Kats Heaters Vehicle Heaters - KH11405

  • 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: 36 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.

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


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


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

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

Fits perfectly on Nissan NV3500 SL. Had local mechanic do the install so they could properly bleed/burp coolant system after installing unit and refilling coolant. Wrapped cord with semi-rigid cord protector. As good as OEM, which is no longer available from Nissan. Starts heating immediately when plugged in. Be sure to unplug before starting engine.

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.

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.

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 had the Nissan Dealer install the plug and it has worked great since. I put the plug on a timer switch that turns on at 5 am and turns off at 8 am. This has given enough time for the engine block to heat up before we leave in the morning and I hope provide better and faster oil flow to the engine on those cold mornings.

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


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


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


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.

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.

After 1 year, heater is still working great!

Great communication. Great price. The item kh11461 fit my 2004 kioti ck30 perfect. 1/2 hour to install ( including taking off the exhaust ).


Comments
It’s been a year and it is working as advertised. I teamed it up with a smart switch from Kasa that lets me turn it on from an app on my phone and I give it a half hour or so and go out and the tractor starts right up.

Review from a similar Frost Plug Style in Vehicle Heaters


I keep it plugged in whenever the temperature goes below - 15 C. It keeps the engine oil warm, next time starting the car is easy and don't need to warm up before driving, which save time & gas.

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.
