Benefits of a Heated Engine

Start your engine easier and warm your cab faster in cold weather with this cartridge-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.


Cartridge-Style Heater

This cartridge-style heater simply clips into the cavity of your engine block. There is no need to remove the core frost plug. 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. Make sure the heating element is fully submerged in the coolant before plugging it in.

This is the second Kat's heater in this car. The first lasted 5 years or so and worked well so decided to replace with same.


Comments
The second heater only lasted for 11 12 months and failed at the wire to heater connection. I returned it and a replacement has been sent under warranty.

Install was a little tricky given the location for my vehicle 2012 F150. But other than that pretty straight forward. Packaging was good and product seems well put together. Only time will tell if it works well. I'm not in the cold climate yet. It also does come with the 3 prong as advertised.


Comments
Product has held up very well in the frigid North Dakota winters! Very happy with purchase!

Thanks for reaching out. I had just recently sold that truck about a month ago. But wanted to let you know that it has held up very well up here in ND. I had a question. I have recently upgraded my vehicle to a 19 F350 6.7. I wanted to know if you have anything available and if I could get one sent out. For whatever reason, my truck didn’t come with a factory block heater and now with the Ford recall on them. They aren’t in stock anymore and are WAY more expensive then what you guys have. Please let me know, look forward to response

We do not carry a block heater designed to work on a 2019 Ford F-350 6.7 at this time.

Product is fine but, the installation instructions are terrible. Even contacting the manufacturer for the mounting instructions, terrible. Found the mounting place on YouTube. What's up with this?

Block heater gets hot when plugged in not installed. It will burn your hand. The battery wrap does heat up nicely. I have not installed them but assume they will work just fine.

Review from a similar Cartridge Style in Vehicle Heaters


I cannot rate the product (which may be really fine) since there is no instructions given on installation so I'm stalled. Well the so called "instructions sheet" says to put the heater in the "cartridge" but doesn't give the slighlest idea where it is other than stating that for my car its situation is " LF" whatever that means. Not on par with etrailer's business practices !


Comments
I recommend watching the engine block review video that I have linked below. The 2017 Mitsubishi Outlander has a transverse engine which would be mounted perpendicularly to the direction of travel, lying horizontally within the engine bay. You can see a diagram that shows the locations of the holes on the engine in the link below. The LF stands for left front.

2014 Dodge Ram 5.7L uses Kat’s 11816 cartridge heater. Perfect fit. Must remove the two starter bolts and slide it out of the way. Don’t disconnect starter wires. Just slide starter out of the way. Easily done with truck on ramps. Clean out hole. Find a correct size retaining screw. Not sure what size or If hole is threaded. Too much rust. Just be able to jam some screw in there to retain the cartridge, until silicone dries. Smear about an inch wide layer of high temp silicone around the base of the cartridge. Insert cartridge, twist back and forth to spread silicone, and hold in place with retaining screw. Route wire straight forward. I used 1 1/8” spade bit to drill a hole in black plastic in bumper, but my bumper was already messed up, so I didn’t care much. Plug hangs out grill about 3”. Use zip ties to secure cord to square tubing frame post inside bumper.

Installed this on my 2019 Toyota Tacoma. Haven’t really tested it out yet as I installed it before it got seriously cold. Installation was easy. Just follow etrailers super helpful video. I did have to file a slight flat on the heater to clear the bell housing overhang. Not a manufacturer issue on the heaters part. Just normal variance on Toyota’s end.

Review from a similar Cartridge Style in Vehicle Heaters


Does your company do any type of quality control before you send these out? I was wondering what everyone was talking about in the reviews when they said they had to file these down to get it to fit. Indeed I did have to significantly grind/file the circumference of the plug to get it to fit. Now I’m not confident that it’ll stay in the block because I had to modify it so much; something that should have been made right from the factory, who does this for a living. (3rd Gen Tacoma)

I will have our customer service team reach out to you. I did some research and if you have a 2021 Tacoma with a 2.7L I4 Engine then part # KH11481

Review from a similar Cartridge Style in Vehicle Heaters


The heater was easy to install, there was a indent on the engine block that the heater fit in and was held by a clip, routing the cord to the lower grill and holding away from moving parts with the tie wraps took some care as the cord was just long enough. My GMC Acadia spent the winter parked outside in Wyoming so the heater was good on those cold nights especially when I had to leave for work at 5 am, The apartment complex has plugs at every parking space so was very convenient, on very cold nights left it plugged in all night, not sure if it was designed for that but had no problems. Looking forward to another winter.

