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.

Toyota Tacoma

It's a fairly tight place to get into on a Tacoma to install, but once the heater is installed, the fit is good and snug. The heater works great, I have heat coming through the vents less than 3 blocks from my house.

I would recommend this product to anyone.



by:
Toyota RAV4

Well this item installed on my 2020 Toyota RAV4 did fit but it is not as easy as with earlier models and located on the front left hand side (down low) instead of on the right hand side bank. I used the factory block heater installation instructions as a guide but found some of the steps unnecessarily (for example removing the air box). In any case be prepared to do a lot of it by feel because you cannot see the hole it slides into in the block unless you use a mirror and flashlight. The installation process took me about 2 hours.

My Vehicle: 2021 Toyota Tacoma TRD Off-Road (4.0L 6cyl Auto)

This item is good quality but does not fit properly. It’s as if the circumference is a millimeter or two too-wide to fit in the engine block; it stopped itself maybe 3/4 of the way from a full install.

I bought this item before back in 2021 and had to remove my previous heating element due to it almost “melting” out of its socket because of the same issue I mentioned above; the clip would not secure no matter how hard I tried (“hammering” it in with a breaker bar *I made sure to not damage the electrodes* or even freezing it so the metal would hopefully shrink that extra millimeter or two).

Issue seriously needs to be resolved.

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.

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.

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.

I installed this unit on my 2017 Tacoma when it had less than 10k on the odometer. Even with the engine bay clean and in like new condition, the heater was really difficult to install. The fit was really tight. I could not get it in the whole way and I did not want to tap on it with anything in fear of damaging the unit. With that said, it's in there and pretty much stuck. I have plugged it in during the cold months. When I fire up the truck in the morning getting ready to leave for work, I really can't tell if the Oil or Coolant are any warmer than if I didn't have the heater plugged in. Warm up times are about the same and the truck heater starts to warm up at the same time. I also don't know if it's ok to have the thing plugged in all night or if it should be on a timer. The instructions did not say. So all in all, For me I think it was a waste of money. The only thing it has done is spark up conversation when people see an extension cord plugged into the front of my truck. They say "I didn't know the new Tacoma came in a diesel?" Oh, one more thing. They sure could have made the electrical cord a few feet longer. I like doing a nice job of routing wires in my engine bay. The cord provided is so short you basically need to make a straight shot from your firewall to your grille.



by:
2014 Toyota Tacoma

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.



by:

already installed, took about 20 minutes, only issue is the clip is a little flimsy, had to bend it a bit to get a decent bite. thanks

Installation was surprisingly not dramatic…and everything is working as promised. Thanks once again for also the constant checking with me to make sure I received the product; very appreciated.

2016 Toyota Corolla

The KH11813 block heater has worked great in my 2016 Toyota Corolla! I installed it, along with other winterizing necessities, and found that it was extremely easy and straight forward. The cavity that it fits in is on the driver's side of the motor just above the transmission. My wife was able to put it in place from the top after I removed the air cleaner box. Her small hands made it very easy to place, while I was able to clearly see the notch where the clip hooks from under the car without removing any parts. I've had it in service for about 2 months now and it has kept my block nice and warm in temps down to -30. I would highly recommend this heater to anyone that needs one.



by:

Product still works great! We just had a blast of old man winter with temps in the single digits. This unit does an awesome job as far as helping to keep the engine block warmer, and makes for quicker heat output.

2015 Toyota Camry

This heater i installed myself on a 2015 Camry. Excellent product, as good as oem. There is no heatsink compound nor protective cap for the ac plug however. etrailer rep will be happy to find you one if needed. As for the grease, go for electronic shop or computer shop and buy heatsink compound for cpu. Forget the dielectric grease for automotive, wrong purpose.



by:
2015 Toyota Tacoma

Wouldn't work on my 2015 Tacoma pickup. Toyota attached a bracket next to the hole so that it partially overlapped the hole preventing insertion of the heater despite the website indicating the correct part number. Then I am being charged return shipping cost. Not happy.

Dale, thank you for your review and your business. According to our installation video for the 2016 Toyota Tacoma, which may be found at the following link, temporary removal of the rear skid plate will allow you to snap the heater in place. I hope this helps.



by:
Toyota 4Runner

Although these are marketed as fitting a '08 FJ, a '14 & '15 4Runner & Tundra; They do not. They will not fit in the specified location, they came apart and now they are stuck in the engine block and are useless pieces of junk. DO NOT BUY THIS!! Even my mechanic says these are not worth it. I contacted ETrailer.com and they wouldn't accept a return.



by:
Toyota Venza

Purchased this for my Toyota Venza with the 3.5 2GR-FE engine. Installation was super easy, and this block heater seems to be working just fine. I generally have it set on a timer to warm the engine anywhere from 2 to 4 hours (depending on outside temperatures), and so far, it has worked as it should. For the tiny amount of money this costs for electricity while in use, I'm sure the fuel savings with faster warm up time will make up for that.....

  • Troubleshooting Block Heater that Is Difficult to Install in 2015 Toyota Tacoma
    As long as you have found the correct hole in your 2015 Toyota Tacoma the Kat's heater part # KH11813 would be correct for it and should slide right in. Since the hole is somewhat difficult to access you are most likely not angling it in correctly. Make sure you are trying to install it in the correct hole (see pic) and that it is lined up perfectly square as you insert it. We have heard that the catalytic converter bracket on the 2015 model can be somewhat in the way too.

  • Should Block Heater be Unplugged Before Starting Vehicle
    You'll want to unplug the block heater before you start the engine for a couple reasons. Mainly so that you don't accidentally drive off with it plugged in, but also so that the extension cord would possibly get wrapped up in moving parts or hot components. Having the block heater on while the engine is running won't necessarily cause any adverse effects though. If you feel near the block when it's on you'll feel it warm.
