Pull the clamp off the negative terminal of the battery, and drain the coolant. Lift the front-end of the vehicle off the ground by using jack and support the car by using jackstands, and then dispose of the engine oil of the car. The drive belt and the tensioner must be taken out, together with the oil pan and the oil pump pick-up tube. Next remove the alternator bolts and set the alternator aside and unbolt the air conditioning compressor from its mounting location and move it to the fender using ties to clear the area of the work. Crankshaft pulley, the radiator lower hose, the heater hose from the timing chain cover housing or the water pump inlet for the oil cooler based models should be taken off. Extract the camshaft sensor of the timing chain cover and then, remove the water pump. Sling off the power steering pump and place aside, then remove the timing chain cover-to-engine block bolts. Approximately screw the crankshaft pulley bolt and then rotate the crankshaft until the timing marks on the crankshaft and camshaft sprockets coincide with each other with the arrow of crank shaft pointing upwards and arrow of the cam shaft sprocket downwards. Loosen the camshaft sprocket bolt without rotating the camshaft and using two large screwdrivers, carefully push the sprocket forwards. Perfect sets of timing chains and sprockets should be interchanged; when fitting a new timing chain, remove the crankshaft sprocket with a puller, and fit a new one to mesh with the key in the crankshaft and the keyway in the sprocket. Check the timing chain using a magnifying glass to find out if the timing chain dampener is worn out or cracked, if so replace. Remove the timing chain and sprockets and wash them with solvent and dry them with compressed air, check for wear and damages; if afraid damage or excessive free play replace the timing chain and sprocket. You may require a gasket scraper to avail the old gasket material and sealant from the cover and engine block but be careful so that you do not harm the aluminum cover. Wipe the gasket sealing surfaces with lacquer thinner or acetone and align the dowel pin of the camshaft at the down motion. Mesh the timing chain with the camshaft sprocket and then mesh the crankshaft sprocket with the timing chain to align to the timing marks. Should the crankshaft have been advanced, rotate it till the arrow is pointing upwards on the crankshaft sprocket, and were the camshaft advanced, place the sprocket loosely then adjust till the markings match. Fit in the camshaft sprocket bolt and tighten to the recommended torque value, with the camshaft sprocket splined-ID, lubricate the chain and sprocket with fresh engine oil, and apply a new gasket on the cover to stick to it until the gasket lays flat on it. Fit the cover to the engine block in such a manner that the oil pump gear flats will fit over the crankshaft flats, torque the bolts to the prescribed standard in a zigzag manner. Other components are reinstalled in the reverse order to how they were removed. Last of all, pour in the oil and the coolant as well start the engine and visually ensure that there is no leakage.
