Glow plugs are responsible for preheating the air in the engine's combustion chamber before the diesel fuel is injected. This preheating process is crucial to ensure the fuel is ignited efficiently, and the engine runs smoothly.

If the glow plugs are not functioning correctly, the engine may struggle to start, which can lead to incomplete combustion and decreased fuel economy. The engine may also experience a decrease in power and acceleration due to the inefficient combustion of fuel.

Regular maintenance of the glow plugs, such as cleaning or replacement when necessary, can help ensure the engine runs smoothly and efficiently. It is important to use high-quality glow plugs that are designed for the specific make and model of the Duramax engine to ensure optimal performance.

The glow plugs in your Duramax diesel engine are designed to heat the combustion chamber before the engine is started, which aids in starting the engine in cold temperatures.
