11. Set cylinder 1 to TDC by rotating the crankshaft clockwise until the mark on the pulley lines up with the mark on the timing cover. NOTE: the timing cover mark is hard to see.
With the crank pulley lined up properly your camshaft sprocket mark should be lined as well. With some nail polish or touch up paint, put markings on the belt at the camshaft and at the crank. Also be sure to mark the actual camshaft sprocket and crankshaft sprocket.
12. With everything lined up you can now remove the crankshaft pulley. It is held in place by four 6mm allen bolts. Use a wrench to counter holdthe crankshaft in place while you remove the pulley bolts. When you remove all the bolts you will have to use a flat head screw driver and slowly pry the pulley out. Make sure that the crankshaft does not move when you do this. Just a FYI, the pulley has a notch and can only be installed one way.
13. With the pulley out of the way, remove the lower timing cover. It is held in place by 10mm bolts.
You should now be left with the following:
14. To remove the timing belt you will have to release the tension first . Insert an allen key into the highlighted part and rotate the tensioner roller counter clockwise until you can insert a lock plate inside the tensioner assembly.
Then use the Tool 3387 to rotate the metal tab (highlighted) clockwise. There should now be plenty of slack in the timing belt so you can remove it. Make sure that when you remove the belt that the camshaft sprocket does not move.
15. With the belt out of the way, remove the nut on the tensioner roller and take it out.
16. The tensioner assembly is secured by two bolts. In this picture you can see that I did not use a lock plate since I will be replacing the tensioner anyway.
Here are the new parts - new tensioner roller and tensioner assembly with locking plate installed.
17. If you are planning on changing the water-pump you will have to drain the coolant. Best place to start is by removing the coolant temp sensor that is on the bottom of the radiator (driver side). Make sure you remove the cap on the coolant reservoir. There is a clip that you have to slide out before you can remove the sensor. Have a bucket ready because coolant will be gushing out when you remove the sensor. Although not mandatory, to drain the remaining coolant you can take off the coolant hose from the oil cooler and drain from there.
18. There are three bolts that secure the water pump. Remove those and slide the pump out.
