Video Transcript for Ultimate Overview of the Kat's Heaters Oil or Transmission Pan Heating Pad

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Kat's heaters, 120 volt/250 watt oil or transmission pan heating pad. Now basically, you can place this heating pad under your oil or transmission pan in your vehicle to keep the fluid from thickening in the winter. This measures about five inches long, four inches wide and as you can see, has a cord on it, that allows you to plug into a 120 volt AC outlet. Now basically, warm fluids will lubricate better for a long-lasting well functioned machine. The warm transmission fluid allows for smoother gear shifting and the warm oil provides better lubrication for longer lasting, better functioning engine.

Also, you can use this to heat hydraulic and water tanks if you prefer. This does resist oil and acid, has a nice silicone cover to it, on the underside, if you notice, you can attach it to the underside of the vehicle's oil, or transmission pan with the 3M tape. Just clean the surface very clean, pull that off and it'll stick right on there. Again, you just plug this into 120 volt outlet. The cord, if you extend it all the way out, is about five foot in length and as we mentioned, provides 250 watts of heat.

This part is made in the USA. Now, a couple possible applications for this. This will work, this size pad will work for eight to 20 quart engine oil pans, 10 to 20 gallon diesel tanks, 10 to 20 gallon hydraulic tanks and four to seven gallon water tanks. And again, just to show you that the dimension we're talking about, there's your four inch width and there's your five inch length. But that should do it for the review on this Kat's heaters 120 volt, 250 watt oil or transmission pan heating pad.

We use it on the oil pan of our sprinter fleet. We run in subzero temps a couple times a year and this works great for us when our fleet has to sit outside overnight. Great product just make sure to research the size you need for your application.

It should be, Robert. This isn't a super complicated install or anything like that. Stick it on and you are good to go! Where are you located? Always curious about that when people buy these kinds of things.

@Robert Haha! Definitely need to keep your parts warm! : ) I'm actually from California originally (specifically Lake Elsinore and then San Diego) and we used to take a yearly summer trip up to Mammoth for mountain biking. I think we went up to Bridgeport a few times after checking out Mono Lake. If it's where I'm thinking, it was very pretty! I sometimes forget how much I miss the mountains being out here in Missouri now. Just about as flat as you can get. Everything is quite a bit less expensive out here though, so there's that I guess.

Made in USA!

Easy installation and heats up quickly.
by:
Installation was a snap as my generator was still hot from running. Peeled off the liner to expose the adhesive and stuck it squarely and securely on the underside of the oil pan. My review is only 4 stars because I haven't yet put the product to the test, but when that happens I will revisit and revise my review. Otherwise the heater arrived quickly and was as described.

The blockoil pan heater is used sporadically to heat the oil in our house generator when necessary. We are satisfied with the function of both products thus far. Thanks for reaching out.

I own and operate a tree service in MI, needless to say the winter months are hard on our equipment. I had searched for quit some time before I found this product, it was a very easy installation and makes a world of difference, I would highly recommend this to anyone who works in the cold weather. Thank you Kats !!!

Great Product! Volkswagen Jetta TDI makes no electrical heaters. There is NO frost plug on the engine either! Installed the KAT and life is good! Starts every time.

The pan heater is going strong. The 2003 VW TDI does not offer any solutions to warming up the engine so I chose to do the pan heater over cutting into the cooling system. I would do it again!

by:
I put this heater on my RV water heater to prevent it from freezing. So far it works well.

This item works great. I dont have to drain my RV water heater in the winter. Just apply it to the tank and it prevents freezing.

by:
I bought this pad heater for my air compressor that lives in the unheated side of my shop. I ruined two electric motors due to the oil in the compressor turning to molasses during the winter where it gets well below zero. So far so good. :)
The adhesive is solid, not peeling and the pad keeps my compressor nice and toasty. Before when I was away traveling I would forget to open the breaker for the compressor and come home to a ruined motor. That problem is history.
I highly recomend this heater, very small but very effective for oil pans of all types needing to be kept warm in freezing condition.
by:
So far so good. Bought 3 for our diesels. Be sure to clean the oil pan for any dust, grime or grease. We even lightly sanded the oil pan to ensure good adhesion then used high temp RTV silicone around the edges.

Absolutely zero problems. Continues to work great!!

by:
Was disappointed. Their product description along with the installation instructions both refer to "self adhesive" but there is none. Called manufacture and they suggested High temp silicone RTV. Do to the location of installation this was difficult to do the clamping. Added 4 days for 2 people to the process to install.
by:
Used it to keep oil warm on my GENERAC generator for easier starting during winter months but the electrical connections on the heater were so poor that they were arcing and sparking like July 4th fireworks!! So I ripped it off, too unsafe.
by:
Just received heater today.
Looks like it should be perfect for the oil pan installation on my Kubota diesel UTV.
Hope to do a after season review next spring.

Working great. Diesel started every time!

by:
Works awesome! This is the second one, the first burned out after two years. We use them on 4 wheelers in the winter, on timers for 2 hrs twice a day. Put on lower crank case to warm oil...starts much easier. This one still working well after 1 year.

Still working fine

by:
I installed this on a DEF tank in my diesel to keep it from freezing when I’m parked overnight in sub zero temps. I ran the cord along the frame rail as far as it would reach then attached an extension cord and routed that to come out in the same area as my block heater plug. Be sure to clean the surface of whatever you’re attaching the pad to in order to get good adhesion.
by:
This is the second Kats engine heater I have purchased and both are good quality and durable. This is also the second purchase I have made at eTrailer.com and I am totally satisfied with the cost, the no charge shipping, fast delivery and great follow up to make sure my order was correct and was delivered. I will definitely order from eTraler.com again should I need a component or a part.
by:
Installed this heater on the transmission of my Ford Escape. Works perfectly. Now the truck will shift into gear in cold weather. (I know I need a new transmission but the truck is not worth it) but this heater has bought me an extra year out of my truck. Thanks etrailer.
by:
Using heaters to warm up batteries on an electric drag racing car for cool weather racing. Batteries make more power when warm. The heaters work great!
by:
Used on transmission oil pan, works well. Good price, prompt shipping, good advice from tech dept. about placement and installation. Overall rating excellent.
by:
I used this through a winter in the north where it regularly is at subzero temperatures. Truck always started without any issues. I also had heat pads on the oil pan and transmission that I bought from etrailer. At -40+ degrees the truck always started relatively easy.
by:
We use these pads for cold-weather kits on generators. Good product, order early there is a lead time.
by:
This worked great with a hydrolc tank holding 7 gal of fluid. Gets the temp upto 70 deg F in the winter.
Wish it had aa adjustable thermostat.

  • Is Smoke the From the Kats Heaters Vehicle Heaters # KH24250 On First Use Normal
    If it only smoked the first time you used the Kats Heaters Vehicle Heaters # KH24250 then you should be fine. If it continues to smoke after every time you plug it in that then something is wrong and I would recommend you remove it as it is malfunctioning. Most likely the heater had dust on it from packaging and now that it's been used once it won't smoke again.

  • Recommended Pad Type Heater for 1-Gallon Water Tank
    Since you have an unusual application with only 1 gallon of water to protect from freezing I suggest you consider options other than the immersion heater # KH30904. Also note that this item is not rated for use with drinking water supplies. Kat's Heaters also offer heaters in a pad type, such as # KH24500 (500 watts), # KH24250 (250 watts) and # KH24100 (100 watts). These are installed with the included 3M adhesive pad. The 100 watt model # KH24100 is ideal for water tanks up to 2-gallon...
