Safety Warnings – please read

· If the engine has been identified as an Interference engine, damage to the engine will occur if the timing belt has been damaged. A compression check of all the cylinders should be taken before the cylinder head (s) are removed.
· Do not turn crankshaft or camshaft when the timing belt/chain has been removed.
· To make turning the engine easier, remove the spark plugs/glow plugs or injectors.
· Observe all tightening torques.
· Do not turn the engine using the camshaft or any other sprocket.
· Disconnect the battery earth lead (check Radio code is available).

· Do not use cleaning fluids on belts, sprockets or rollers.
· Some toothed timing belts are not interchangeable. Check the replacement belt has the correct tooth profile.
· Always mark the belt with the direction of running before removal.
· Do not lever or force the belt onto its sprockets.
· Do not use timing pins to lock the engine when slackening or tightening the crankshaft pulley bolts.
· ALWAYS REFER TO A REPUTABLE MANUFACTURERS WORKSHOP MANUAL.
