The Most Effective Way to Heat an Engine
Engine block heaters and oil pan heaters warm the engine fluids of gas and diesel engines. Immersion heaters operate using AC power and the heat generated, which distributes throughout the engine or oil pan by convective flow of the warmed fluid.
The thermostat measures the coolant temperature and regulates the engine block heater by cycling the heater on and off according to the temperature range setting of the thermostat, saving you money. Approved to North American and European electrical standards, PTI immersion heaters are designed and tested for each individual engine application.
