Oil Pan Heater

This is mostly due to increased oil viscosity and lower battery capacity. Before starting the engine at low temperatures, it is recommended in the car’s owner’s manual to turn on the high beam for a while, the current flowing through the battery will warm it up and restore some of its capacity.


  • High efficiency
  • Ease of use
  • Easy installation

When using any method of heating the engine, it is important to follow safety precautions. The fact is that the design of the car does not initially require a system of oil preheating in the crankcase (unless this is not provided by the specifications). Therefore, it is necessary to consider the requirements of elementary safety. The main of them is to constantly monitor the process. Even if the technical documentation for the heating element indicates an automatic operation of the unit, this should not be the basis for uncontrolled application of the heating system.

Among the most popular heaters are Wolverine, Cummins and Zerostart ones.

Do magnetic oil pan heaters work?

They work very well if you use one of them with a block heater. All it does is it increases the ability of the oil to flow, reducing dry start-up. This will not help with your start problems when your engine is cold, because it does not increase the temperatures where the ignition occurs. The reason block heaters work best is because they heat your water jacket. This keeps the entire engine a little warmer on cold nights. It increases the charge temperature of the intake air, which is very helpful in cold ignition conditions.

How hot do oil pan heaters get?

As a rule, these elements have one drawback related to the uncontrolled heating process. The crankcase temperature can reach a critical point and it will boil. This can be avoided by using a special thermostat. It is used in conjunction with the tan to switch it off when the desired temperature is reached. Some modern elements have a self-regulating operation algorithm that eliminates the need for the thermostat. The temperature can reach 400-500 degrees.

How do you install an oil pan heater?

Flexible silicone heating plates are ideal for mounting on crankcase or engine blocks, can be installed on transmission, gearbox, transfer gearbox, hydraulic tank, fuel tank, centrifugal pumps, etc. The plate should be glued on a flat surface without ribs and jumpers, it is resistant to engine vibration and friction, the plate material is resistant to aggressive media such as oil and fuel, easy to clean.

The silicone plate can be installed in 5 minutes without the need for special service. It is necessary to clean and degrease the engine crankcase, remove the protective layer and glue the plate to the engine crankcase. The plates can be installed not only on the engine, but also on any other technological equipment, for example, for heating tanks with water and other liquids.

The general rule  is that for every liter of lubricant you are trying to heat, you need between 15 and 30 watts of power. You never want to use more wattage then required. This will cause damage to your pan.

  • The heat pad must be installed on a clean, flat, dry surface. Which means that the paint has to be removed. If you can see that the paint is still on the pan, you would actually have to take something like sand paper, a roloc disk, or something of that sort to remove the paint. In doing so, you don’t want to make the surface smooth, you just need to leave it slightly rough so that it aids in adhesion.
  • You need to apply a liberal amount of Permatex 77 BR silicon, or a product similar, to both the pan and the heat pad.
  • Then install the heat pad onto the pan, and apply pressure to remove the excess silicon between the pad and the pan.
  • It will protect your vehicle or piece of equipment from damage on initial start up during those long cold winter nights, and no, this is not to be used as an electric blanket.

Does block heater heat oil?

This element enables the powertrain to be heated not only for easier starting, but also for reducing the load on the battery, the starter, as well as the rubbing vapors inside the engine itself. Currently, there are two main types of engine preheaters.

  • The first is a self-contained liquid heater that runs on fuel.
  • The second type is electric, working from a household electrical network 220 V or regular 12V board. It ensures that the vehicle engine is warmed up to operating temperature. As the motor temperature increases, the viscosity of the motor lubricant decreases and it is easy to start the engine.
