Features to know about
Get Thick Oil Moving Before a Cold Start
When temperatures drop, thick engine oil creates more resistance during cranking and takes longer to circulate. This 125-watt silicone pad warms 3 to 6 quarts of oil through the metal pan, making those cold starts easier on your engine. It can also warm 1 to 7 gallons of hydraulic or transmission fluid, useful for equipment that sits outside or in an unheated shop during winter.
Fit a Round Pad Where Space Is Limited
Not every oil pan or transmission housing has room for a long, rectangular heater. This 3" round pad gives you another mounting shape with which to work. You'll need a flat, smooth metal area at least 3" in diameter, with enough clearance around it to install the pad and route its cord. It attaches to either steel or aluminum, so you're not limited to magnetic surfaces.
Note: The round shape doesn't mean the pad can wrap around a curved pan. The entire heating surface must contact flat metal without gaps, ridges, or grooves.
Regulate the Heat While Your Equipment Is Parked
The built-in thermostat cycles within a 170F to 200F range to regulate the pad's temperature. Actual fluid temperature depends on the weather, fluid volume, and installation. Once the heater is properly mounted, the included 6' grounded cord connects to a standard 120V outlet when you need to warm the fluid.
Combine Oil Heat With Other Winter Starting Aids
An oil-pan heater warms the lubricant, while an engine block heater (sold separately) primarily warms the coolant. If you're dealing with severe cold, using both addresses different parts of the starting process. A battery heater (sold separately) can also maintain available cold-cranking amps, giving you another way to prepare a vehicle or piece of equipment for winter starts.
Cold-Weather Experience Behind the Zerostart Name
Zerostart is a Phillips & Temro brand, from the company behind a broad line of engine, battery, and equipment heaters. If the Zerostart name is new to you, this pad comes from a manufacturer that has spent years developing products for cold-weather equipment operation.
Important Notes:
1. Choose a Flat Metal Surface:Install only on steel or aluminum with enough flat, smooth space for the entire 3" round pad. Avoid ridges, grooves, raised areas, and curved surfaces. Do not install on plastic or composite materials.
2. Prepare the Surface:
Remove paint from an area slightly larger than the pad and scuff the metal with sandpaper. Clean with acetone or brake cleaner and dry completely. Warm the mounting surface above 100F (38C) before applying the pad.
3. Apply and Seal Properly:
Remove the adhesive backing and use the included scraper to press the pad firmly against the metal, removing air gaps. Apply the included silicone sealant around the edges, not underneath the pad. Do not use additional adhesive to secure it. Wait 24 hours before regular operation.
4. Protect the Heater and Cord:
Never cut, trim, or puncture the pad. Keep the cord away from excessive heat, moving components, and abrasion. Use a properly rated grounded extension cord suitable for outdoor use when needed.

I tested out the Zerostart Silicone Pad Heater, and I like how simple but effective it is. I was really impressed that it has a built-in thermostat that keeps the pad from overheating and protects the fluid it’s warming. It also saves energy by cycling on and off as needed, which means you can leave it plugged in without worrying. I also like that this one has a round design, it fits really well on curved or rounded surfaces like oil pans or transmission housings, and it gives more even heat across the surface. The silicone material feels tough and made to last, even in harsh conditions. Overall, it’s a well-designed heater that’s tested to fit and built to perform when the temps drop.

See what our Experts say about this Zerostart Oil Pan Heater
- Will A 125W Heat Pad Be Enough For 6 Quart Oil Pan On Pickup In The Winter?Roger, the Zerostart 3 inch pad # ZE75MR is rated for 3–6 quarts, so you’re right at its upper edge. It’ll still help, but if you’re in extreme cold below –10°F or want faster heat-up, adding a second pad would perform better. Either way, you'll be safe to use it overnight as it has a thermostat that shuts it off or turns it back on when needed. We also have a magnetic version # ZE35MR which puts out a little more heat and it just sticks onto the steel surface, then removes when you hit...
view full answer... - What Is The Difference Between Zerostart Heat Magnet And Silicone Heat Pad?Good question, Luis. The Heat Magnet # ZE35MR runs hotter - up to about 250°F on its metal contact surface - while the Silicone Pad # ZE75MR cycles between 170°F and 200°F. The magnet’s higher heat is ideal for thick oil or frozen hardware, and the pad’s gentler, adhesive-based warmth suits long-term fluid warming on sealed pans. The main difference comes down to how the magnetic version is not permanent and needs to be removed before the machinery/vehicle drives off, while the silicone...
