Wolverine Heaters Engine Oil Pre Heater
Wolverine oil pre-heaters offer a simple to fit yet highly effective solution to preheating the oil in your engine or transmission prior to initial start up. The low profile heater pads are designed using aerospace technology and attach to the sump pan or dry sump tank via the 'peel and stick' highly adhesive backing. Heat up time is 45-90 minutes depending on ambient temperature and the wolverine pads are capable of raising the oil to near full operating temperature. The benefits of this are -
- Improved cold starting (less strain on starter motor and battery)
- Reduces cold start wear
- Provides immediate lubrication
- Reduces emulsification in the oil
- Full operating temperature is reached far quicker
- Improves Engine component life
How To Install

For wiring purposes the centre wire (green / yellow) is wired to earth pin and the other two wires are to live and neutral (it doesn't matter which way round they are wired).
