This frost-plug heater replaces the frost plug in your engine block and submerges in the coolant to keep engine fluids from thickening. Results in easier start-ups, faster heating of your cab, and less wear and tear on your vehicle in cold weather.

Notes:
Start your engine easier and warm your cab faster in cold weather with this frost-plug-style engine block heater. Heating your engine coolant keeps it from thickening and freezing, resulting in more reliable start-ups and smoother operation altogether. It also lessens the workload and extends the life of your vehicle's battery. And because starting your engine when it's warm creates less condensation in the engine block than starting it when it's cold, your engine will get better initial fuel vaporization, which causes fewer emissions and less pollution.
This frost-plug heater replaces the core plug in your engine block. The power cord on the heater is removable so that you won't need to buy a whole new heater if the cord gets damaged. The cord can be routed through your grille for easy access to a 120-volt outlet or extension cord. If needed, a longer or shorter cord (sold separately) can be purchased to better fit your application. Make sure the heating element is fully submerged in the coolant before plugging it in.

Today, we're going to be taking a look at the Kat's Heaters Custom Engine Block Heater. This is a frost plug style. This unit ensures smoother start-ups and faster heating and defrosting of your cab. It replaces the frost plug or core plug in the engine block. It's designed to submerge in coolant. It's going to help warm the engine fluid to increase lubrication and performance.
It keeps fluid from thickening and protects against damage in cold weather, and it pre-heats the engine to reduce condensation in the engine block which emits less pollution and fewer gas emissions. It does come with the removable power cord. You can easily wrap this through the grille, and plug it into a standard 120-volt AC outlet. This part right here simply connects to this end of the heater, nice easy connecting. The other neat thing about it coming with a removable power cord is if you ever damage the power cord, you don't have to buy a completely new unit. All you have to do is replace the power cord.
This is constructed of corrosion-resistant brass. It's custom fit for your vehicle. It's CSA approved and it's made in the USA. The diameter right here is 30 millimeters, wattage is 400 watts with an amperage of 3.3 amps. A couple of notes that I need to mention real quick is when you're installing this, just takes a flat blade screwdriver to tighten that. As you tighten that screw, it spreads these arms apart here which is going to help create that nice tight secure fit.
Do not use this heater with 100% anti-freeze solution and please do not start the engine with the heater plugged in. That's going to do it for today's look at the Kat's Heaters Custom Engine Block Heater.

Glad we could help, Chad! Let us know if there is anything else you need! ^___^ Out of curiosity, where are you located? We get orders for these fairly often, but it's always something I want to ask people.

Still working, had purchased the Amazon knockoff the two years prior and each one only lasted a year. Bought the Kats and it’s still working this year.

Hey Russell. Thanks for taking the time to share this feedback. We don't have a way to track these types of applications so I know it will be helpful to someone else along the way!
