Timing Belt: Service and Repair

1. Remove timing cover.

Fig. 11 Timing Belt Tensioner Assembly:

2. Remove timing belt tensioner pulley attaching bolt, then the tensioner pulley, spring and spring cover.
3. If reusing old belt, mark direction of rotation on belt to aid installation.
4. Remove timing belt from crankshaft and camshaft sprockets.
5. Check crankshaft and camshaft sprockets, tensioner pulley, and timing belt for wear or damage. Replace components as necessary.

Fig. 12 Valve Timing Mark Alignment:

6. Align camshaft and crankshaft sprocket timing marks with marks on cylinder head and oil pump housing.
7. Install timing belt. If reusing old belt, ensure belt is installed so that direction of rotation mark made during removal is positioned correctly.
8. Install spring and spring cover onto tensioner pulley, then install pulley and attaching bolt. Do not tighten bolt at this time.
9. Install tensioner spring onto anchor tightening pulley attaching bolt to 19-26 Nm (14-19 lb ft).
10. Time camshaft and crankshaft as follows:
a. Align crankshaft pulley timing notch with TC mark on timing belt cover tab.
b. Remove upper timing cover.

Fig. 13 Camshaft & Crankshaft Valve Timing Marks:

c. Camshaft timing marks should be aligned. If camshaft timing cannot be viewed, rotate crankshaft pulley one revolution, aligning notch with timing cover TC mark.
d. If camshaft timing marks are aligned, the camshaft is properly timed to the crankshaft.
11. Reinstall timing cover.
