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.

Video Transcript for Feature Breakdown: Kat's Heaters Custom Engine Block Heater

Today we're going to be taking a look at the Kat's Heaters custom engine block heater. This is a frost plug style. It's going to ensure smoother start-ups and faster heating and defrosting of your cab. Simply replaces the frost plug or core plug in the engine block and submerges in coolant. This also is designed to help warm the engine fluid, which is going to increase lubrication and performance. What that does is it keeps the fluid from thickening and protects against damage in colder weather.

It also preheats the engine to reduce condensation in the engine block, so it emits less pollution and fewer gas emissions. It does come with the included removable power cord. That way if you ever damage the power cord, you don't have to buy a whole new element, just replace the power cord. Then you can route this through your grill and plug it into a standard 120-volt AC outlet. The unit's constructed of corrosion resistant brass. It is custom fit for your vehicle. It's CSA approved and it's made in the USA.

When it comes to the wattage that's going to be 400 watts and amperage is 3.3 amps. Installation's simple. You remove the old plug, place this one in, and it's got this really cool kind of device here that as you tighten the screw what it does is it spreads out these arms here, and then that is going to be what tightens it up. It does come with a brand new seal, so it's going to create a real nice seal at the connection point. Then again, the power cord simply just plugs in there. You want to make sure that's pushed all the way down, seated correctly.

Then all you gotta do is plug it in. Couple notes that I need to mention is do not use this heater with 100% antifreeze solution and be sure not to start your 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 frost plug style.

  • Engine Block Heater Install Location for 3.0L Engine in 2007 BMW X3
    Kat's heaters recommends the # KH11431 for the 3.0L engine in the 2007 BMW X3. It's designed to take the place of the frost plug on the right hand (passenger) side of the engine block toward the center of the block. I checked their fit information on their website and wasn't able to find any reference to the # KH30926 being a fit for the 3.0L engine in an X3.
