How to Replace a Timing Belt on Carsby Contributing Writer
A timing belt is an important component of your vehicle so replacing it in due time is a top priority. The engine crankshaft uses a drive sprocket via a timing belt to connect to the larger camshaft so it is necessary to always check if the timing belt is worn out and needed to be replaced. This is one component of your Hyundai car that needs to be replaced entirely when damaged and not just repaired by keeping it together.

Place your vehicle on lifts. You are going to access the underside of the vehicle and the additional working space is helpful.
Remove the power cables on the top of the Chevy HHR's battery, than take off the distributor cap.
Twist the crankshaft bolt on the side of the engine until the small timing mark on the crankshaft aligns with the zero degree mark on the timing belt cover.
Take off the bolts around the timing cover plate. This plate is used to protect the timing belt. Once the bolts are off, slide the cover plate out.
Apply your torque wrench to the timing belt tensioner and loosen the connection. You don't want to completely remove the tensioner, so do not remove the bolt completely. Repeat the same process with the mounting bolt next to the tensioner bolt. With the mounting bolt lose, pry the tensioner off the timing belt, then tighten the mounting bolt. You are now able to slide off the old timing belt from your Chevy HHR.
Slide the replacement timing belt into position and loosen the holding bolt. You can then slide the new timing belt into position. Tighten the holding bolt and the tensioner. Place the timing belt cover back onto the vehicle and secure all the bolts you removed from the vehicle.
Items you will need
Jack the vehicle up and support it with jack stands. Remove the splash guard, the radiator, cooling fan, accessory belts, thermostat water hose, water pump pulley, distributor cover and the air intake tube on the valve cover.
Remove the crankshaft pulley bolt and the crankshaft pulley. Remove the top and bottom timing belt covers. Once the covers are removed, screw the crankshaft pulley bolt back in. Turn the crankshaft until the Number 1 cylinder is on top dead center. The timing marks should be lined up. Timing marks are located on the camshaft pulleys and the crankshaft.
Loosen the timing belt tensioner nut. Turn the tensioner clockwise with an Allen wrench. Tighten the tensioner nut---this will keep the tensioner out of your way while you are removing and replacing the timing belt. Remove the timing belt.
Check to see that the timing marks are still properly lined up. Starting at the crankshaft sprocket and moving counterclockwise, wrap the timing belt around the camshafts. Make sure the timing belt is tight between the sprockets on the opposite side of the tensioner.
Loosen the tensioner nut. Use an Allen wrench to keep the tensioner from moving while you loosen the nut. Turn the tensioner clockwise about 70 degrees and temporarily tighten the tensioner nut. Turn the crankshaft clockwise two complete turns. At the end of the second turn, the timing marks should line up again. If not, remove the belt and repeat Steps 4 and 5.
Put 22 pounds of pressure (with your hand) on the timing belt by pushing in on it at the half-way point between the tensioner and the left camshaft pulley. Hold the tensioner with an Allen wrench and loosen the tensioner nut. Insert a feeler gauge between the tensioner pulley and the belt. If your vehicle year is 1997 or older, the space between the belt and the pulley should be 0.014 ins thick by 0.5 ins. wide. If your vehicle is a 1998 or newer, the space should be 0.020 ins. thick by 0.5 ins. wide.
Turn the crankshaft clockwise (slowly) until the feeler gauge moves up to the 1 o'clock position of the tensioner pulley. It will be between the pulley and the belt. Hold the tensioner with the Allen wrench, then torque the tensioner nut to the following specifications:
32-43 foot pounds of torque: 3.3 engines 32-43 foot pounds of torque: 3.0 engines up to 1996 58 to 65 foot pounds of torque: 3.0 engines from 1997 and on
Turn the crankshaft (slowly) clockwise to remove the feeler gauge. Remove the feeler gauge and turn the crankshaft until Number 1 cylinder is at top dead center and the timing marks line up. Use your hand to put pressure on the timing belt between the two camshaft sprockets. The belt should move 0.50 to 0.60 inches. If not, repeat Steps 6, 7 and 8.
Remove the crankshaft pulley bolt. Reinstall all of the components in the order you removed them. Replace the crankshaft pulley bolt when you replace the pulley. Torque the crankshaft pulley bolt to 95 foot pounds of torque if the year of your vehicle is 1993 or older. Torque the crankshaft pulley bolt to 150 foot pounds of torque if the year of your vehicle is 1994 or newer. Refill the radiator.

Remove the lower timing belt cover by unfastening the bolts with a socket wrench and pulling the cover away from the engine.
Use the belt removal tool on one of the camshaft sprockets and turn it clockwise to loosen the timing belt, then slide it off the sprocket.
Detach the vibration/damper pulley located between the camshafts and crankshaft with a socket wrench, and then set it aside.
Turn the crankshaft with a socket wrench by turning the bolt in the center of the sprocket clockwise until the marks on the sprocket are pointed vertically downward and the marks on the camshaft sprockets are pointed horizontally toward each other.
Lock the camshafts into place by positioning the locking tool between the two camshafts, then loosen the tensioner pulley with the socket wrench and remove the timing belt.
Position the new timing belt over the crankshaft and attach a new tensioner pulley to the engine block with a socket wrench; adjust the tension using the Torx bolt provided with the pulley.
Remove the fastening bolt on the new tensioner pulley and tighten the tension to 20 to 22 foot pounds with a torque wrench.
Loop the timing belt over the two camshafts and reattach the vibration dampener pulley; use a torque wrench to tighten the pulley to 20 foot pounds.
