Install an Upgraded Hydraulic Timing Chain Tensioner

1. Ensure the engine is completely cool and disconnect the battery. 2. Remove any necessary components, such as the valve cover or access port, to reach the hydraulic tensioner. 3. Depress the locking mechanism on the tensioner to retract the plunger and remove the mounting bolts. 4. Install the upgraded tensioner unit, ensuring the O-ring or seal is properly seated to prevent oil pressure loss. 5. Release the tensioner locking pin to engage the chain guide. 6. Reassemble removed components and perform an oil change with the manufacturer-specified oil viscosity to ensure proper hydraulic pressure. 7. Confirm the fix by monitoring for noise during the first cold start of the following day.
