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.

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.
Review from a similar Frost Plug Style in Vehicle Heaters
Works great, no issues with the product but the cord is short for my Ram since the original connection site is near the back of the engine block. I have to open my hood to plug it in which isn't a hude deal but an extra 8-12" of length would have been nice.
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

It fitted good in the existing plug of the block heater.

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.

good service and price
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
Review from a similar Frost Plug Style in Vehicle Heaters
It was to long to fit in, so it’s in the box nothing I can do with it
Jenny N - 11/19/2021Review 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
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.

Excellent service and excellent condition and place to deal with very happy with product Thanks Bill I just want to know about the other charge on my account if I am receiving another block heater as it was withdrawn from my account if so when can I expect the other one to be sent out
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.
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.

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
I bought this for my John Deere 4320 tractor. I had to take this to my local machinist to move the O-ring to 1/8" away from the plate; the plug opening has only 1/4" of wall available. It now fits and works perfectly!! Much better than the exorbitant price that JD asks for their block heater. I'm perfectly satisfied.
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.

Haven't installed this block heater yet, as it just came yesterday. It looks to be of great quality however, and I have a Kat's block heater in another vehicle that has worked great for years. I anticipate this one will as well.
Richard - 01/25/2019Review from a similar Frost Plug Style in Vehicle Heaters
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!
Paul - 05/31/2019Review from a similar Frost Plug Style in Vehicle Heaters
This product appears well made and durable. Perfect fit with no leaks. Its 400W capacity is less than some freeze plug heaters, but it does warm the engine well. Good price and fast shipping. Overall rating excellent.
