Detailed Description

The Motorad T126 is an engine coolant reservoir cap designed to restore proper sealing and pressure control at the coolant recovery tank. It is manufactured with proper relief and vacuum valve function and quality tested for demanding automotive cooling systems. This makes it a practical replacement for Toyota Avalon, Camry, Solara, and Venza models that require a standard reservoir cap rather than a pressure-relief lever style cap. This part cross-references Gates T126 for the same application.

Common Problems This Part Can Address

• Coolant reservoir cap that no longer seals correctly
• Visible coolant loss around the expansion tank cap
• Damaged or worn gasket at the reservoir opening
• Improper venting in the coolant recovery system
• Service replacement for a cracked or deteriorated plastic cap

Installation Notes and Tips

Confirm the reservoir opening matches the cap diameter and push-fit style before installation. Inspect the tank neck and sealing surface for cracks, debris, or distortion, then seat the cap fully so the gasket can seal evenly. Verify the vehicle uses a standard, non-relief-pressure reservoir cap design before ordering.

Quality Assurance

Motorad manufactures this Standard line cap to meet OEM specifications and tests it for use in demanding cooling-system conditions. The cap is built with the correct relief and vacuum valve arrangement for the application, along with a pre-installed seal for consistent fitment.
