Detailed Description

The Motorad T142 is a standard engine coolant reservoir cap engineered for closed cooling systems that require a 2.32-inch cap diameter and a round profile. Its design includes relief and vacuum valves, a pre-installed gasket or seal, and indicator markings to support accurate replacement service. This part number T142 is used across multiple Hyundai and Kia models, including the Hyundai Sonata, Hyundai Genesis, and Kia Optima, where the cooling system calls for this specific cap style. The T142 also cross-references Gates T142 for the same application.

Common Uses

• Replacing a worn or damaged coolant reservoir cap.
• Restoring proper pressure control in the cooling system.
• Addressing coolant loss caused by a weak seal.
• Correcting vacuum valve or relief valve issues.
• Servicing a cap that no longer holds securely on the filler neck.

Installation Notes and Tips

Verify the filler neck inside and outside diameter before installation to confirm the correct fit. Inspect the sealing surface and reservoir neck for damage or contamination before installing the T142. Confirm the cooling system uses a closed, non-pressurized reservoir cap with the specified dimensions and attachment style.
