Radiator Hoses for Heavy-Duty Trucks & Equipment

A reliable radiator hose is a critical component in your heavy-duty truck or equipment cooling system. At Custom Truck One Source, we offer a robust selection of heavy-duty radiator hoses built for trucks, trailers, service rigs and equipment in demanding environments—engineered for high temperatures, pressure cycles and long service life.

Why a Quality Radiator Hose Matters

Radiator hoses carry coolant to and from the radiator, engine block, heater core or other cooling components. In heavy-duty applications, they face extreme thermal cycling, high flow rates, pressure spikes and under-hood abrasion. A properly designed hose maintains coolant flow, resists collapse under vacuum, avoids bursting under pressure, and extends component life. For example, one manufacturer notes their heavy-duty straight radiator hoses are built for “demanding applications in heavy-duty truck service.”

How to Choose the Right Radiator Hose for Your Application

When selecting a radiator hose for truck or equipment use, consider the following:

• Temperature & pressure rating: Select hoses rated for the maximum operating coolant temperature and system pressure of your engine/system.

• Material & construction: Look for hoses made of EPDM or premium rubber with multi-ply reinforcement (e.g., two-ply or four-ply) and designed for coolant, oil and additive-resistance.

• Fitment & routing: Verify the hose diameter, length, bend/angle configuration, mounting points, clearance to other components, and ensure proper clamp type.

• Duty-cycle & environment: For off-road, heavy-haul, high-ambient or high-cycle service, choose hoses rated for severe duty, constant vibration and thermal shock.

If you’re unsure which hose fits your application, our parts experts can assist with fitment matching, part-number cross-reference and routing guidance.

Maintenance Tips & Replacement Indicators

To maintain cooling system reliability and avoid unexpected failures:

• Inspect hoses regularly for signs of softening, blistering, cracking, collapse of the inner tube or visible damage.

• Look for coolant leaks at clamps, joints or along hose sections—indicating possible hose failure or clamp loosening.

• Monitor engine temperature or coolant system pressure spikes; if you see abnormal behavior, the hose may be degrading or failing.

• Replace aging hoses proactively during major cooling system service—especially if the vehicle sees high hours or severe conditions.
