859854 Glow Plug | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta glow plug from the Starting System group, weighing 0.029 kg and listed for 9 applications across the TMD, MS, TAMD and MD engine series. Cable 859855 carries the same nine applications and is the link that feeds it, so the two are usually handled as one job.

🔌 Function

Heats the combustion chamber before cranking so a cold engine will fire and run cleanly from the first revolutions.

⚠️ Common Signs of Failure

• Hard starting from cold that clears once the engine is warm
• White smoke and a rough, uneven first minute of running
• One cylinder that clearly comes in later than the rest on a cold start
• Blown fuse or a preheat warning that stays on
• Plug found with a swollen, eroded or broken tip on removal

🛠️ Service Notes

• Test the whole set rather than one plug — they age together, and a single new plug beside four tired ones changes very little
• Work on a cold engine and back the plugs out gently; a seized plug in a hot head is easily snapped off
• Check the feed cable and its terminal at the same time, since a poor connection mimics a failed plug
