Adjustment
Valves should be adjusted cold when the cylinder head
temperature is less than 100°F (38°C).
Adjustment is the same for both intake and exhaust
valves.
Adjust valve clearance at TDC of each cylinder.
Do not rotate the engine counterclockwise. The tim-
ing belt could jump a tooth on the camshaft pulleys.
