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.

It is very intricate and any mistakes could lead to serious damage to the engine. You should only try it if you are extremely experienced or consult a professional. Take out the timing cover, air intake resonator, brake vacuum pump, drive belt, thermostat housing, radiator hoses, heater hose, alternator crankshaft pulley upper intake manifold and valve covers. Take care not to spoil the magnetic timing wheels on camshafts. Remove both up and down oil pans. If necessary take off the timing cover and coolant outlet housing. Temporarily set up the crankshaft pulley bolt then bring together the timing marks on both crankshaft and camshaft sprockets. Check that the phaser marks are in line with plated links. Indicate direction of rotation for all chains. Press tensioner plungers then detach timing gear splash shield. Unbolt oil pump tensioner and sprocket. Put camshaft phaser lock tool between the phasers and loosen oil control valves. Remove phasers as well as timing chains. Inspect parts for wear or damage. Replace if need be. Tidy up units then fit new chains. Rotate crankshaft verifying alignment of marks. Install before doing this coolant housing together with water pump gaskets. Apply RTV sealant so as to have a proper installation of your Timing Cover. Tighten bolts on cover before finishing other installation steps. Fill engine with coolant or oil; start vehicle for leak testing.

The remainder of the installation is the reverse of removal. Add coolant and engine oil, then run the engine and check for leaks.

Reinstall the bolt into the crankshaft and turn it until the timing marks are in the correct position.

The remainder of the installation is the reverse of removal. Add coolant and engine oil, then run the engine and check for leaks.

Care should be taken not to damage the magnetic timing wheels on the camshafts.
