Glow Plug
CAUTION:
The glow plugs operate on a 4.4-volt system. The glow plugs DO NOT tolerate any over voltage. Full battery voltage will destroy the glow plug immediately. DO NOT test the glow plugs with a 12V source as damage will occur to the glow plug.
CAUTION:
- Never bend, bump or knock the fast metallic glow plugs.
- Fast metallic glow plugs must not be handled loose in a container. Store, handle, and transport them only in original boxes.
- If there is any doubt about the proper condition of a glow plug, do not reuse it.
- Do not clean the glow plugs with abrasive or aggressive media.
- Avoid dipping the glow plug into fluids.
- Read Diagnostic Trouble Codes (DTCs). If a glow plug problem is indicated, do not start the engine.
CAUTION:
Disregarding these instructions may cause severe engine damage.
Glow plugs are used to help start a cold or cool engine. The glow plugs will heat up and glow to heat the combustion chamber of each cylinder. An individual glow plug is used for each cylinder.
