Glow Plug Operation:
Once engine starting is initiated by driver, the Glow Plug's Heater Tube is energized and goes rapidly to over 1400 Degrees F. This high temperature ignites the diesel fuel which causes combustion which then start the engine. "Post Glow" (typically 3 minutes) takes place after engine starting. "Post Glow" is essential to minimize warm up time and reduce toxic emissions. Diesel Engine Glow Plugs have a Lifespan of about 100,000 miles.
Signs of a Worn-out Glow Plug:
- Difficulty Starting Engine when Cold
- Misfiring Engine
- Slow Acceleration
- Black or White Smoke coming out of Tail Pipe
- Poor Fuel Mileage
Testing Resistance of a Diesel Glow Plug:
- Disconnect Connector Wire & remove Glow Plug
- Clean Plug Threads & any carbon built-up
- Using a Multimeter, check Ohms Resistance between Plug Threads & Connector End
- Acceptable Resistance is between 0.1 & 6 Ohms. 0.7 - 0.8 Ohms is ideal
