Steps
Remove engine covers and belt
Remove the upper cam cover and move the power steering reservoir aside. Record the accessory belt routing, release its tensioner, and remove the serpentine belt.
Remove timing covers and wheel access panel
Remove the timing cover fastener and lift the cover away. Raise and support the vehicle, remove the right front wheel, and remove the inner access panel.
Set engine timing marks
Rotate the crankshaft by hand to the specified timing position. Confirm the camshaft and crankshaft marks align with their reference points before releasing the old belt.
Remove the old belt and idler
Note the tensioner position and loosen its fastener to release belt tension. Remove the belt without rotating either camshaft or crankshaft, then remove the idler pulley if replacing it.
Install pulleys and new timing belt
Fit the new idler and tensioner using the correct locating tabs. Route the new belt around the crank and cam pulleys with the timing marks aligned and slack kept on the tensioner side.
Set belt tension
Adjust the tensioner using the specified tool and procedure. Tighten its fastener to vehicle specification and recheck that none of the timing marks shifted during installation.
Rotate engine and recheck timing
Turn the crankshaft slowly by hand through two complete revolutions. Return it to the reference position and confirm the crank and cam marks align exactly before proceeding.
Reinstall covers and accessory belt
Reinstall the timing covers, inner panel, and wheel. Route the accessory belt according to its diagram, restore the reservoir and cam cover, and verify all tools are clear.
Start and inspect
Start the engine only after timing marks are confirmed. Listen for abnormal noise and check belt tracking, then shut down and inspect the work if anything sounds incorrect.
Check your vehicle’s repair manual for exact specifications and fit.
