Kats Heaters Vehicle Heaters

  • Engine Block Heater
  • Frost Plug Style
  • 400 Watts
  • Kats Heaters
  • CSA Approved

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.


Features:

  • Ensures smoother start-ups and faster heating and defrosting of your cab
    • Replaces frost plug (core plug) in engine block and submerges 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 120-volt AC outlet
  • Constructed of corrosion-resistant brass
  • Custom fit for your vehicle
  • CSA approved
  • Made in the USA


Specs:

  • Diameter: 24 mm
  • Wattage: 400 watts
  • Amperage: 3.3 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 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.

The only concern I had which I had emailed prior to assembly is the round gasket that is supplied is too big and sloppy even though I had used high temp thread sealant the gasket should of had a better fit. I will find out this winter as for heating capabilities. Thank-You!


Comments
Although still a concern of the oversized seal I’ve had no issues of leakage and it has worked well. Good purchase.

Review from a similar Frost Plug Style in Vehicle Heaters


This review is for block heater KH11461 installed in a Mahindra 5010 with the 49 hp Daedong engine, after one year. This block heater came with the tapered bushing to fit in a 1 1/4" frost plug hole next to the starter. Tap out the frost plug (screwdriver, hammer) Tap in bushing (hammer piece of wood and sleeve retainer from NAPA). Screw in the block heater. Fill with antifreeze and run the engine to ensure there is no air in the cooling system to prevent burning out the heater. I also added a battery heater and trickle charger all on 1 cord permanently mounted under the hood. This now starts well below zero easily. etrailer has a video of this product.

The Kat's website says this part number does not fit my 4Runner but your website and the paperwork in the packaging says it does fit. It's leaking around it so they must be correct and your site is incorrect.


Comments
I wanted to reach out to you in regards to your review on the engine block heater. You mentioned that the heater is not working correctly and I have a question that I would like to ask. What size engine does your 2000 Toyota 4 Runner have?
-- Etrailer Expert Jenny N - 12/27/2021
Engine size is 5ZFE, 3.4 L V6
-- comment by: Desiree - 12/27/2021
I have reached out to the manufacturer and confirmed that it will fit a 2000 Toyota 4runner with a 5ZFE, 3.4 L V6 engine. The best location to install the heater block on a conventional front facing engine is the left rear location.

Review from a similar Frost Plug Style in Vehicle Heaters


excellent for farm tractors; use on perkins diesels ,and simpson diesels; just installed and is working fine! a good one should last 20 years; the one I replaced (for a tractor from a tractor supply house lasted less than 2 YEARS, the one before had gone the 20 years) your block heater has a heavy duty cord and the threaded cuff lock down nut on the sender was an all time first for me, thanks. To use this kit 11409 your must already have the block bushing or the bushing for a block heater for this kit will be # 11461b and about $7.00. Noticed your were in SPRINGFIELD TN; I farm in Tn and Ky. good for you. thanks again. TERRY FITZPATRICK, Austin, Ky

Review from a similar Frost Plug Style in Vehicle Heaters


I just received this block heater today and have not installed it yet but it looks real simple. etrailer.com was a great price and fast shipping


Comments
It was simple to install once I figured out how to drain the coolant from my 2016 Ford Edge. Had to remove a few vacuum lines in order to get my arm into the correct angle to thread it into the block. Works great. Far better than the $400 that Ford parts wanted for their kit.

Review from a similar Frost Plug Style in Vehicle Heaters


I am very satisfied. I had looked for awhile for this size and let me tell you, This company communicates and keeps you informed of your purchas and shipping. I installed this in a 1986 Massey Ferguson 3cyl diesel. No one else carries this size that I could find. I will buy from again.

Review from a similar Frost Plug Style in Vehicle Heaters


Heater is good but it didn't fit in the frost plug hole that had the existing heater in. This replacement had a longer element and it touched the inside of block no matter what angle i turned it and would not seal properly. I think if it was in one of the other frost plugs maybe it would work? I have ordered many other block heaters from here with no issues. Like I said prob fits in different frost plug location so beware have a plan b ready. Hard to give bad review at these prices

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.

Review from a similar Frost Plug Style in Vehicle Heaters


Overall the product is very good. Its a 5 BUT........

Easy to install, but You have to be very careful not to over tighten or rake it will leak. (Like I said, my gulag for over tightening it. (but dang, it is a real fine line between loose and over tightened! Lol) Maybe torque specs needed!?!?

Used it to keep boat diesel motor warm all winter in the northeast.

In any case, keeps the Lehman 120 Diesel in my boat toasty warm. (I installed two on a thermostat and it works like a charm. Fire her up in the middle of February to go out for cod.

