Kats Block Heater for Mazda 3 2012 Skyactiv

Question:

Thanks for locating the frost plug for me. Does this part number thread into the frost plug opening? The instructions often refer to one of those fore-aft squeeze butterfly bolt and fastener.... Thanks

The Kat's heater part # KH11409 plugs into one of the freeze plugs in the back of the engine block. There should be a couple different options to use, but use the rear most hole. It is recommended to use a certified mechanic for install. When installing it, you need to drain all of the coolant from your radiator, submerge the heater in coolant before energizing it, then you can install the block heater. You need to use a 50/50 blend of coolant and distilled water. I am going to attach a photo of the instructions to help you with the process.
