CAUTION: Do not rotate crankshaft or
camshafts with timing belt removed.
CAUTION: Camshaft timing belt must be
replaced if cylinder head is to be removed or
new drive gears, tensioner or coolant pump
are to be fitted. Camshaft timing belts must
be stored and handled with care. Always
store a camshaft timing belt on its edge with
a bend radius greater than 50 mm (2.0 in).
Do not use a camshaft timing belt that has
been twisted or bent double as this will
damage the reinforcing fibres. Do not use a
camshaft timing belt if debris other than belt
dust is found in timing belt covers. Do not
use a camshaft timing belt if partial engine
seizure has occurred. Do not use a
camshaft timing belt if mileage exceeds
72,000 km (45,000 miles). Do not use an oil
or coolant contaminated timing belt, cause
of contamination must be rectified.
