12V Heater Plug with 7/8 Inch UNF Thread for Diesel Engine Cold Starting SKU: QT2666103R
Thumbnail Filmstrip of 12V Heater Plug with 7/8 Inch UNF Thread for Diesel Engine Cold Starting Images
When diesel tractors refuse to start on cold mornings, worn-out heater plugs are usually the culprit. These plugs pre-heat the combustion chamber so diesel fuel ignites reliably instead of leaving you cranking endlessly while wearing out your starter.
Why This Part Matters
- Reduces cranking time that wears out starters and batteries
- Eliminates white smoke and rough running during cold starts
- Old-type design with 7/8 inch UNF thread for vintage diesel equipment
- Quality construction heats quickly and handles thermal cycling
Whether you're maintaining older farm equipment or need reliable winter starting for vintage diesel engines, this 12V heater plug delivers the pre-heat assistance that keeps your operation running when cold weather hits. Call S&H Parts if you need help confirming thread specifications for your specific engine.
