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.

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.

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.

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.

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!

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 !!!

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:
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.

Do you have a question about this Oil Pan Heater?
  • Will an Engine Oil Heater Help Me Start My Generator in the Cold
    I cannot say for certain but when the temperature that your generator is subjected to is cold, the oil inside the generator is also cold which means it is much thicker than at operating temperature. The thicker oil combined with your low oil shut-off is likely the reason as to why the generator will not fire up in the cold. I have done some additional research online and this seems to be the general consensus as well. The perfect way to combat this issue would indeed be to use the Kat's...

  • Can The Kats Transmission Cooler Be Plugged In For A Long Time?
    Hello Greg, thanks for reaching out. The Kat's Heaters Oil or Transmission Pan Heating Pad # KH24100 is water resistant but technically not water proof. It is intended to be plugged in overnight or for several days at a time. Keeping it plugged in for longer than that is really uncharted territory. This is a trans heater so most people would just plug it in overnight or just for a few hours before you start your vehicle. There is not a specific max temperature listed for this pad since...

  • Recommended Heating Pad for 1 Liter Oil Pan
    The Kat's Heaters Oil or Transmission Pan Heating Pad - 4" x 5" - 120V - 100 Watts # KH24100 is rated for oil pans that are a little larger than what you have. For your application I recommend using the Kat's Heaters Oil/Transmission Pan Heating Pad - 2" x 5" - 120V - 50W # KH26050 instead since it's smaller.

  • Which Kats Heater Do I Use for My 2016 Chevy Equinox 2.4L I-4 Engine
    I checked with Kat's Heaters and they determine which heater to use by the OEM parts that are available for your vehicle. The 2016 Chevy Equinox with the 2.4L I-4 engine did not use a plug heater like the # KH11811, but instead will use an oil pan heater to accomplish the same thing. You will want to use the Kat's Heaters Oil or Transmission Pan Heating Pad # KH24100, which is the correct heater for your vehicle and will work on oil or transmissions with no more than 7 quarts of fluid....

  • Looking for Block Heater for Champion Generator
    Hey Kirk, I would go with a magnetic heater like the Kat's Handi Heater part # KH1190 which you could attach to the side of the block to help keep it a bit warmer. How cold does it get up there? What's the hardest part about living off grid?

  • Can The Kat's Heaters Oil or Transmission Pan Heating Pad Item # KH24100Be Plugged In All Night
    The Kat's Heaters Oil or Transmission Pan Heating Pad Item # KH24100 can be plugged in over night. It is recommended by the manufacturer to only place the pad on a metal surface because it does get hot and will melt plastic. This unit is designed to get hot to keep the fluid from thickening during those freezing temperatures.

  • Is There A Controller For Kats Heaters Oil Or Transmission Pan Heating Pad
    The Kat's Heater Oil or Transmission Pan Heating Pad, Item # KH24100, does not come with a controller. It is more of a basic "plug-and-play" heating pad with no control options. The size of the pan or tank that this heater should be used on is determined by the wattage of the heater.

  • Is There a Temperature the Kat's Heaters Oil or Transmission Pad Gets
    There are variables that will affect the specific temperature output of the Kat's Heaters Oil or Transmission Pan Heating Pad # KH24100, specifically the outside temperature and wind, so there is not a temperature listed. That said, Kat's does warn that this should only be used on metal and to avoid placing the pad on plastic because it is hot enough to potentially melt any plastic surface, which should give you a good idea of how hot this pad can get. Essentially, barring extraordinary...

  • Block Heater Recommendation for a 2003 Dodge Sprinter
    To install the Kat's Heaters Custom Fit Engine Block Heater # KH11814 you will need to locate the cartridge hole on the block, which for a Chrysler it will be on the left or right rear of the block. You will need to clean the hole out and then apply silicone to the hole and the # KD11814 and then insert the heater. No coolant will need to be drained or lost. Once installed in the hole the heater will warm the block and surrounding coolant and oil. For a simpler install you could go with...

  • 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...

  • Does Kat's Heaters Oil or Transmission Heating Pad Need to Attach to Bare Metal
    While it is best to sand the paint off the metal surface, as long as it is clean and free of debris or corrosion, the Kat's Heaters Heating Pad # KH24100 should stick without issue. The pad features 3M tape that will provide a strong attachment point under your oil or transmission pan. The pad itself also has a silicon cover that will resist oil and acid.

  • Does Heating Pad Need to be Placed Directly on What it is Warming
    You can use the Kat's Heaters Oil or Transmission Pan Heating Pad - 4" x 5" # KH24100 and not stick it on the generator but doing that will greatly reduce, if not eliminate, its usefulness. It may slightly warm it up, but there's really no way to know how much heat it will really get; these heating pads are made to stick directly on whatever it is they are heating.
