Maradyne MFA135 Details

The Maradyne MFA135 heater water valve temperature control kit provides precise control over heater output by regulating coolant flow through the heater core. Designed for ease of use and a clean, factory-style appearance, the kit features a molded plastic rotary knob and bezel for professional installations. Temperature adjustment is achieved through water flow control—clockwise rotation fully opens the valve for maximum BTU output, while counterclockwise rotation gradually reduces flow to completely shut off heat. The durable valve includes 5/8" hose barb inlet and outlet connections for secure installation in most heater systems. Complete with valve, rotary knob, and bezel, this kit is an ideal solution for controlling cabin heat in a wide range of automotive applications.

This worked perfect for flow control on the Inferno heater I put on my 2018 Yamaha Wolverine RSPEC EPS. It has a true off/closed position for when you don't want flow through the heater core, which is what I was wanting for the hot days when you need max cooling from your radiator. I didn't have any issue installing it, or with the bracket. You may have to remove the bracket and turn it upside down from your intended orientation, if you want to use the bracket as a template for the 3 holes you will need to drill.
