Bosch Glow Plugs are critical for starting up a diesel engine. The pre-heat, starting and post-glow phases of a glow plug’s operation affect not only the start-up function, but the vehicle’s overall performance as well. With a long history of diesel fuel injection expertise and innovation, Bosch engineers manufacture glow plugs to withstand the rigorous demands of today’s diesel engines.
Features & Benefits:
Bosch patented Duraterm® technology enables the glow plug to reach higher temperatures more quickly for fast engine start-up
Nickel-plated rolled threads for increased strength and prevent seizure
Twin Viton® seals Promote longer life by protecting the coils against damage caused by exhaust gases
Replacing and Installing a Bosch Glow Plug
Causes & Conditions of Glow Plug Failure
Causes of glow plug failure:
Leading Cause: Excessive voltage / glow plug overheating causing the casing to swell, split or burst which allows air to enter the coil area causing immediate failure
Improper testing procedure (applying 12 volts directly to a glow plug designed to operate on 6 volts)
Incorrect engine timing
Improper fuel injector spray pattern
Continual cycling of the glow plugs
Signs that it's time to replace your glow plugs:
Vehicle won’t start
Vehicle starts only after excessive cranking
Excessive cranking can cause the engine oil to be diluted with fuel, which could adversely effect the life of the engine.
Vehicle idles roughly after initial start-up
Excessive exhaust emissions after initial start-up.
