  • Kats Heaters

Cold weather can make starting your diesel engine harder. This 1,500W threaded immersion heater screws into a 1" NPT opening to warm the coolant before startup, making starts easier, reducing engine wear, and bringing cab heat sooner.


Features:

  • Ensures smoother start-ups and faster heating and defrosting of your cab
    • Threads into a designated opening in the engine block, with the heating element submerged in coolant
  • Warms engine fluid to increase lubrication and performance
    • Keeps fluid from thickening and protects against damage in cold weather
  • Pre-heats engine to reduce condensation in the engine block
    • Emits less pollution and fewer gas emissions
  • Includes removable power cord
    • Route through your grille and plug into standard 240-volt AC outlet
  • Constructed of corrosion-resistant brass
  • Custom fit for your vehicle
  • CSA approved
  • Made in the USA


Specs:

  • Thread size: 1" NPT
  • Wattage: 1,500 watts
  • Amperage: 6.25 amps
  • 1-Year limited warranty


Notes:

  • Do not use this heater with a 100-percent antifreeze solution.
  • Do not start your engine with the heater plugged in.

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 240-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 Detailed Breakdown of the Kat's Heaters Custom Diesel Engine Block Heater

Hi, everybody, Andy here with etrailer.com. Let's take a brief look together at this Kats heaters custom diesel engine block heater. Now, this heater is designed to fit your Caterpillar and Detroit Diesel engines. And on your screen, I am including the types of engines from Caterpillar and from Detroit Diesel that this is going to fit. And this does have a thread size of one-inch NPT. And so, as you probably know, this frost plug heater is going to replace the core plug in your engine block and it submerges in the coolant to keep engine fluids from thickening, resulting in a smoother startup and less wear and tear on your engine in cold weather.

Now, as you probably know, heating your engine coolant is going to keep it from thickening and freezing, resulting in more reliable startups and smoother operation altogether. It's also going to lessen the workload and extend 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 actually get better initial fuel vaporization, which causes fewer emissions and less pollution. Now, I do wanna point out that you wanna be sure that you do not use this heater with 100% anti-free solution, and you wanna be sure not to start your engine when the heater is plugged in. Now, the power cord on this heater is removable.

All you're gonna have to do is loosen this nut and then this plug can be unplugged from the heater itself. So that's nice because you're not gonna have to buy a whole new heater if your cord, for some reason, in some way gets damaged. This cord can be routed through, like your grill, for easy access to a 240-volt outlet or an extension cord. Now, if needed, a longer or shorter cord can be purchased to better fit your application. Of course, those cords are sold separately.

And you do wanna make sure that the heating element is fully submerged in the coolant before plugging this in, or you could damage this heater. This is made here in the USA of a corrosion-resistant brass. This is also CSA-approved. This has a wattage of 1,500 watts and an amperage of 6.25 amps. You will get an instruction sheet to go over a little bit more detail, the specifications and the details of this heater and then to guide you through that installation process.

Well, I think that's gonna wrap up our brief look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.

Didnt even last a year and when you think about how little its used not a great track record, pretty disappointing

by:
I bought this as a supposed upgrade for the stock 750w heater in my 12v Cummins. This heater failed almost immediately, I think I used it twice before realizing it wasn't working anymore. etrailer was helpful and offered to exchange it under warranty, but I did some research and found a lot of negative reviews of this style of Kat's heaters.

I decided I would be better off washing my hands of this heater altogether, and ultimately ended up installing two 750w Cummins heaters in my engine to satisfy my desire to upgrade.
by:
I have used this type of Freeze Plug Heater on different pieces of equipment. With the cold weather is Wisconsin the engine is kept luke warm when this heater is pluged in.

This product was offered at a fair price. Ounce we get the AC unit out of the way it should b a simple to install.
by:
Great price and fast delivery on the Kats block heater I purchased.
Thanks, etrailer folks !
by:
A little slow delivery, good prices, very good products so far. Electrical portion of my order needs more time for durability.
by:
Item is here already and is exactly what we needed for an odd application. We accidentally found the exact unit we needed, delighted to see the vehicle listing in the shipped materials.
by:
Didn’t use it due to lack of instructions. Contacted e-trailer and they quickly put me in contact with the manufacturer.
The answer that the manufacturer had was that the heater may or may not work. The only way to find out would be to start removing freeze plugs and checking.
Kat’s customer service made no offer of instructions or anything else.

by:
Great product. Installed in my Vermeer chipper with an older model Perkins diesel. Works perfectly. Engine starts with ease in NH winters. Way less expensive than local auto parts stores.
by:
Still working as it should. Takes about 2 hours to warm engine enough to start at 10 degrees.
by:
Great product was delivered quickly and on time. When I contacted customer care about verifying my address everyone was polite and professional and very helpful.
