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 Review of the Kat's Heaters Custom Engine Block Heater-KH11486
Hi everybody. Andy here with etrailer.com. And today we're gonna take a look at this Kat's Heaters Custom Engine Block Heater. Now to confirm that this is going to work with your vehicle, take advantage of our vehicle fit guide here at etrailer.com. Input the year, make, and model of your vehicle, and our fit guide will let you know if this will work for you or if we have something comparable that will work for you. This frost-plug heater replaces the frost-plug in your engine block and submerges in the coolant to keep your engine fluids from thickening resulting in a smoother start-up, faster heating into frosting of your cab and less wear and tear on your vehicle in cold weather.
Now, heating your engine coolant is keep, is going to keep it from thickening and freezing resulting in those more reliable startups and smoother operations altogether. But 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 your engine block than starting it when it's cold, your engine will get better initial fuel vaporization, which causes fewer emissions and less pollution. Now, it is important to note that you don't want to use this heater with 100% antifreeze solution nor do you wanna start your engine with this heater plugged in. Now this power cord on the heater is removable.
So just to give you a brief demonstration of that, it can become, you can unplug this from the heater itself, so you're not going to need to buy a whole new heater if the cord gets damaged in some way. The cord can be routed through your grill or easy access to your 120 volt outlet or an extension cord. And if needed, a longer or shorter cord, which is sold separately, can be purchased to better fit your particular application. You do wanna make sure that the heating element is fully submerged in the coolant before plugging it in. This is constructed of corrosion resistant brass.
This is also CSA approved. And the diameter of this heater is 42 millimeters. This has a wattage of 400 watts, an amperage of 3.3 amps. This is made here in the USA. And you are going to receive instructions here that I have folded up here with this heater to help you make sure that you are installing this correctly.
Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

I haven’t installed it yet, however I hope the performance is better than the installation instructions. The newest vehicle listed on the instructions are 9 almost 10 years old. The instructions want you to refer to the vehicle listed but it is nowhere in date.

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

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.

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.

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!!

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.

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.

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

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.

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.

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!

- Difficulty of Installing Kats Heaters # KH11486 Frost Plug Heater in 2009 Jeep WranglerThe Kat's Heaters # KH11486 Frost Plug heater would be compatible with your 2009 Wrangler with the 3.8L V6 engine. It installs into the frost plug location at the rear left of the engine (see diagram). The existing frost plug would be pried off, and the heater would be installed in its place. The Phillips screw on the heater would be snugged down to get a tight fit. Like any modern engine, the space in the engine compartment as at a premium.

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!
