I need help, my water pump was going so I started to tear into it. got the front part of the engine off, now it looks like I need to take off the top half too... can any one offer some help. do I need to remove the valve covers to loosen up the chain so i can change the water pump? The last car I worked on was a 78 thunderbird. This engine is in a shoe box compared to that .. don't get me worng I love my car alot but.... the book i have is rather confusing to me.
