MAN 65268030012 Glow Plug

Description

The MAN 65268030012 is a glow plug, a critical component in diesel engine starting systems. Glow plugs heat the combustion chamber to aid ignition, particularly in cold weather. This part is used in diesel engines to ensure reliable starts and reduced emissions. The glow plug’s rapid heating capability improves combustion efficiency and reduces white smoke during startup, resulting in smoother operation and increased engine life. It measures 14 x 14 x 162 mm.

Key Features & Benefits

These little guys are basically tiny electric heaters inside your engine. They heat up the combustion chamber—the space where the fuel and air mix—to get things started, especially when it’s cold. They’re a resistive heater, meaning electricity flows through them and creates heat. It’s a pretty simple idea, but crucial. They're most important in diesel engines. Diesels don’t have a spark plug like a gas engine. Instead, the extreme heat from the glow plug ignites the fuel. When you turn the key, the glow plugs preheat that air, and that makes it possible for the diesel fuel to ignite on compression. They usually only run for a short time when starting, and sometimes briefly after, depending on the engine and the temperature. After the engine is warm, they typically aren’t needed.

Symptoms, Risks & Replacements

If a glow plug goes bad, your engine will be really hard to start, especially in cold weather. It might start eventually, but it’ll be struggling. You’ll notice if it's taking a long time to fire up, or if it's running really rough when it does. They act like a shield against cold starting issues. If multiple plugs fail, it may not start at all. They’re relatively inexpensive parts, and replacing them proactively can save you a lot of headaches down the road. We often see folks get a set of them replaced together, since they tend to wear out around the same time. You can find glow plugs and a lot of other engine parts at places like Fixparts Online, but we keep a good stock here too.
