The timing belt and crankshaft sprocket must be therefore detached. Carefully insert a screwdriver or a seal removal tool and loosen the seal from the engine without causing any scratches on the housing bore or damaging the crankshaft because with the new seal, if either of them is done, there will be leakage. Wipe the oil seal bore and spread a thin layer of OE oil on the new seal because it eases installation, the multi-purpose grease should then be applied on the seal lip. The seal-driver or a socket slightly smaller than the outside diameter of the seal is to be used to drive the new seal as squarely and to the same depth as the original as possible; if no socket is available, a short length of large pipe may be used. After installation look at the seal opening and make sure garter spring is not hang out. Torque the crankshaft sprocket and then the timing belt back on, take the car for a test drive to look for oil leakage at the front seal.
