DOs:

1. DO choose the appropriate thread locker for spark plug thread repair insert. Consider the specific requirements of your application.
2. DO use red high temp thread lockers, such as Time-Sert 6020 and Seal Tite 266, for spark plug inserts. These provide a strong and secure bond that can withstand high levels of vibration and heat.
3. DO apply a modest quantity of thread locker. These anaerobic thread lockers are designed to fill small gaps, so using too much can result in spreading beyond the required surfaces.
4. DO thoroughly clean the threads before applying the thread locker. Removing any contaminants, grease, dirt, or oil will ensure proper adhesion.
5. DO allow the thread locker to fully cure. It is best to wait for 24 hours after application for optimal performance.

DON’Ts:

1. DON’T use blue thread lockers for spark plug inserts. Blue thread lockers are typically low-strength and not suitable for applications that require a secure bond under high vibration and heat.
2. DON’T apply green thread lockers directly to the insert before installation. Green thread lockers are thin and can spread too thinly, leading to insufficient coverage and a weaker bond.
3. DON’T use super glue to hold spark plug inserts. Super glue lacks the vibration resistance required for engine applications and may weaken or fail over time.
4. DON’T apply any thread locker to the spark plug itself. Using thread locker on spark plug threads can make it difficult to remove the spark plug in the future and potentially damage the threads or cause breakage.
5. DON’T assume that thread locker affects grounding. Thread locker on the external threads of a spark plug insert does not prevent proper grounding because it only fills gaps and allows sufficient metal-to-metal contact.

Additional Tips:

1. Apply thread locker on taper seat spark plug inserts and washer seat inserts for additional security and strength.
2. Ensure the thread locker bottle is properly sealed after each use to prevent air from entering and affecting its performance over time.

Remember, it’s important to choose the right thread locker, apply it correctly, and follow the manufacturer’s instructions for the best results in spark plug thread repair insert applications.
