At least, to perform these operations, particular tools such as camshaft position tool (303-1552), timing of VCT locking tool (303-1097), crankshaft pulley alignment tool (303-1550), the flywheel locking tools (303-393A and 303-393-02) and timing pin (303-748) are needed. The following are the tools you should have before commencing the job. This is in contrast to the other three types in which only clockwise rotation of the crankshaft is allowed. First, get rid of the negative terminal of the battery, then free the right-side lug nuts of the wheel, lift the car and then, finally, remove the wheel. Next, pop the right-side inner fender splash shield and under-vehicle splash shield, add the engine cover, CAC inlet and outlet tubes and bracket if any. Remove the connectors for the powertrain control module and main engine harness, and the coolant expansion tank, air filler housing inlet and outlet hoses, turbocharger inlet hose, and unbolt the water pump pulley. Take off the drive belt, the right-side drive axle, the intermediate shaft bearing support bracket, the starter motor and the alternator. Place a jack underneath the engine oil pan so the right-side mount weight is relieved, then remove the right-side engine mount. Here, now that the mount has been taken off, lift the engine slightly and take the drive belt tensioner off also. Pull out the vacuum line retainer bracket on rear side of cylinder head and then turn counter clockwise and take away the cover stud bolt. Pull the side inspection cover to the side to unlock the clip, retract the cover and take off the side timing cover. The water pump pulley mounting bolts and pulley have to be removed next; in addition, the timing cover fasteners and harness fasteners have to be unbolted from the cover. Pull the top part of the cover downwards and remove it in the forward and backward direction parallel to the engine. Take off the valve cover and the bracket of the right side engine mount. You can now then place an engine support fixture and make sure that it is well fastened on the cylinder head. Turn the crankshaft further until the camshaft phaser marks are in line with the '11 o'clock' mark and then, unscrew the TDC timing hole plug and install the timing pin in it. Turn the crankshaft clockwise slowly until you can feel the crankshaft balance weight hitting the timing pin thus showing you that the engine is at TDC. This should be done with considerable care and the locks that are used to hold the flywheel in place must be firmly fixed into position. Locate the crankshaft pulley bolt and pulley and then, loosen it and then turned it until the VCT sprocket timing marks are at 12 o'clock. Place the VCT locking tool over the two camshafts so that it grips the VCT sprocket in both cases. Turn anti-clockwise until the tab fits into the tensioner body then tighten using a drill bit or Allen key. Examine the timing belt on the engine and if you see any trace of wear replace it. Place it over the crankshaft sprocket first before the intake and exhaust camshaft sprockets and over the tensioner. Take out the drill bit or Allen key from the tensioner so that the latter can stretch and retract to eliminate slack. Put the crankshaft pulley alignment tool where the CKP sensor was located and fit the crankshaft pulley and bolt. Revolve the positioner-counter to make it '0' before removing the alignment tool and tightening the crankshaft bolt. Pull out the VCT locking tool, the flywheel locking tools and the timing pin from the cylinder block. Slowly rotate the crankshaft 45 degrees clockwise in a locking position 1-3/4 turns and align the timing pin available on it, rotate it further till the crankshaft balance weight touches the pin. Align the VCT sprocket timing marks to the 12 o'clock position and fit the locking tool of the VCT. If the tool can be installed, the timing belt is correctly installed If the timing belt cannot be installed the above diagram shows that it is inserted incorrectly. Replacement of the crankshaft position sensor, the engine mount bracket nuts and bolts then tightening of the screws. Last but not the least, pick up the timing cover and fasten the screws to complete the repair sequence in a backward way of the same processes.

Timing system is delicate, and if the wrong thing is done, serious damages can be done to the engine and therefore, should be handled by experts only. First, unplug any of the wires with a negative connection and then, take off the air intake duct and the spark plugs. Remove the accelerator and the cruise control linkages from the throttle valve, together with the catalytic converter monitor and the heated oxygen sensor connections. Next, unbolt the wiring harness support and place the wiring harness to the side, and take off the valve cover, and drain the coolant collecting it in a container and placing the coolant pipe to the side. Open the passengers door on the timing belt side and loosen the right front wheel lug nuts unlatch the hood and raise the car remove the front wheel and the fender splash shield. Insert the crankshaft in such a manner that the timing pin is not used to lock the crankshaft and position the engine at TDC for number 1. Of the water pump pulley bolts, crankshaft pulley, as well as the lower timing belt cover need to be removed. S ecure an engine hoist / engine support fixture to the engine, then, remove the upper engine mount and studs from the engine mount bracket. Remove the electrical connector from the knock sensor, take off the upper timing belt housing, also unbolt and extract the accessory drive belt idler and the engine mount bracket. It will be necessary to use the manufacturer service tool to adjust the camshafts to the TDC position, and, if the timing belt is used again, it is necessary to mark at which direction it was removed. Tighten the tensioner until it locks in place and then remove the timing belt while at the same time preventing the sprockets from rotating. If in doubt the old belt should be inspected for wear or damage and oil or coolant leaks, the belt should be replaced. The belt tensioner and sprockets should also be checked for wear if any, or if it could be replaced with another new one. Before starter the engine turn the crankshaft with your hand, at least two revolutions, and be sure that the engine still in the TDC, on the cylinder Number 1. Fix the TDC position of the camshafts by loosening the camshaft sprocket bolts and using holding tool so that these will not rotate. Reinstall the timing belt and make certain it turns in the reverse of the original direction with all the looseness on the tensioner side. After proper installation of the belt it can be attached to the timing belt inner shield and tightened to the correct torque. If your camshaft has sprocket bolts, you should tight these bolts while holding the sprockets in position, then remove the aligning tool and timing pin. The vehicle's crankshaft should be turned through 720 degrees to allow the timing belt to set, with the timing pin able to be inserted fully. If necessary you can never use the holding tool to realign any of the camshafts that seem to be out of alignment. The procedure of reassembly is similar to the removal process to guarantee that all the fasteners have been tightened to the correct torque. The Powertrain Control Module therefore requires a self- learning of the idle and fuel trim for it to perform efficiently after reconnecting the battery.
