The Motorad 3006 Tester Hose and Head Kit is a professional-grade adapter built for use with MT-300 cooling system pressure testers, helping shops and DIY mechanics confirm that a vehicle's cooling system is holding the correct pressure. Constructed from a combination of plastic, metal, and rubber components, this black kit features a twist-on attachment style with a 0.25 in thread size and 0.20 in neck diameter, designed specifically to test coolant caps for proper sealing and pressure release. The kit includes both the hose and a gasket/seal, so you have the pieces needed to connect to your existing MT-300 tester setup without hunting for separate parts. Whether you're diagnosing an overheating complaint or verifying a repair, having a dedicated coolant cap tester adapter helps you isolate cap issues from other cooling system problems, giving you a clearer diagnostic path and more confidence in your findings before returning a vehicle to the customer.
