Radiator Coolant Silicone Hose Kit for Ford F100 F150 F250 Bronco (1968-1979) All Engines

High-Temp Reinforced Silicone Radiator Hose Kit for 1968-1979 Ford F-150, F-250, Bronco (Bumpside/Dentside)

What it Does: Replaces degraded, factory EPDM rubber radiator hoses with multi-layer reinforced silicone to provide superior thermal resistance and prevent coolant-related engine failure.

The Stock Ford F-Series and Bronco Cooling Weakness

The original equipment manufacturer (OEM) rubber hoses found in 1968-1979 Ford trucks are susceptible to electrochemical degradation (ECD). Over decades of operation, the constant heat cycling of Ford’s heavy-duty FE, Windsor, and 335-series engines causes standard rubber to become brittle, leading to micro-cracking and internal weeping. This degradation often results in hose collapse under vacuum or catastrophic bursting under the high pressures generated during towing or off-road use. Furthermore, stock rubber is rated for significantly lower temperature thresholds, making it a primary failure point in aging cooling systems.

The Engineering Solution

This kit is engineered from high-grade, 4.5mm thick silicone, featuring a 3-ply nylon reinforcement core. Unlike standard rubber, this silicone compound remains flexible and structurally sound across a massive temperature range of -65°F to 500°F. The multi-layer construction provides an 85 PSI working pressure and a 245 PSI burst rating, far exceeding the requirements of a standard 13-16 PSI radiator cap. This ensures the hoses will not expand or soften under heavy load. The kit includes a full set of heavy-duty clamps, ensuring a high-torque, leak-proof seal that resists the vibrations common in rugged 4x4 applications.

The Ford Truck Standard

For Dentside and Bumpside owners, cooling reliability is the difference between making it home and a breakdown on the trail. This silicone kit is built for the high-torque, high-heat environment of Ford’s heavy-duty platforms. Whether you are towing at max capacity or navigating technical terrain, these hoses provide the durability and pressure tolerance required for long-term engine protection.
