Installation Instructions

1. Preparation: Begin by disconnecting the vehicle’s battery and lifting the vehicle if necessary to access the engine.
2. Remove Old Bolts: Carefully remove the old timing cover bolts using an appropriate socket or wrench. Be cautious not to damage the timing cover or surrounding components.
3. Install New ARP Bolts: Insert the ARP 12pt timing cover bolts into their respective holes and hand-tighten them.
4. Torque the Bolts: Using a torque wrench, tighten the bolts in a crisscross pattern to the manufacturer’s recommended torque specification (usually between 12-15 ft-lbs).
5. Recheck Fitment: Ensure the timing cover is securely fastened and there are no gaps or leaks before reassembling any other components.

Note: Professional installation is recommended if you're not familiar with engine components, particularly in high-performance or racing builds.

Maintenance Tips

• Regular Inspections: Periodically check the timing cover bolts for any signs of loosening or damage, especially after high-performance driving or engine work.
• Proper Torque: Always ensure bolts are torqued to the recommended specifications to prevent leaks or cover misalignment.
• Avoid Over-tightening: Over-tightening can cause thread damage or even break the bolts, so always follow the recommended torque settings.
• Corrosion Prevention: Keep the engine bay clean and dry, as excessive moisture can cause rust or corrosion over time, especially around the timing cover area.
