1. Clean up any mess that you made and install the new parts. Water pump bolts should be torqued to (15 NM or 11 lb-ft). Timing tensioner assembly bolts should be torqued to (15 NM or 11 lb-ft). Finally, the belt tensioner roller should be hand tightened at this point.
2. Transfer the markings from the old belt to the new one. Install the belt by starting at the crankshaft sprocket, lining up the marks on the belt to the marks on the crankshaft sprocket. Then go to the water pump. Route the other side of the belt around the tensioner roller and finally over the camshaft sprocket.
3. The belt is now installed and all you have left to do is set the proper tension. Make sure the nut circled in red is hand tightened.
4. Use the Tool 3387 (or whatever else you can use to rotate the highlighted metal tab) and rotate it counter clockwise until you can remove the locking plate from the tensioner. Keep the tensioner in that position until you complete the next step.
When you remove the locking plate then rotate the metal tab clockwise until you can fit a 8mm object (a 8mm drill bit works so does a 8mm allen key) between the tensioner lever and tensioner housing. The specifications call for the distance between the two to be between 6mm and 10mm so 8mm is a good middle ground. NOTE: When rotating the metal tab, take care not to bend anything. When you have the proper clearance then tighten the nut on the metal tab to (27NM or 20 lb-ft).
5. Install the lower timing cover and torque to (10NM or 7 lb-ft.). And install crankshaft pulley and tighten those bolts to (10NM or 7 lb-ft.) + 90 degrees.
6. Rotate the engine clockwise a few times and make sure that all of the timing marks line up correctly.
7. Install upper timing cover.
8. Install the plastic hose clips.
9. Install the drive (serpentine) belt tensioner and the actual belt.
10. Return the carrier to the correct position.
11. Reinstall the bumper.
12. The last step is to bleed the coolant. Make sure that your car is level before bleeding. Open up the bleed screw on the coolant line circled in red and start pouring coolant into the coolant reservoir. Tighten the bleed screw when coolant begins flowing out of it. Top off the reservoir and install the cap. Start the engine and run it at 2000rpm for 3 minutes. Then let it idle until engine is at normal operating temp (middle of the temp gauge). Turn off the car and let it cool down. Coolant level will decrease so top it off as necessary.
