ABN Silicone Heating Pad 120V - 4 x 5 Inch Universal Engine Heater Car Oil Pan Heater Pad, 150W Electric Heater Pad

I mounted this on my car engine's oil pan. I did what others suggested and sealed the edges with high temp silicone. So far it has worked great for one winter. It only got down to 0° F this winter, but we had no problem. The car started easy and warmed up much faster than it would without this heater attached. It was kind of a bitch running the wire up to where I could connect it to a power cord, but that's to be expected with a front wheel drive vehicle with everything crammed into the engine compartment.

Purchased this product to heat the oil pan in a generator installed in a steel cabinet outside my house here in the northeast, where temperatures are often in the teens and sometimes lower. It throws off a lot of heat! I want this product to last numerous seasons, so it is still too early to comment on that. The adhesive on one side of the pad didn’t adhere well to the metal bracket I placed it on, so I augmented it with epoxy glue and also some metal bars and galvanized wire to ensure that it didn’t fall off. Again, time will tell, but the product looks like it will be very effective. I also wrapped electrical tape around where the wires join the pad, to prevent the heat from melting the insulation around the wires, which happened with a previous, much thinner pad.

not magnetic mount. 3m adhesive. i just hold in place with a cow magnet. gets hot!

These were relatively inexpensive and I picked them up to use on larger metal items in the shop to discourage condensation (seems to be working very well so far). I've metered them and they actually draw the advertized 25w (wasn't sure they would be properly-made given the affordable price) and the backing pad sticks extremely well to a clean surface. I'll be picking up more of these for use in various places. They're very handy especially when paired with a thermostat or PID controller.

So, I jacked my vehicle up in preparation for installation. It was already in the below 0 temps. I pre-routed the wiring and proceeded to remove the liner for the adhesive backing...it didn't stick. I couldn't tell if the cold made the adhesive negligible (you couldn't feel any tackiness) or if it wasn't there at all. I proceeded to apply some high temp silicone gasket to the pad (as I'd heard you'd need this to reinforce anyway). The silicone gasket worked in attaching the pad to the oil pan. I plugged in the heating pad to a working outlet and noticed it heating well. The end of the next day driving home I had already noticed a crack in the cord as well as a crack in the stress relief area. So not only is the cord not polarized, it's not weather resistant or stress resistant. A little disappointed as I put a lot of work installing this pad that had a issues out of the gate and during usage. I expect I might get another day or 2 before the prong end snaps off completely and I have to scrape off the heating pad.

Added this to my son’s vehicle last fall prior to him going to play hockey in Saskatchewan CA. He used it all winter no problem starting it. Easy to install

The pad gets very hot. Nothing on the pad says what the wattage is for this one. Also, the cord seems very cheap and low quality rubber insulation. Gets hot near the pad. I am concerned the cord could deteriorate and melt.

Adhesion was good. I used two small powerful magnets to ensure it stays over a long period of hot and cold cycles through a normal season. Its early in the cold season in Utah here, so I will update as its used. But yesterday was around 30 f so i will be using soon. So far turned it on was very hot quickly. I went w the 1 inch by 5 long and its pretty slim, I may have gotten a bit larger as i could afford the area on oil pan. My bottom pf undercarriage is covered so I think that may help keep it from weathering like some reviews show.