view full answer... - Can Magnetic Heater Pad From Zerostart Be Used On Aluminum Surfaces On Equipment?Ken, for aluminum, go with the adhesive Zerostart pad # ZE75MR instead. It’ll bond directly and heat evenly across the surface. The # ZE35MR magnet heater only transfers heat effectively through ferrous metal, so aluminum won’t work - even if you clamp it, most of the heat will stay in the heater itself. What equipment are you heating?
view full answer... - Will Stick On Heater Pad Work To Keep Big Hydraulic Pump And Reservoir Flowing Good In Unheated ShopDefinitely, Walt. Cold oil thickens and bogs hydraulic systems and pumps down when you first start using them. If the tank or crankcase is steel, the Heat Magnet # ZE35MR works great and is easy to move when hitting the road. If it’s aluminum, use the Silicone Pad # ZE75MR - it’ll stick permanently and keep the oil warm enough for smooth startups. How big is your system? What exactly are you using it on?
view full answer... - Magnetic Heat Pad To Stick On Polaris Ranger UTV Engine And Transmission To Heat Up Fluid And OilJake, absolutely - the Zerostart # ZE35MR magnetic heater is a great match for small UTV engines if the oil pan is steel. It delivers 200 watts of localized heat, which thins the oil and eases cranking even in sub-zero temps. Also helps warm the engine up much faster! If your pan’s aluminum, swap to the silicone pad # ZE75MR instead. How long are your cold starts taking right now? And does your battery ever go weak? That’ll tell us if pre-heating oil alone is enough or if a battery warmer...
view full answer... - Can Zerstart Silicone Heater Pad Flexible Enough To Mount On Curved Transmission Pan?Alan, the Zerostart Silicone Pad Heater # ZE75MR has a small amount of flex for slightly curved or uneven metal surfaces, but it’s not meant to wrap around corners or big bends. The heating element needs full, even contact to transfer heat properly. Make sure the metal is clean and dry, warm it up a bit (around 100°F) before applying, and press it firmly in place for a solid bond. Are you planning to use it on a vehicle or on stationary equipment? That’ll help narrow down the best mounting...
view full answer... - Can ZeroStart Transmission And Oil Pan Heaters Stay Plugged In Overnight?Yep, you're fine, Mary. Both the Zerostart Heat Magnet # ZE35MR and the Silicone Pad # ZE75MR have thermostats that cycle off around their rated temps, so they can safely stay plugged in overnight. Many users keep them on all night to ensure an easy morning start. Just be sure cords are clear of hot or moving parts, and unplug them when you're ready to start and hit the road. What vehicle(s) do you plan to use these on?
view full answer... - Log Splitter Hydraulic Fluid And Pump Is Too Cold During Winter Months - Heater PadYes, Pat, the Zerostart Silicone Pad Heater # ZE75MR is designed for exactly that type of setup. It’s rated for 1–7 gallons of hydraulic or transmission fluid, and the 125-watt output with a 170–200°F thermostat will keep your hydraulic oil moving smoothly on cold mornings. Just make sure the tank surface is bare, clean metal before sticking it down. How big is your tank? I can help confirm if one pad is enough or if doubling up makes sense.
view full answer... - Can Zerostart Silicone Pad Heater Be Installed Outdoors Or Does It Need To Stay Dry?Randy, the Zerostart Silicone Pad Heater # ZE75MR is fully sealed in silicone, so it’s weather-resistant and safe for outdoor use. Just keep the plug connection out of standing water and route the cord securely. It’s a great choice for exposed farm or construction gear, such as hydraulic systems, oil pans, engine blocks, transmissions, etc. What do you plan to use it on, Randy?
view full answer... - How To Keep Engine Oil Viscosity High During Winter On Big Generator - Oil Heat PadGood question, Terry. If your generator’s oil pan or engine block is steel, the magnetic Zerostart # ZE35MR is easier - it sticks instantly and can be moved to other equipment. But if the part is aluminum, the magnet won’t grab, and the Zerostart pad # ZE75MR would be the right pick. It adheres permanently and provides steady, moisture-sealed heat. Both draw minimal power and make cold starts way easier. Do you run that generator on a timer or plug it in manually before storms?
view full answer... - How To Pre-Heat Electric Steps On RV Motorhome In Alaskan Winter So It Doesn't Jam In Snow And IceHey Shelly! Interesting idea there. It's not technically designed for that specific situation, but I don't see any reason why you couldn't do that! The Zerostart Heat Magnet # ZE35MR works great for that kind of cold-weather fix. Just attach it to a flat steel part of the step frame or mounting bracket (anywhere on the bottom of the step away from the motor and wiring), and it’ll transfer steady 200-watt heat through the metal to melt ice and free up the moving parts. It’s a quick way...
