The timing system is a bit complicated and one wrong move will result in rather intolerant and downright destructive behavior by the engine. This procedure should only be done by very experienced people and if in any doubt about ability an expert should be consulted. Reverify all jobs in order to be assured of correctness before switch on the engine. Starting with the cable, it is necessary to remove it from the negative terminal of the battery in addition to the lower splash shields. Take the TDC number 1 position for the engine and then disconnect the valve cover and the timing chain cover. Turn the crankshaft slightly anti-clockwise to compress the chain tensioner, insert a 0.040 inch pin into the alignment holes and turn the crankshaft slightly clockwise to lock the pin; also ensure the marking on the crankshaft sprocket aligns with the one on the engine block. Check the tensioner rod length; if found to be in excess of 0.571 inch the timing chain should be replaced. Undo the timing chain sprocket mounting bolts as well as the timing chain tensioner; afterwards, also undo the cam chain guide and the camshaft chain tensioner arm; and finally, the timing chain. It will not be safe to rotate the crankshaft or camshaft after the timing chain has been pulled out. Wipe all the parts with solvent and blow with compressed air; visually check the chain tensioner, timing chain guides, timing chain and sprockets for wear or damage and renew them if doubtful. Make sure the timing mark on the crank shaft sprocket is lined up with the 'TDC' mark and the 'UP' mark on the cam shaft sprocket is on top of the cylinder head with index marks on it at the top edge. Slide the timing chain over the crank sprocket positioning the plated link over the dot on the sprocket, place the timing chain over the camshaft sprocket positioning the chain dot on a coloured chain link. Dex: camshaft timing chain guide and tensioner arm, the bolts to the specified torque and the timing chain tensioner. Pull the pin out in the tensioner at this time and make sure that the mark on the sprocket is facing up at 12 o'clock position, and the other two lines on camshaft sprocket atop the cylinder head. With the slow speed rotate the crankshaft at least two revolutions towards clockwise and realign the timing marks along with the index marks of the camshaft sprocket. If the crankshaft binds, do not force it because that will only be an indication of improper valve timing; take off the chain and then reinstall it. Last, fit valve cover and timing chain cover, while other procedures are the inverse of the removal procedure reinstall the battery, start and check for any signs of leakage.

To have access to the components one has to disconnect the cable on the negative terminal of the battery. Position the engine at Top Dead Centre for the number 1 cylinder, and then remove the valve cover along with the engine front cover. A small amount of rotation clockwise should be made in the crankshaft in order to screw into the holes a 0.05 inch (1.2 mm) pin and this will compress the chain tensioner, the other way round should be made in order to fix the pin. Then, dismantle all the bolts from the mounting and extract the timing chain tensioner and the upper timing chain guide between the camshaft sprockets and remove the camshaft timing chain guide, the tensioner arm, and the timing chain. For test or assembly, clean all parts by solvent and blow with compressed air free from oil, lubrication and dirt, then examine and check the chain tensioner for wear or damage and drain off any oil if refilling later. Inspect the timing chain guides, timing chain, and crankshaft and camshaft sprockets and replace any item that is suspect in its ability to provide long and worry-free service. During installation, if the crankshaft has been turned, be confident that the number one piston situated at the top dead centre with the timing mark situated in line with the pointer on the crankshaft sprocket. Place the chain alignment dots on the camshaft sprockets with the chain as follows; turn the sprockets until the alignment dots likes up. Fit the coloured link to the crank sprocket at full clockwise position and over the exhaust camshaft sprocket and the VTC actuator, such in a way that the dot is on the same colour of the chain link. Place the camshaft timing chain guide and the tensioner arm and tighten the bolts in the already mentioned torque limit;finally fit the timing chain tensioner and the upper timing chain guide and tighten the bolts in the already mentioned torque limit. Take out the pin in the timing chain tensioner, bolt on the valve cover and the engine front cover and rearrange the battery. Last, with the engine on, observe the presence of oil or coolant leaks.

The timing system is complex, and severe engine damage will occur if mistakes are made. Only highly experienced individuals should attempt this procedure, and if there is any uncertainty about abilities, consulting an expert is advised.

The timing system is complex, and severe engine damage can occur if mistakes are made. It is advised not to attempt this procedure unless highly experienced with this type of repair. If unsure, one should consult an expert.

If the crankshaft binds or seems to hit something, do not force it, as this may indicate incorrect valve timing. In such a case, remove the chain and repeat the installation procedure.

Ensure the number one piston is at the top of its stroke with the timing mark aligned with the pointer on the crankshaft sprocket.
