Description
Predator HD F04-6006-PHD is a 2.5″ inside-diameter, 90-degree silicone radiator hose elbow for the upper coolant circuit on Kenworth and Peterbilt Class 8 trucks. Built from premium silicone rather than conventional EPDM rubber, it offers higher heat resistance and a longer service life than the OE Paccar F04-6006, and crosses to World American WA911-05-2578, Newstar S-26031, and Gates 28212.
Signs You Need a New Radiator Hose
- Visible cracks, splits, or bulging at the elbow
- Coolant leak at the radiator or thermostat housing connection
- Soft, spongy hose that collapses when squeezed cold
- Overheating under load due to restricted coolant flow
- Stained or weeping clamp seal
