If you have an original equipment radio with anti-theft protection, make sure to write down the code before disconnecting the battery. After installation, you will need this code to restore radio operation. It is recommended to clean the valve cover, as well as the area surrounding the valve cover, to avoid getting dirt or debris into the engine. Disconnect the negative cable from the battery. 2. Disconnect the PCV hose and ground wire from the valve cover. Using a 10mm socket, remove the four cap nuts holding the spark plug wire cover. Remove the spark plug wire cover and remove the spark plug wire boots from the spark plugs. Using a 5/8″ spark plug socket, remove the spark plugs. This will make turning the engine over in step 5 easier. Using a 10mm socket, remove the remaining eight nuts and washers holding the valve cover, and carefully lift off the valve cover. (Note: Inspect the valve cover gasket and rubber seals surrounding the spark plug holes. If they are in good condition, they may be re-used). Set the cover, gasket, and seals aside. 3. Loosen and remove the three distributor mounting bolts using a 12mm socket. Remove the distributor from the cylinder head and rest it carefully next to the head, you do not need to unplug the distributor from the wiring harness. Be careful not to lose the o-ring seal. Inspect the seal for damage. If it is in good condition, it may be re-used. 4. Remove the two bolts holding the middle timing belt cover using a 10mm socket. Remove the middle timing cover and set aside. 5. Turn the steering wheel so the front tires are pointing to the left. Now you can access the crankshaft pulley bolt through the fender liner. Rotate the engine counterclockwise using a 19mm socket until the no. 1 cylinder is at top dead center (TDC) on the compression cycle. The no. 1 cylinder is at TDC when the white TDC mark on the crankshaft pulley is aligned with the pointer on the lower timing belt cover. 6. Using a 14mm socket, loosen the camshaft sprocket bolts approximately 1/2 turn. Do not remove the bolts.
