Plug Heater 2666A023

A Plug Heater is an essential engine component designed to preheat the engine block and maintain optimal temperatures in cold environments. It helps improve engine starting performance, particularly in diesel engines, by warming up the coolant or engine oil to prevent cold-start issues. This preheating reduces strain on the engine, minimizes wear, and ensures smoother ignition even in freezing temperatures.

Plug heaters are commonly used in heavy machinery, trucks, agricultural equipment, and other vehicles operating in cold climates. They are easy to install, typically plugging into a standard electrical outlet, and are designed for reliability and durability to withstand harsh conditions. By maintaining a consistent engine temperature, plug heaters not only improve engine efficiency but also extend the overall lifespan of the engine.
