Kats Heaters Vehicle Heaters - KH11412

  • 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: 30 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.

Glad the heating is working out and keeping your engine warm in the winter. I'll let Adam know that you got everything and make sure he gets that shout out!

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.

2015 Nissan Rogue
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!

If you own a Nissan Titan and live in sub-zero weather, this is the block heater you need. Shipped very fast from etrailer.com, and the price was great!
by:
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.
by:
Great product and has worked flawlessly.
Customer is happy and shop owner is happy.
Good job E-trailer.

Just what we needed! Fast and efficient! We will certainly be using etrailer.com again!
by:
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.

Did not fit for my 2018 Rogue - apparently some of those motors do not allow for a plug

This item was backordered everywhere. Kurt totally helped me out. I had limited time to get this and install it before my daughter went back to Montana. I really appreciate the help and the fact that etrailer had this in stock. Excellent service!!!!

Hey Russell. Thanks for taking the time to share this feedback. We don't have a way to track these types of applications so I know it will be helpful to someone else along the way!

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

Made in USA! The construction quality looks good. Way less expensive than the Subaru brand heater.
by:
Product arrived a day late. Actually, according to the only tracking that is offered by etailer reported it arrived on the date as expected only the product was not left on the porch as reported. I reported this to etrailer and phoned the local post office. The shipping number I had to get from etrailer. Post office said no such number is in the system. The package arrived the next day, with the number that was not in existence. Etailer had started the refund to my card. I had to call them back to again pay for the block heater. Seems the post office is suspect. I think a bit better transparency for the client to track the products would be an improvement.

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!!

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.

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.
