GLOW PLUG

12V Glow Plug M18x1.5 – Original Part Number GV196 for Case IH tractors

An essential component for starting agricultural diesel engines

The glow plug is an indispensable component for the proper operation of diesel engines, particularly on agricultural tractors used in sometimes harsh conditions. Its role is to heat the combustion chamber to facilitate ignition of the air-fuel mixture during startup. In a diesel engine, the self-ignition of fuel depends heavily on internal temperature. When the engine is cold—especially in winter or after a long period of inactivity—the glow plug helps the engine reach the conditions necessary for starting more quickly. This 12V glow plug, with an M18x1.5 thread , corresponds to the original part number GV196. It is intended to replace a worn, defective, or failing glow plug. A glow plug in poor condition can cause difficult starts, excessive smoke when the engine is cold, engine misfires, or abnormal strain on the starter and battery.

Technical Specifications of the GV196 Glow Plug

This glow plug is designed for a 12-volt power supply, a voltage commonly used on many agricultural tractors. Its M18x1.5 thread ensures a proper fit for compatible engines. Before installation, it is recommended to verify the part number of the original equipment, the thread dimensions, and compatibility with the tractor’s engine. The main specifications are as follows:

• Part Type: Glow Plug
• Original part number: GV196
• Voltage: 12V
• Thread: M18x1.5
• Application: diesel engines in agricultural tractors

Thanks to its design, this glow plug improves starting performance and helps protect the tractor’s electrical components—particularly the battery and starter motor—which are subjected to heavy strain when the engine has difficulty starting.

Compatible tractors Case, IH

This glow plug is compatible with certain Case IH tractors, specifically models in the BD series. It may be suitable for the following tractors:

• Case IH D215
• Case IH D217
• Case IH D219
• Case IH D322
• Case IH D324
• Case IH D326
• Case IH D432
• Case IH D436

It is also paired with several types of IH engines, including:

• D148 - IH
• D99 - IH
• D132 - IH
• D74 - IH
• D111 - IH
• D66 - IH

These compatibility listings are provided for informational purposes only. To avoid ordering errors, we recommend comparing the old spark plug with the new one, checking the GV196 part number, and verifying the engine’s technical specifications.

When should a glow plug be replaced?

Several symptoms may indicate that a glow plug needs to be replaced. The most common sign is difficulty starting the engine when cold. If the tractor requires several attempts to start, or if the engine runs unevenly during the first few seconds, the glow plugs may be the cause. White or gray smoke upon startup may also indicate poor combustion due to insufficient preheating. It is recommended to regularly check the condition of the glow plugs, especially before periods of heavy use: haymaking, plowing, seeding, or winter work. Preventive replacement can help avoid having the tractor break down at the wrong time.

A Part Designed for Agricultural Tractor Maintenance

Replacing a glow plug is a routine maintenance task for both older and newer tractors. This part directly contributes to engine reliability and machine uptime. For a comprehensive maintenance check, it may also be helpful to inspect other components related to the tractor’s starting and operation, such as the starter motor, battery, electrical system, and certain hydraulic components. In addition, you can take advantage of a range of parts for farm tractors, including hydraulic parts for tractors, tractor starters, hydraulic cylinders for farm machinery, and seats for farm tractors.

Key Points

The 12V M18x1.5 glow plug (part number GV196 ) is a suitable solution for ensuring reliable starting of compatible Case IH tractors, particularly BD series models equipped with IH engines. Simple yet essential, it contributes to the engine’s longevity and everyday ease of use.
