When the timing belt is replaced, the water pump and the timing belt tensioners should always be replaced at the same time. To remove the timing belt, put your engine in TDC position on cylinder number one and disconnect battery. Then remove drive belts and other parts like air intake ducts as well as air filter housing that are necessary. Remove the engine cooling fan(s) and shroud then use a breaker bar with socket to take out bolt from crankshaft pulley. Use hand or screwdriver to take off crankshaft pulley. For non-turbocharged engines, get rid of outer belt covers and also the guide for timing belt. Rotate crankshaft until marks on sprockets align with notches on inner timing belt cover, oil pump and cylinder head seam. Mark these alignment marks together with direction of rotation using paint.Remove idler pulley and sprocket then take away timing belt. If sprockets have to be changed out, remove crankshaft pulley sprocket, camshaft sprockets and also timing belt tensioner.For turbocharged versions eliminate outer timing belts guides including covers.Turn crankshaft so that grooves on sprockets are aligned with notches on backside of timing belts cover or rear cover of cylinder's head.Mark these alignment marks along with how this band spins or changes with paint.Introduce locking devices into camshaft sprocket locations alongside removal idler pulley; thereafter do away with another device known as toothed one.To replace damaged wheels only which include crank shaft one together with a few others like that belonging to timer's tape tensioning gear pull out all such pieces.Carefully inspect tensioner and idler for roughness, backlash etc, examine condition of timer's tape-presence/absence of lateral cracks, signs wear due to operation.Follow relevant steps for models without turbo chargers or turbo charged when putting new rubber on. Finally install crankshaft pulley and all others such as covers of timer's tapes. Include the above remaining steps in this process too.
