The timing chain cover IS the oil pump. You need to remove the dampener pulley (that's the pulley that drives the serpentine belt) then you can remove the timing chain cover/oil pump.
In order to replace a timing chain for a 2003 Chevy Cavalier, a person will need remove the oil pan, crankshaft pulley and hub, timing cover bolts, and timing cover. Then the timing cover gasket, timing cover and bolts, crankshaft pulley, and oil pan will need to be installed.
just remove the water pump not the timing cover
Remove 1 Auxiliary Drive Belts. 2 LH top engine mounting. 3 Crankshaft Pulley 4 Cylinder head cover 5 Timing belt upper cover 6 Timing belt lower cover
Disconnect the negative battery cable. Turn the crankshaft until the No. 1 cylinder is at TDC on the compression stroke with the timing marks aligned. Remove the idler pulley and bracket assembly. Remove the drive and accessory belts. Remove the radiator and water pump Remove the crankshaft pulley and damper Remove the lower radiator hose. Remove the oil pan-to-timing cover bolts. Remove the front cover bolts and the front cover. Tap the cover lightly with a plastic mallet, if necessary, to break it loose.
CAUTION: Some models are equipped with anti-theft-radio make sure you have the activation code before disconnecting battery * Disconnect the negative battery cable * Rotate the engine in the normal direction of rotation (clockwise) until the No.1 cylinder is located TDC * Remove the accessory drivebelt * Loosen the water pump pulley bolts and then remove the water pump pulley * Using a chain wrench or a strap wrench to hold the crankshaft pulley loosen the crank pulley bolt and then remove the pulley bolt and the crank pulley.Make sure that you dont move the no.1 cylinder from TDC while loosening the crank pulley bolt.After removing the crankshaft pulley remove the timing belt retainer/guide flange * Remove the four upper timing belt cover bolts and then remove the upper timing belt cover.Remove the lower timing belt cover bolts * Make sure that the timing belt camshaft sprocket timing marks are aligned with the top cylinder head * Remove the timing belt tensioner pulley bolt and then remove the tensioner pulley * Remove the timing belt
disconnect negative battery cable rotate the engine in the normal direction of rotation(clockwise)until the no.1 is TDC remove the accessory drivebelt loosen the water pump pulley bolts and then remove the water pump pulley using a chain wrench or a strap wrench to hold the crankshaft pulley,loosen the crank pulley bolt and then remove the pulley bolt and the crank pulley.Make sure that you dont move the No.1 cylinder from TDC while loosening the crank pulley bolt.After removing the crankshaft pulley remove the timing belt retainer/guide flange remove the 4 upper timing belt cover bolts and then remove the upper timing belt cover.Remove the lower timing belt cover bolts make sure that the timing belt camshaft sprocket timing marks are aligned with the top of the cylinder head if your planning to re-use the timing belt put a directional arrow indicating the normal clockwise direction of rotation on the belt remove the timing belt tensioner pulley bolt and then remove the tensioner pulley remove the timing belt remove the timing belt idler pulley bolt and then remove the idler pulley if the camshaft sprocket is damaged or must be removed to replace the camshaft seal or to strip the cylinder head for overhaul use a wrench to hold the cramshaft in place and then remove the sprocket retaining bolt.Then remove the camshaft sprocket from the end of the camshaft remove the crankshaft tioming belt sprocket
1.Disconnect the negative battery cable 2.Rotate the engine in the normal direction of rotation (clockwise)until the no.1 cylinderis located at TDC 3.Remove the accessory drivebelts 4.Loosen the water pump pulley 5.Using a chain wrench or a strap wrench to hold the crankshaft pulley,loosen the crank pulley bolt and then remove the pulley bolt and the crank pulley.Make sure that you dont move the no.1 cylinder from TDC while loosening the crank pulley bolt.After removing the crankshaft pulley,remove the timing belt retainer/guide flange 6.Remove the four upper timing belt cover bolts and then remove the upper timing belt cover.Remove the lower timing belt cover bolts 7.Make sure that the timing belt camshaft sprocket timing marks are aligned with the top of the cylinder head. 8.Remove the timing belt tensioner pulley bolt and then remove the tensioner pulley 9.Remover the timing belt
the cam timing mark is behind the belt front cover,take it off and you will see the mark on the drive cog,the alignement mark is on the back cover at the top. the other timing mark(crank shaft)is behind the pulley,there are no marks on pulley. to align them properly you need to remove the bottom pulley (crankshaft),remove the timing belt cover and timing belt,then align each pulley to their marks,refit bottom pulley and timing belt and check that marks are still aligned on respective positions. if they have moved,take belt off top pulley,aligne marks,refit belt,check again for mis-alignement.one tooth out is allowable on one pulley if o/k refit front cover,start her up.
Impossible to answer as you failed to list make, model, year, and engine size.
Yes, along with the belts, intake, crank pulley, timing chain cover, timing chain, and chain guides.
ca20? remove all the belts, water pump pulley, underdrive pulley, timing chain cover and timing belt and the water pump is accessible. I would replace the timing belt too.
