Prevent a catastrophic roadside breakdown and keep your engine temperatures stabilized with this premium Volvo Mack Upper Radiator Hose distributed by FleetPro Parts & Tires. In the high-heat environment of a modern diesel engine bay, standard rubber hoses eventually bake, crack, and fail under pressure. This molded EPDM hose is engineered specifically to withstand the intense thermal cycling of the Volvo D13 and Mack MP8 platforms. Manufactured by Automann to rigorous Fleet Standard specifications, it features a custom-molded shape for a perfect, "no-rub" installation. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel shops, and owner-operators nationwide.

Durable Cooling: The Volvo Mack Upper Radiator Hose Advantage

This Volvo Mack Upper Radiator Hose leaves absolutely no room for fitment guesswork.

Unlike universal "flex hoses" that can kink or collapse, this molded unit is reinforced with a high-strength 1-ply aramid layer to maintain its structural integrity even under maximum cooling system pressures. It provides a direct, leak-proof connection from your thermostat housing to the radiator.
