This aftermarket replacement glow plug, part number 839336751, is designed to be compatible with a wide range of New Holland, Ford, and Fiat agricultural tractors. As a crucial component in diesel engines, the glow plug plays a vital role in facilitating cold weather starting by preheating the combustion chamber. When temperatures drop, a fully functional glow plug ensures that the fuel-air mixture ignites efficiently, preventing hard starts and reducing engine strain. This non-OEM alternative offers a cost-effective solution for maintaining your tractor's starting performance. It is engineered to meet the operational specifications required for reliable ignition in demanding conditions. Compatible models include, but are not limited to, New Holland TS Series (TS80, TS90, TS100, TS110, TS115), TM Series (TM115, TM120, TM125, TM130, TM135, TM140, TM150, TM155, TM165, TM175, TM190), and TL Series (TL70, TL80, TL90, TL100), as well as Ford New Holland 5610S, 6610S, 7610S, and 8010. Replacing a faulty glow plug with this compatible unit can restore optimal engine starting capabilities, ensuring your machinery is ready for work when you are. Always verify compatibility with your specific equipment model before purchase.
