How to install a Ford Racing Hot Rod Performance Camshafts on your 2005-2010 Mustang

NOTES:

• Purchase new VCT solenoid attachment bolts (as they are not reusable) and Silicon Gasket Sealant from a Ford Dealer. It is not recommended to use any other gasket sealant.
• If doing the work in vehicle, purchase the special service tools required in the service procedures below from a Ford Dealer.

a. The Wedge Tool is needed to hold the timing chain in place so the front cover does not have to be removed. This will save you a lot of time and work if you are working on an engine in a vehicle.

b. If you are doing a new engine build-out of a vehicle, you will not need these tools.

• Follow service procedures to remove ignition coils, oil level indicator, valve covers and camshafts.
• Replace camshafts with Ford Racing camshafts:

a. RH camshaft p/n: XE-6251-309994

b. LH camshaft p/n: XE-6C255-309995

• Follow service procedure to install Ford Racing camshafts, valve covers, dipstick, ignition coils and air induction system.
• Verify there are no oil or air leaks and all electrical connections are made.
• Have a qualified person recalibrate the PCM to realize maximum performance improvement.
