If like me, you forgot to change the timing belt at the last service and it went “ping” while driving to the shops, you may wish to invest in new engine, or at the very least a few new valves, rockers and possibly the cylinder head… If you are sensible and know that it needs changing, then this little guide is for you. Applies to the 1.4 and 1.6 CVH or PTE engine, but can be applied generally to other models too. Pictures and references to Haynes are made in square brackets where appropriate!

REMOVAL INTERFERENCE ENGINE. In the event of Urning belt failure, it is probable that valve to piston damage has occurred. A compression test should be carried out on all cylinders before removing the cylinder head. 1. Disconnect the negative cable from the battery. 2. Remove: – alternator, – RH engine mounting bracket, – spark plugs. 3. Disconnect the engine wire from alternator bracket and adjusting bar. 4. Remove the No.2 timing belt cover. 5. Turn the crankshaft pulley (clockwise) and align its groove with the timing mark “O’ on the No.1 timing belt cover. 6. Check that the hole of the camshaft timing pulley is aligned with the timing mark on the bearing cap. If not, turn the camshaft one full

Camshaft timing belt must be replaced if cylinder head is to be removed or if drive gears, tensioner or coolant pump are to be replaced. 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 2.0″ (50 mm). DO NOT use a camshaft timing belt that has been twisted or bent double, as this will damage reinforcing fibers. 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 reuse a camshaft timing belt if mileage exceeds 45,000 miles. DO NOT use an oil or coolant contaminated timing belt (cause of contamination must be rectified).
