To remove the timing belt, start by disconnecting the negative cable from the battery and removing the coolant overflow tank and windshield washer tank. If applicable, remove the front suspension upper brace from the strut towers. Then, remove the drive belts from the alternator and power steering pump. Loosen the lug nuts on the right front wheel and raise the front of the vehicle, supporting it on jackstands. Remove the right front wheel and inner fender apron. Position the number one cylinder at TDC and support the engine with a jack. Remove the engine movement control rod and its bracket, as well as the spark plugs. Remove the upper timing belt cover and check for installation marks on the timing belt. Rotate the crankshaft pulley counterclockwise 60 degrees BTDC and remove the timing belt tensioner. Relieve tension between the camshaft sprockets and remove the timing belt from the sprockets. If necessary, remove the camshaft sprockets and the upper idler pulley. Remove the crankshaft pulley bolt and remove the pulley. Remove the lower timing belt cover and slip the timing belt guide off the crankshaft. If reusing the belt, check for a mark on the belt adjacent to the drilled mark on the crankshaft sprocket. Remove the no. 1 idler pulley and plate washer using an Allen wrench. If needed, remove the crankshaft sprocket. Finally, remove the lower sprocket retainer.

If needed, remove the crankshaft sprocket.

While preparing for timing belt removal, you should loosen the lug nuts on the right front wheel but leave them in place.

The number one piston's position is verified to ensure that it is at Top Dead Center (TDC) on the compression stroke. This is important for correctly timing the engine.

Apply thread-locking compound to the first two or three threads on the lower (no. 1) idler pulley bolt. Then position the idler pulley and washer and install the bolt. Tighten the bolt.

The coolant overflow tank, spark plugs, drive belts, alternator, engine mount, and engine support rod are removed to access the timing belt and related components.

Before removing the lower timing belt cover, you should remove the upper timing belt cover and gasket, ensuring that the wiring harness is unclipped and pushed back.