Very well made, easy to install on Hyundai Elantra GLS 2016 with 1.8 engine. Lightning fast shipping at an incredible price of $[x] from USA to Canada. Very pleased doing business with Etrailer and will do again for sure!

Easy installation once we found the hole in the engine block where it goes, that is the hard part. Worked fine last winter, have not needed it this year.

I bought this a year ago and installed it myself. It was a fairly simple and quick install. The heater works great and I recommend it for the Tundra.

Review from a similar Cartridge Style in Vehicle Heaters


I live in northern Ontario, Canada. Average temp is -20 but has gone as low as -30/-35. This heater was installed in a 2016 Hyundai Elantra GLS 2.0 engine. Installation was easy once the battery box was removed. Slipped in the cavity real nice. The heater was plugged in for 4 hours at -20c. I then tested the engine for warmth. To my surprise the engine block was warm to the touch and the snow had a small circle on the hood where it started to melt. This surpassed my expectation, and I highly recommend this heater. Uses 350 watts per hr. That's less than a frost plug heater at 550 watts per hr. Shipping, packaging and instructions all great.


Comments
This heater is by far the best thing since sliced bread. This little heater will keep the engine warm to the touch at any temp outside. Still working great after one year.

2015 Hyundai Sonata 2.4 install. Have to remove air intake, very tight to get it in just enough space. Had to trim a little bit to make it fit but nothing ever fits perfect. Picture say it all.

I bought the car in Winnipeg MB with NO block heater when I got it home!! Luckily Etrailer had the heater I needed. Installation was a breeze and it works like a champ.


Comments
Unfortunately the car got wrote off last winter so I cant comment on that one but I have had a Kats heater in my other Camry that I installed 8 years ago and it is still working just fine for our Manitoba winters.

Review from a similar Cartridge Style in Vehicle Heaters


The install was pretty straight forward except you have to grind one side of the element at the base flat in order for it to plug in, this is not in the directions. At the base where it bulges out, it gets in the way. Also the cord could be another 2 feet longer, when you route it away from hot exhaust and moving parts it uses a lot of cord. It helps tremendously in -35C, aside from those two points im happy.

Shipping was very fast (2 days) from Florida to Boise.. I have not installed the block heater yet. I'm driving home to Alaska soon and I'll have my mechanic install it there. Required in Alaska for even for gas engines


Comments
The block heater was for my daughters Honda Odyssey that she was moving to Alaska. My mechanic in Fairbanks installed it for me. We had several -40 degree weeks this past winter and her Honda started without fail throughout the long Fairbanks winter. Her Odyssey is parked in an unheated carport.

I purchased 2 block heaters, 1 for my daughters Honda and one for my Chevrolet Colorado. Both were easy to install. This past winter in Fairbanks, Alaska, we had several weeks of -40 degree days and both vehicles had no trouble starting mornings.

Review from a similar Cartridge Style in Vehicle Heaters


Attempted to install into a 2014 Tacoma. After removing the bracket the blocks the hole for the heater, the cartridge would not go in all the way. I discovered that the thickness of the cartridge where the plug connects to makes contact with the engine below the hole. I had to sand a flat part onto the heater in order for it to slide in flush. The clip barely holds the heater in to the point where I couldn't trust it. I attempted to make the bend further down the clip so it could securely hold the heater in but the clip was fragile and snapped. Attempts to contact Kats/Five Star Manufacturing was a waste of time, they never respond. I resorted to making my own clip with stronger metal and a bend at the proper length and it can be trusted to hold now. Do not purchase Kats/Five Star Manufacturing products with the expectation that they have your back if the product is faulty in some way. Purchase OEM block heaters, yeah they may cost a little more ($18 in this case) but you can expect the product to perform as expected.

80% perfect fit! The only thing missing is 90 degree angle for the power cord at the heater(like GM original) also the power cord is not long enough for 2017 Canyon! Otherwise excellent for the price!

It does the job perfectly!
