Zerostart 3100003 Engine Block Immersion Heater for Eagle, Jaguar, Jeep, Renault, Rover, Kubota, Massey, Perkins, Yanmar, 1" NPT Thread Brass Adapter | CSA Approved | 120 Volts | 400 Watts Review:


Like John Deere OEM, but much less expensive. My JD 2025R's Yanmar 3-cylinder diesel works perfectly. When not in use, I leave it plugged in (in the barn) and have it connected to a z-wave outlet that I can turn on from the home. Before I begin getting ready to leave, I turn it on. The tractor has already started effortlessly by the time I get ready and head out to the barn.



Kat's 24150 150 Watt 4"x 5" Universal Hot Pad Heater Review:


Used this as a heat source for my outside dog, who has a bed in an old plastic bread crate in an open-air shed where I park my truck. My first attempt at it melted a hole through the crate, but I learned from it and found a quarter-inch-thick, one-foot-square piece of plate steel. I attached this to the bottom, laid on a piece of wood on the ground, and stacked the crate on top of all that. The steel has It appeared to function well, and I saw the dog in it on several cold mornings. Knowing that he had a place to go if he needed it made me feel better. The dang thing gets hot enough to heat your dog, your engine, your transmission, a tub of water, and with a cast iron skillet you might be able to fry some potatoes. For the money it's well worth it. I plugged it in the other day for this winter, checked it, and no heat. At some point it had burned the wires off where they go into the pad. It may have just gotten too hot with no air circulating under the bed.

The pad heaters perform admirably. After roughly two hours, they start heating up the entire engine compartment. I don't typically leave them on for that long. Since I use synthetic oil, the oil is already warmed up and cannot become too hot. Overall, I'm really happy with the purchase and would heartily suggest the item.

fantastic heater Due to having a four wheel drive and being unable to access it very easily, it had to be properly fitted. The unfortunate perpetrator caught it for a long time. Yes, I did pay for it as well. Though it was worthwhile. starts without any problems at all in 0 degree temperatures.



Zerostart 3100002 Engine Block Heater for Ford, Jaguar, Mazda, Lincoln, Volvo, 3/4" NPT Thread | CSA Approved | 120 Volts | 400 Watts Review:


This heater was put on my 2015 Mazda3 in the fall, and I'm very glad I did. Figuring out where to place this heater seems to be the largest challenge for many. I am unable to comment on how well this fits on Ford pickup trucks or other vehicles, but it is simple to insert into the threaded plug located high up on the back of the engine in my Mazda. The right plug is fairly simple to spot because it is encircled by an orange sealant layer. Simply glance up the back of the engine from below.There are no brackets, exhaust components, etc. to remove. All you need is a ratchet that can reach up there and a 14mm hex bit socket. Installs like this are considerably simpler for me to complete because I have a two-post lift in my shop, but it is also possible to approach the car from below on a creeper while it is up on jack stands in the front.I should have drained some of the coolant from the radiator's bottom to lower the coolant level a little, but instead I simply removed the threaded plug and hurriedly put the heater into the leak. I ended up losing only a couple of glasses of coolant, which I easily replaced. The installation was simple overall, and the cord routing was simple!Because the new cars no longer have a temperature gauge, only red and blue over and under temperature warnings, I use the Torque app and an OBDII bluetooth transmitter to check my engine temperature at various times. Last week, the automobile began at a temperature of 110F right away on a 15F morning and reached its maximum temperature of 180F after roughly 5 miles of flat driving. Absolutely, I would buy and install another one of them.



ABN Silicone Heater Pad Car Battery Heater Pad Engine Block Heater Pad Oil Pan Heater Pad, 4x5 Inch – 120V 250 Watt Review:


My automobile just has this warming pad installed. I'm not yet sure how well it functions.I scrubbed the bottom of my oil pan rather well. I then used a small hand roller to roll the pad into place after adhering it to the oil pan. I sealed the edges with a high temperature gasket to help ensure that it doesn't fall off. I'll test its effectiveness after nightly lows fall below 20 degrees.



Kat's 11409 400 Watt 3/4" NPT Frost Plug Heater Review:


To save money on gas, lessen engine wear during cold starts, and hasten cabin heating, I purchased this block heater.on my 2010 Ford Fusion, installed. Functions like it should. For the frost plug to be removed, a 14mm allen (hex) socket is required.About three hours before I need the car, the block heater is connected into a timer.The use of a block heater can increase total fuel efficiency by up to 10% at -20°C (-4°F). In a test program run by Environment Canada, a car that had reached a temperature of –25 °C (–13 °F) was warmed using a block heater before being put through a simulated urban driving cycle. Compared to cold-starting the car and taking the same route, this led to a 25% decrease in fuel use.
