Good Maintenance Practices:

Before purchasing and installing an engine timing chain kit, make sure it is the correct size and fit for your vehicle.
Be sure to have timing marks aligned when installing timing chain.
Have your vehicle inspected as soon as possible if the 'Service Engine Soon' light illuminates.
Have your vehicle inspected immediately if the 'Service Engine Soon' light flashes rapidly, as this could indicate an engine misfire condition which may damage your engine and/or engine emission components.
Regularly inspect timing chain kit for signs of damage or wear, and replace them if signs of damage are found.