Review from a similar Frost Plug Style in Vehicle Heaters


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.

Review from a similar Frost Plug Style in Vehicle Heaters


This worked perfectly. It wasn’t made for the tractor I put it on, so I had to fabricate an adapter and then all I had to do was plug it in. About 30 minutes after plugging it in and the engine will start in the coldest weather. Great product and great service from etrailer.

This was a great quality frost plug but unfortunately I bought the wrong one, never ended up using it. Sold the vehicle and bought a different block heater for my new car.

Review from a similar Frost Plug Style in Vehicle Heaters


hi
put this block heater on a Kubota
D1105 (RTV1100) , 2012. In place of a heater that was already there . tighten up screw to specs, I could take one finger and wiggle it. was worried when it got to temp , it would leak or pop out and lose my engine. the old one was a friction fit, not a butterfly hold .
I have got other things from etrailer that were good, blocker heater did not work with this case. Not etrailer fault. KAT heater KH11487 not up to the job, have to go back to Kubota to get part.

Review from a similar Frost Plug Style in Vehicle Heaters


This product works perfectly! It was installed on a 2006 Ford Escape XLT. I had a dealership install the heater. Living in the Midwest, on mornings below 10 degrees, I can definitely tell a difference in the car starting. The heat was slightly warm immediately after starting the car. This heater was used everyday for four months in the middle of winter in ND. The car was parked outside all winter and was plugged in all night. No issues! I would highly recommend this product.

Review from a similar Frost Plug Style in Vehicle Heaters


Ordered 2 of these for the twin 5.9 Cummins engines in our boat. Installed them into a 3/4" NPT fitting in the head of each motor. Work great so far, keeps the motors just under 100 degrees. Makes starting much easier and almost no smoke out of either engine.

  • Does Kat's Custom Fit Engine Block Heater Have A Thermostat Or Does It Stay On When Plugged In
    The Kat's Heaters Custom Fit Engine Block Heater, part # KH11479, is not designed with a thermostat. There would be power to the heater when it is plugged in and it does not have an auto shut-off.

  • Kat's Engine Block Heater for 2006 Hyundai Sonata With 3.3L V6 Engine
    I confirmed with Kat's that the Kat's Heaters Custom Engine Block Heater - Frost Plug Style # KH11479 is a fit for your 2006 Hyundai Sonata with a 3.3L V6 engine. The correct location to install this plug is in the "RC" or right center location as in the accompanying diagram from Kat's. This location should be accessible from the top after removing the cover that is on the engine.

  • Where do I Install the Kats Heater # KH11479 on My 3.3L V6 on My 2015 Hyundai Santa Fe?
    The correct heater that is designed to fit your 2015 Hyundai Santa Fe with a 3.3L V6 is the Kat's Heaters Custom Engine Block Heater - Frost Plug Style # KH11479. For the frost plug location on your engine block, it is located on the right center (RC) of the block. The plug will differ in location depending on if you have a traverse engine or a conventional engine. I went ahead and attached some photos to help you with the process. Once you find the plug, the heater simply inserts into it.

  • Block Heater Plug Location on a 2015 Kia Sorento
    Whether you are installing a heater like part # KH11812 in a 2.4L engine or part # KH11479 in a 3.3L engine the location of the plug will be in relatively the same place. Kat's Heaters denotes the location of the plug to be in the rear right position which is the point of your engine that is closest to the passenger seat in your 2015 Kia Sorento. I am sending you a link to the diagram in a separate email.

  • Where Does the Block Heater Install On a 2015 Kia Sorento
    The correct block heater for a 2015 Kia Sorento is the Kat's Heaters Custom Fit Engine Block Heater part # KH11812 for models with the I4 2.4L engine and part # KH11479 for models with the V6 3.3L engine. In regards to installation, I can only provide a general location to look in. I checked with Kat's and they recommend "2nd RR" for the I4 2.4L engine and "RR" for V6 3.3L engine. I have attached a photo below to help make sense of the above abbreviations.

  • Kat's Heaters Block Heater Location For A 2016 Kia Sorento GXG5
    The specs I'm seeing for a 2016 Kia Sorento GXG5 show it having a 3.3L V6 engine so you would instead want the Kat's Heaters Custom Engine Block Heater - Frost Plug Style - 120V - 400 Watts - 24 mm # KH11479. This is going to install in the "RR" position of your engine. If you do really have a 2.4L 4-Cylinder engine then the Kat's Heaters Custom Fit Engine Block Heater - Cartridge Style - 120V - 400 Watts # KH11812 you purchased is going to install in the "2ndRR" position.
