Flexible Oil Reservoir Heating Pads

Frequently Asked Questions About Pad Heaters From Wolverine.

Q: What does a Pad Heater look like?
A: Pad Heaters are thin Flexible heating pads built to conform the outside surface of an engine oil sump or any metal fluid reservoir.

Q: How are Pad Heaters installed?
A: Pad Heaters are easily installed by following the step by step instructions and with basic shop tools. Everything needed for a complete installation is included with each heater.

Q: How long has Pad Heaters been on the market?
A: Pad Heaters both Engine Oil and Hydraulic Heaters were released to market in the Spring of 1988 following 3 years of developmental work and testing.

Q: What is the warranty for a Pad Heater?
A: Pad Heaters have a 3 year warranty.

Q: Why is it important to Heat the oil supply?
A: A Heated oil supply results in:
1) Less drag for quicker startup
2) Immediate oil flow to reduce wear
3) Greatly reduced water and acid contamination of oil

Q: How hot does the oil get?
A: Pad Heaters raise oil temperatures to approximate operating levels.

Q: Is a thermostat required?
A: No, when the heater is sized correctly, a thermostat is not required.

Q: Will Pad Heaters burn the oil like immersion type heaters?
A: Pad Heaters apply Heat to the oil through a very large surface area.
Because the temperature of that surface is far below the level that would
damage oil, the result is a gentle and even Heating.

Q: How long does it take a Pad Heater to do it's Heating job?
A: Pad Heaters will generally raise cold oil temperatures by 38°C (100°F) in 1.5 - 2 hours.
Full Heating is usually accomplished in 5-6 hours.

Q: How does a Pad Heaters do a better job of Heating the engine than block heaters or tank type heaters?
A: Pad Heaters put Heat into the oil supply. HEAT RISES to warm important INTERNAL components.

Q: Are the pistons included in the list of Heater INTERNAL components and if so what temperatures are they warmed to?
A: Pistons are generally warmed to 30°C (85°F) or so as governed by variables in engine type and design.

Q: Will a Pad Heaters raise an engines coolant temperature?
Remember HEAT RISES off the heated oil supply.
The crankcase walls along with the cylinder wall, the outer block wall and
the coolant between them create a very effective barrier to the loss of heat to the atmosphere.
Only a small amount of Heat is absorbed by the coolant resulting in a 15-20° increase in coolant temperature.

Q: Can a Pad Heaters be installed on a curved surface?
A: Yes, a Pad Heater can be installed on single plane curves as short as about 1" radius.
They are not to be installed on a compound curve area.

Q: Can a Pad Heater be moved from one engine to another?
A: The installation of Pad Heater is of a permanent nature.

Q: Can a Pad Heaters be installed on the side of a pan?
A: Pad Heaters do a better job installed at the bottom of the sump (HEAT RISES).
However, an installation of the side of a sump or reservoir will yield excellent results.

Q: Can Pad Heaters be used on diesel fuel tanks?
A: We recommend against an installation on a diesel fuel tank due to the possibility of overheating the fuel supply.

Q: Can Pad Heaters be used on transmissions?
A: Yes, Pad Heaters are suitable for all types transmissions.

Q: How do Pad Heaters compare in use of electricity with old style coolant heaters?
A: Pad Heaters , application for application, use less energy than block or tank type coolant heaters.
Pad Heaters are more economical to operate than block heaters. Compare watt ratings.

Q: Will a Pad Heater save me money?
A: YES, Pad Heaters will save you money by increasing engine and starter life. They are maintenance free and use much less electricity than a block heater.

Q: Should the use of any coolant heater presently in place be continued?
A: YES, the use of any block or tank type coolant heaters can be discontinued.

Q: How does Pad Heaters stand up in an environment of grease, oil, dirt and periodic engine cleanings?
A: Pad Heaters are constructed of materials resistant to the effects of oil, grease, dirt and water.
Direct blasts with the pressure washers used in engine cleaning should be avoided.

Q: Are there other available in other voltages?
A: Yes. There are heaters available in 220 volts and 12 volts D.C.
