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.

Video Transcript for Detailed Breakdown of the Kat's Heaters Custom Engine Block Heater

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Kats Heaters 120 Volt 400 Watt Custom Engine Block Heater. Now, this part here will ensure smoother startups and faster heating and defrosting of your cab. This part will replace your frost plug in your engine block, and it submerges in the coolant. This will warm your engine fluid to increase lubrication performance, keeps the fluid from thickening and protects against damaging cold weather.

This will preheat your engine to reduce condensation in the engine block. That'll emit less pollution and fewer gas emissions. Now, it does include this five foot long removable power cord. You'll just route this through the grill, plug it into a standard 120 volt AC outlet, and on the other end, you just line it up with the heater here, plug it in and just like that, you're all ready to go. This will be installed into your engine block, has a gasket on it to help seal it.

Now, this is constructed of a corrosion-resistant brass. It is a custom fit for your vehicle. It is CSA approved and it is made in the USA. Again, this one here is designed to fit 36 millimeter diameter frost plugs on your engine block. The wattage on this is 400 blocks and the amperage is 3.3 amps.

Couple notes on this heater. You do not want to use this heater with a 100% anti-free solution, and you do not wanna start your engine with the heater plugged in. But that should do it for the review on this Kats Heaters 120 Volt 400 Watt Custom Engine Block Heater..

Fit perfectly, no issue since install over a year ago

Great item, works really well and saved me $300 by not going to the dealer, Thank you!



by:

I bought this because it is advertised as a fit for the 2015 Nissan Rogue. When I took it to my Nissan dealership service center, and they attempted to install it, they said it is not the correct size for all 2015 Nissan Rogues because at some point there had an engine block revision that changed the size of the engine block service ports. Thus, the product information on etrailer.com is incorrect, or at the least, misleading. Installation of this item is not an easy task, so to expect the average car owner to disassemble down to the engine block to measure the service port to ensure a correct fit prior to purchase seems extremely unreasonable. When I called to do a return, I was told that because it fits some 2015 Rogues, I could return it, but I would have to pay the return shipping. I got the impression from the person on the phone that she was implying that it is somehow Nissan’s fault, since they revised the engine block. This is also after I had to pay labor for Nissan to attempt to install it without success. When all said and done, I’ll have lost money on this transaction, even if I didn’t have to pay the return shipping. It would just be a slightly smaller hit to the wallet if I didn’t . Poor customer service, etrailer.com. First and last time customer. Buyer beware!



by:

Great service and product.



by:

excellent communication and quality purchase item.
Thanks

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



by:

I needed a frost plug core heater for my tractor. The one I bought did not have my tractor as an application. Just autos and trucks. The measurements were exactly what I needed as well as the wattage. I called a rep to confirm that the measurements were accurate and took a chance and bought it. Exact fit, easy install and happy customer! Thanks Phillip for your help. I highly recommend e-trailer for parts, supplies and great customer service.



by:

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

Great product but took to long to get had to go purchase another one as temps were -35 c so no choice n



by:

Fast delivery, easy check out



by:

Great customer support ! Item received on time .
Thanks



by:

Right part number, wrong or defective threads. Seller refused a refund. I was out of the return policy window, but the product is unused and in original packaging. Defective and unusable. I would expect an exception to be made as this is a major job that has caused my car to be in the shop for weeks longer than it should have been. DO NOT RELY ON THEIR PARTS!!! extremely dissatisfied, I will never be ordering from this company again. Ordered another one from a different company, same part number and it thread right in, after my coolant was drained and water pump removed, sitting in the mechanics shops for WEEKS. cost me lots of time without a vehicle.



by:

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.



by:

Everything came fast. Customer service is amazing. Everything fits and works great. These guys are amazing. Will use them again. Ty Ty Ty



by:

Just what I ordered and great communica tion!



by:

Easy to choose the correct engine block heater for my vehicle on their website. Great follow up throughout the delivery progress. Easy to install instructions, it corresponded well with the OEM detailed instruction. Everything required to complete the installation was included in the kit.

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.



by:

Fit exatlly and the cord was long enouf , and arived on time . I am very happy with every thing and etrailer is very easy to work with . I would recumend their services and products . And Adam E is very good at his job he is truly an assett to your company .

Thank You Dwight

Kat's is the only block heater company that could come up with a perfect fit for my application. I have spent months trying to find a block heater for my rig (on line & in person at parts houses) and nobody else had accurate information - all had the wrong freeze out plug diameters. Success at last!! Thank you Kats!!



by:

It was horrible. Lasted less than 1 week. Heating element burnt out. I got one warrantied and the second one was just as bad. etrailer did do a good job of handling warranty and replaced and refunded as needed. I will continue to shop etrailer, but never buy another product from Kat's



by:

its an Kent 1.6 L ford industrial skidsteer engine common to bobcat,clark,Ghel,Maverick in the late 70's

  • Is Kat's Engine Block Heater for 2008 Chevy Cobalt Difficult to Install
    Since difficulty is mostly subjective, I cut out and added on this page the instructions to the Kat's Heaters Custom Engine Block Heater - Frost Plug Style # KH11405 that fits your 2008 Chevy Cobalt with a 2.0L I4 Engine (it fits the '07 as well). What I can say is that the installation of the heater is not overly involved in regards to the amount of steps needed and is something that people will be able to do if they give it a shot.

  • What Engine Block Heater Fits My 2010 Chevy Aveo5?
    i went ahead and contacted my tech at Five Start Manufacturing (the maker of Kat's Heaters). For your 2010 Chevy Aveo5, they actually made two engine options: 1.6L I.4 and the 1.6L XSE. The only way to use the Kat's Heater's Custom Engine Block Heater # KH11405 is if you have the 1.6L XSE. The way you can tell if you have the XSE engine is if your 8th digit in your VIN is an "E." The location of the plug is in the front left of the engine block. I went ahead and attached a diagram that...
