FAQs
What is the primary function of a glow plug?
A glow plug is a heating device used in diesel engines to preheat the combustion chamber, aiding in ignition when the engine is cold.
How do I know if my glow plugs need replacing?
Symptoms include hard starting (especially in cold weather), rough idling, increased exhaust smoke, and a check engine light. It's best to have them tested by a mechanic.
What is the thread size of the NGK 4602 glow plug?
The thread size is M12 x 1.25mm.
What is the recommended tightening torque for this glow plug?
The recommended tightening torque is 23 Nm.
How many glow plugs do I need for my vehicle?
This depends on the number of cylinders in your diesel engine. The NGK 4602 is sold as a single unit, so you will need one for each cylinder requiring a glow plug.
Can I use these glow plugs in a gasoline engine?
No, glow plugs are specifically designed for diesel engines. Gasoline engines use spark plugs.
What does the 'Y-909R' designation mean?
Y-909R is the trade number designation for this specific NGK glow plug model (4602).
Troubleshooting
Engine struggles to start in cold weather
This could indicate a faulty glow plug. Ensure the glow plug system is receiving the correct voltage (11v) and that the glow plug itself is not damaged or worn out. Check for proper connection at the M5 connector.
Check engine light related to emissions or starting system
A failing glow plug can trigger diagnostic codes. Have the vehicle's diagnostic system scanned to confirm if the glow plug circuit or performance is the cause.
Difficulty during installation
Ensure the thread size (M12 x 1.25mm) and dimensions (length 76.5mm, fitting depth 29mm) match the engine's requirements. Do not force the glow plug; if it doesn't thread easily, re-check compatibility and alignment. Ensure correct tightening torque (23 Nm) is applied.

Setup, Compatibility & Care
Compatibility Check: Before purchasing, it is crucial to verify that the NGK Glow Plug 4602 is the correct part for your specific vehicle make, model, and year. Refer to your vehicle's owner's manual or consult an automotive professional if unsure.
Installation: This glow plug has specific technical data including a thread size of M12 x 1.25mm, an overall length of 76.5mm, and a fitting depth of 29mm. It requires a hex nut size of 12mm and must be tightened to a torque of 23 Nm. The voltage is 11v and the rated current is 5.5A. Ensure installation is performed by a qualified mechanic to avoid damage.
Care: Glow plugs are a wear-and-tear component. While they do not require regular cleaning in the same way as filters, their performance can degrade over time. Ensure no foreign debris enters the cylinder head during installation. The "No Leak Guarantee" mentioned in customer feedback suggests that if any damages occur during transit or fitting related to the seal, replacement is typically provided.
