Detailed Description

The Motorad T5R is an engine coolant reservoir cap engineered to meet OEM specifications for select Ford F-250 Super Duty and Ford F-350 Super Duty applications. It is designed for cooling systems that call for a 5 PSI relief pressure, including charge air cooling and secondary cooling system configurations listed in the fitment data. The Standard product line focuses on direct-fit replacement coverage for common service applications, and this cap follows that approach with a cam-on design and vented, pressurized construction.

This part cross-references Anchor 10268 and AP Exhaust 7505 for the same application. The T5R part number is also referenced as 9T5R and BC3Z8100A in interchange data.

Common Issues This Cap May Address

• Coolant reservoir cap leakage at the seal or valve area
• Loss of system pressure in a 5 PSI cooling circuit
• Improper venting or vacuum relief during engine cool-down
• Reservoir cap fitment concerns on Ford Super Duty cooling systems
• Replacement needs for worn or damaged coolant reservoir caps

Installation Notes and Tips

Verify the vehicle year, engine cooling configuration, and reservoir cap style before installation. This cap is listed for Ford F-250 Super Duty and Ford F-350 Super Duty applications with notes including charge air coolers and secondary cooling systems, so match the original cap specification to the vehicle’s cooling setup. Inspect the reservoir neck and sealing surface for damage before installing the new cap.
