remove air filter box and hoses to inlet manifold. remove timing belt cover. line dots on all 4 camshaftand crankshaft. mark in position with a bit of paint. use a device to prevent the camshaft from moving, note the way the belt is loop on all cams.lossen tensioner this will release belt for removal.
Make sure you have a timing belt kit so you replace tensioner as well. this is what destroy my engine.--------
Get a manual for the V6 omega or the Saab this will explain it all. It is the same engine.
