If you work on getting the timing right for 2014 or older cars, you need years of experience because minor mistakes could hurt your engine badly. First, take off the engine cover and unplug the negative battery cable. Turn the right front wheel's lug nuts loose. Then lift the car, take off the right front wheel, and the moisture shield beneath the drivebelt. Start by removing both oil and coolant from your engine. Then take off the drivebelt and the cover of the air filter. Unplug the ignition coils from the engine, take out the spark plugs, and keep track of where they go for easy reinstalling. Take off the valve cover, turn the crank to get the number 1 piston at highest point, make sure marks on cam phasers line up perfectly, and note location before removing them for reinstallation. Push the tensioner lever up before using a special tool to lock it there. Slide a second locking device between the camshaft phasers, then use this device to hold both phasers in place while you separate them. Take off the bolts holding the camshaft bearing caps, reverse their order when removing them. Then, remove the front cap, pick up the intake camshaft from above, and follow by lifting the exhaust one. Release the end bolt and phaser from the journal of the exhaust camshaft before taking off the lower half of the bearing. Put a label on each lifter so you know which one belongs where, and check the camshaft bearing areas for damage. If necessary, replace the cylinder head. Make sure to change the camshaft when the height of its lobe measures more than 0.005 inch different from the factory specs. Pull the crank handle back and forth twice to turn the crankshaft. Make sure engine starts without a fight. Fit the phasers onto the camshaft grooves, keeping the markings lined up, then put on the bolts. Soak the lifters in clean engine oil, and put them back where they started. Also apply oil to the oil channels as you place it in. Place the
Timing Chain onto the exhaust phaser sprocket, making sure all parts align correctly, then add the exhaust camshaft, followed by the intake camshaft. Put the camshaft bearing caps in their right spots, making sure they go in the right way. Tighten the bolts step by step. After checking engine timing marks fit together, take off the tools, turn engine two full times, then recheck the valve adjustment. Before closing up, apply thread sealant to the timing chain tensioner plug and mount it tightly. Finish reinstalling in the opposite order of removal.
