  • Hints & Tips
    When fitting new glow plugs always test the timer is operating correctly.

    Older engines used a glow period of up to 21 seconds where as more modern engines use around a 6 to 8 second heat period and provide after glow at a reduced voltage. If the pump timing is not correct or the engine is over fuelled this can also damage the glow plugs with increased vibration and heat.

    It is very important to only use the recommended glow plug applications listed in the Bosch catalogue. Glow Plugs are matched to the engine type and timer or control device. Using the incorrect plug can result in the failure of the heating element.

    When replacing glow plugs, have the function of the relay and controller tested.

    On older open coiled systems, make sure all the resistor straps are clean and tight and free from corrosion.

    Always test the vehicle battery condition and capacity as the functtion of the glow plug in affected by low voltage during cranking.
