Radiator Cap Adapter Overview

The Motorad 3037 radiator cap adapter is a threaded tester adapter for use with the 9300 and MT-300 cooling system pressure testers. It is built from metal for professional cooling system service and is used to test automotive coolant caps and system pressure.

Key Features

• Threaded adapter for cooling system pressure testing equipment
• Metal construction for durability in shop use
• Designed for coolant cap testing and pressure verification
• Compatible with Motorad 9300 and MT-300 tester systems
• Part number 3037 for easy identification

Detailed Application Information

This adapter supports cooling system diagnostics on a wide range of Volkswagen, Audi, Seat, and Porsche applications, including Volkswagen Golf, Volkswagen Jetta, Audi A4, Audi A6, and Porsche Cayenne coverage. It is a service tool component, not a vehicle-mounted part, and is used to connect the tester to the correct radiator cap interface during pressure checks. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Diagnose

• Cooling system pressure loss
• Faulty or weak coolant cap sealing
• Leaks in the cooling system under test pressure
• Incorrect pressure retention during service checks

Installation Notes and Tips

Use the adapter with the specified Motorad pressure tester equipment and verify the cap interface before testing. The threaded design helps create a secure connection during diagnostics. Confirm the tester setup matches the cooling system service procedure for the vehicle being inspected, including Volkswagen Tiguan, Audi Q5, and Audi TT Quattro applications where this adapter is listed.

Quality Assurance

Motorad manufactures this adapter from high-quality metal materials for professional-grade service use. Part number 3037 is built for repeated cooling system testing in shop environments.
