Glow Plug: Testing and Inspection
Glow Plugs Inspecting
Glow Plugs Inspecting
Burnt electrodes in glow plugs are frequently caused by malfunctioning Fuel Injectors. Damage of this nature is not caused by malfunction of the
glow plugs.
If inspection reveals glow plug damage as shown (-arrow-), replacing the glow plugs is not sufficient. The Fuel Injectors must also be tested for
opening pressure and leakage.
