Components removal is usually done after disconnecting the cable, with reference to the battery's negative terminal, draining of the cooling system and the engine oil. Then, take off the air filter housing, resonator, air intake ducts, drivebelt, engine cooling fan and upper as well as lower radiator hoses. Remove the air conditioning compressor bolts and screw the air conditioning compressor loose from the hoses so the compressor can be tied with rope or wire away from the engine. Proceed by the further removal of the alternator, coolant reservoir, drivebelt tensioner, idler pulleys, the vibration damper, and the power steering pump although the hoses remain connected. Take out the dipstick tube, the 
Oil Pan and the pick up tube; unbend the heater hoses; take off the water pump. Remove timing cover bolts, and then front cover and the oil pump. Reinsert the bolt to crankshaft and rotate the crankshaft until there is the correct alignment of timing marks. Remove the tension of the chain by pulling it back and fixing it by using a drill bit on a piece of metal then you take off the 
Camshaft sprocket bolt and the timing chain with the sprockets attached to it. Check for any signs of wear or faults in the camshaft or crankshaft sprockets and as already indicated if a new timing chain is required, then the entire set should be changed. To install, use a rag placed at the oil pan opening, clean the area and press the tensioner before fixing the camshaft thrust plate in place. Fit the timing chain and sprockets in the order specified in the workshop manual and check that the timing marks are in position, then apply its to the camshaft sprocket bolt thread locking compound and lubricate the timing chain. After taking the drill bit from the tensioner, fit the oil pump and pickup tube and the timing cover and its gasket. Use RTV sealant where ever needed, put the timing cover in place and then the oil pan. Grease the hub of the vibration damper and then place it back into position; proceed in the opposite manner of that which was described above. Last but not the least, pour some coolant and engine oil, start the engine and look for any signs of leakage.
