Installation Instructions:

1. Preparation: Ensure the engine is cool and the vehicle is parked on a flat surface. Disconnect the battery before beginning the installation.
2. Remove Old Cams: Remove the valve cover, timing belt, and other components obstructing access to the camshaft.
3. Install New GSC Cams: Carefully remove the old camshaft and install the new GSC P-D S2 Cams into the camshaft position, ensuring proper alignment and fitment.
4. Adjust Timing: Set the timing to the recommended specifications for optimal performance. Make sure the camshaft timing is correct before reinstalling the timing belt.
5. Reassemble: Reinstall the timing belt, valve cover, and other components in reverse order of removal.
6. Check Valve Clearance: Ensure the valve clearance is set correctly to avoid interference or damage.
7. Test: After installation, start the engine and verify that it runs smoothly. Perform a road test to ensure the cams provide the expected performance gains.

Maintenance Tips:

• Regular Tuning: Regularly check and adjust the engine tuning to ensure the cams continue to perform optimally as your engine components wear in.
• Check Timing: Periodically check the cam timing to ensure it has not shifted, especially after prolonged use or modifications.
• Monitor Engine Health: Keep an eye on engine health with regular oil changes and monitoring of exhaust gas temperatures (EGT) to ensure the engine is running efficiently.
