This engine piston stop features a 14mm thread, offering reliable performance for engine maintenance and repair.

To use this engine piston stop, first make sure your engine is off and cooled down. Then, carefully insert the piston stop into the spark plug hole with the 14mm thread. Gently turn the engine over until the piston stop makes contact with the piston. This will help you accurately set the piston's position. When you're done using it, remove the piston stop gently. Remember to keep the piston stop clean and dry. Avoid using it with excessive force as it could damage the piston or the stop itself. Regularly check the thread for any signs of wear or damage, and if needed, replace it to ensure its continued effectiveness.
