The manufacturer recommends replacement of the timing belt (and water pump inspection) under normal operating conditions for Accord and Prelude models every 84 months (7 years) or 105,000 miles. If the vehicle is operated in high temperatures (above 110Â

On interference engines, it is very important to replace the timing belt at the recommended intervals, otherwise expensive engine damage will likely result if the belt fails.

Removal & Installation

1.Disconnect the negative battery cable.

2.Remove the cylinder head (valve) and upper timing belt covers.

3.Turn the engine to align the timing marks and set cylinder No. 1 to Top Dead Center (TDC) on the compression stroke. The white mark on the crankshaft sprocket should align with the pointer on the timing belt cover. The words UP embossed on the camshaft sprocket should be aligned in the upward position. The marks on the edge of the sprocket should be aligned with the cylinder head or the back cover upper edge. Once in this position, the engine must NOT be turned or disturbed.

4.Remove all necessary components for access to the lower timing belt cover, then remove the cover.

5.There are 2 belts in this system; the one running to the camshaft sprocket is the timing belt. The other, shorter one drives the balance shaft and is referred to as the balancer shaft belt or timing balancer belt. Lock the timing belt adjuster in position, by installing one of the lower timing belt cover bolts to the adjuster arm.

6.Loosen the timing belt and balancer shafts tensioner adjuster nut, do not loosen the nut more than 1 turn. Push the tensioner for the balancer belt away from the belt to relieve the tension. Hold the tensioner and tighten the adjusting nut to hold the tensioner in place.

7.Carefully remove the balancer belt. Do not crimp or bend the belt; protect it from contact with oil or coolant.

8.Remove the balancer belt sprocket from the crankshaft.

9.Loosen the lockbolt installed to the timing belt adjuster and loosen the adjusting nut. Push the timing belt adjuster to remove the tension on the timing belt, then tighten the adjuster nut.

10.Remove the timing belt by sliding it off the sprockets. Do not crimp or bend the belt; protect it from contact with oil or coolant.

11.If defective, remove the belt tensioners by performing the following:

A.Remove the springs from the balancer belt and the timing belt tensioners.

B.Remove the adjusting nut from the belt tensioners.

C.Remove the bolt from the balancer belt adjuster lever, then remove the lever and the tensioner pulley.

D.Remove the lockbolt from the timing belt tensioner lever, then remove the tensioner pulley and lever from the engine.

This is an excellent time to check or replace the water pump. Even if the timing belt is only being replaced as part of a good maintenance schedule, consider replacing the pump at the same time.

12.If the water pump was replaced, install a new O-ring and make certain it is properly seated. Install the water pump and tighten the mounting bolts to 106 inch lbs. (12 Nm).

13.If the tensioners were removed, perform the following procedures:

A.Install the timing belt tensioner lever and the tensioner pulley.

B.Install the balancer belt pulley and adjuster lever.

C.Install the adjusting nut and the bolt to the balancer belt adjuster lever.

D.Install the springs to the tensioners.

E.Install the lockbolt to the timing belt tensioner, then move it its full deflection and tighten the lockbolt.

F.Move the balancer it's full deflection and tighten the adjusting nut to hold its position.

14.The pointer on the crankshaft sprocket should be aligned with the pointer on the oil pump. The camshaft sprocket must be aligned so that the word UP is at the top of the sprocket and the marks on the edge of the sprocket are aligned with the surfaces of the head or the back cover upper edge.

15.Install the timing belt on the sprockets in the following sequence: crankshaft sprocket, tensioner sprocket, water pump sprocket and camshaft sprocket.

16.Check the timing marks to be sure that they did not move.

17.Loosen, then retighten the timing belt adjusting nut; this will apply the proper amount of tension to the timing belt.

18.Install the timing balancer belt drive sprocket and the lower timing belt cover.

19.Install the crankshaft pulley and bolt, tighten the bolt to 181 ft. lbs. (245 Nm). Rotate the crankshaft sprocket 5-6 turns to position the timing belt on the sprockets.

20.Set the No. 1 cylinder to TDC and loosen the timing belt adjusting nut 1 turn. Turn the crankshaft counterclockwise until the cam sprocket has moved 3 teeth; this creates tension on the timing belt.

21.Tighten the timing belt adjusting nut.

22.Set the crankshaft sprocket and the camshaft sprocket to TDC. If the sprockets do not align, remove the belt to realign the marks, then install the belt.

23.Remove the crankshaft pulley and the lower cover.

24.With the timing marks aligned, lock the timing belt adjuster in place with one of the lower cover mounting bolts.

25.Loosen the adjusting nut and ensure the timing balancer belt adjuster moves freely.

26.Align the rear timing balancer sprocket using a 6 x 100mm bolt or rod. Mark the bolt or rod at a point 2.9 in. (74mm) from the end. Remove the bolt from the maintenance hole on the side of the block; insert the bolt/rod into the hole and align the 2.9 in. (74mm) mark with the face of the hole. This will hold the shaft in place during installation.

27.Align the groove on the front balancer shaft sprocket with the pointer on the oil pump.

28.Install the balancer belt. Once the belts are in place, be sure that all the engine alignment marks are still correct. If not, remove the belts, realign the engine and reinstall the belts. Once the belts are properly installed, slowly loosen the adjusting nut, allowing the tensioner to move against the belt. Remove the bolt from the maintenance hole and reinstall the bolt and washer.

29.Install the crankshaft pulley, then turn the crankshaft sprocket 1 turn counterclockwise and tighten the timing belt adjusting nut to 33 ft. lbs. (45 Nm).

30.Remove the crankshaft pulley and the bolt locking the timing belt adjuster in place.

31.Install the lower and upper timing belt covers, and all applicable components. When installing the crankshaft pulley, coat the threads and seating face of the pulley bolt with engine oil, then install and tighten the bolt to 181 ft. lbs. (250 Nm).

32.Install the rocker arm (valve) cover gasket cover to the groove of the rocker arm (valve) cover. Before installing the gasket thoroughly clean the seal and the groove. Seat the recesses for the camshaft first, then work it into the groove around the outside edges. Be sure the gasket is seated securely in the corners of the recesses.

33.Apply liquid gasket to the 4 corners of the recesses of the rocker arm (valve) cover gasket. Do not install the parts if 5 minutes or more have elapsed since applying liquid gasket. After assembly, wait at least 20 minutes before filling the engine with oil.

34.Install the cylinder head (valve) cover and all other applicable components.

35.Connect the negative battery cable.
