I am in the process of changing the water pump on this car however I may have done a bad thing. In order to access the water pump I had to remove a sprocket that the timing belt was going around. When I was loosening the bolt to remove it, the sprocket slipped on the belt.
Now my question is that I am wondering if that large sprocket is just a thing to let the belt run on or if it drives something inside and therefore I will need to redo the timing. I don't think I have lost the timing between the main shaft of the engine and the upper cam, just this sprocket I am worried about. I cannot think of what inside it would be driving, or do these engines have overhead intake valves and traditional exhaust cam? (or vice versa)
Thanks so much
Joel
