow one radiator to cover multiple vehicle applications without sacrificing OE fit. This results in wider vehicle coverage with substantially less inventory.
    • Thermal expansion cuts allow for longer life and reduce failure rates by allowing improved core expansion and contraction during normal heat cycles.
    • We design and manufacture all our radiators to meet or even exceed Original Equipment specifications. We take pride in producing the most reliable replacement parts in the market.
    • We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.

When your 2004-2007 Chevrolet or GMC medium-duty truck needs a radiator replacement, Reach Cooling 42-10424 delivers an aftermarket solution engineered to meet or exceed original equipment specifications. This cross-flow aluminum-core radiator with PA66-GF30 tanks is a direct replacement for Active Radiator Supply Company 5800-43, and also cross-references 1-800-Radiator 2403348, Serck FLA000851, NAPA NR4210424, Paccar Parts RAD42-10424TRP, and OSC HD9160 - so if any of those numbers brought you here, this is the right part. It fits the full spread of 2004-2007 Chevrolet C6500 Kodiak, C7500 Kodiak, C8500, and GMC C6500 Topkick, C7500 Topkick across 7.2L, 7.8L, and 8.1L engine configurations. Reach Cooling designs features like centrally reinforced B-type tubes, deep extrusion headers, folded fin edges, and thermal expansion cuts into every radiator to reduce tube failure, resist vibration, and extend service life - the kind of durability fleet mechanics and owner-operators depend on. With included multi-fit attachments and construction built to OE dimensions, this radiator drops in correctly the first time, getting your truck back on the road with confidence.
