A car timing belt keeps the engine running smoothly. It makes the crankshaft and camshaft valves open and close in time with the pistons. The owner's manual for the 1997 Honda Accord recommends the timing belt for a 1997 model should be replaced after 105,000 miles. It is worth checking regularly for damage, as it may require replacement sooner.
Remove the negative cable from the battery.
Line up the crankshaft to match up with the timing belt match marks, as well as with cylinder one at the top, center of the compression stroke.
Fasten the belt adjuster, using a bolt from the lower timing belt cover on the arm of the adjuster.
Loosen the timing belt and balance shaft nut. Push the balance belt tensioner away from the timing belt to reduce tension. Slip the balance belt from the pulleys; do not crease or bend it.
Disconnect the crankshaft balance belt drive.
Undo the timing belt adjuster lock-bolt, and loosen the nut. Push on the the adjuster, relieving tension on the timing belt. Slip the timing belt from the pulleys, and discard.
Align the crankshaft timing pointer with the camshaft pulley and the flywheel, so you can see the word "Up" at the top. The edge-marks should also line up with the head surface.
Put the belt over the tensioners and pulleys. Turn the crankshaft counterclockwise to make the cam pulley rotate through three teeth, and line up the timing belt marks.
Connect the crankshaft and balancer belt-drive sprocket. Align the front and rear balancer pullets with the body of the oil pump. Mount the balance belt.
All engine alignment marks must be accurate. Turn the crankshaft one complete cycle, and lock in place. Loosen the bolt that is locking the tensioner.
Replace the bottom timing belt cover. All the rubber seals must be in position. Put in a new seal to surround the adjusting nut.
Place the crankshaft key, and put in the pulley. Grease the bolt threads, and secure at 181 foot-pounds. Replace the top cover, and secure the bolt to 40 foot-pounds.
Reattach the negative battery.
