Power by the Hour 5.0L Coyote Cooling System O-Ring Kit (PBH-612)
Stop coolant leaks the right way with the PBH Cooling System O-Ring Kit. Designed specifically for the 5.0L Coyote, this kit includes the hard-to-find O-rings that seal the quick-disconnect fittings on the upper radiator hose and the Y-shaped hose connection at the thermostat housing. These O-rings are not available from Ford separately, meaning you’d typically need to buy entire hoses or housings to fix a simple seal issue. PBH has sourced the exact replacements so you can restore a leak-free cooling system without unnecessary expense.
- Direct replacement O-rings for factory quick-disconnect and Y-hose connections
- Eliminates the need to purchase full hoses or thermostat housings
- Compatible with all 2011–2023 Ford 5.0L Coyote engines
- OEM-quality materials for reliable, long-lasting sealing
- Simple, cost-effective solution for common cooling system leaks
What’s in the Box:
- Upper radiator hose quick-disconnect O-ring
- Y-hose to thermostat housing O-ring
Note: This kit does not include the thermostat O-ring.
