Just replaced the water pump - 96 xj. Everything works well but the belt going over the fan pulley moves side to side about 1/16th of an inch, so it it noticeable.

1. I had the fan/clutch unit upright for two days but it got knocked over and was horizontal for about 4 hours.

2. I had a difficult time re-tightening the bolts to the fan. But they are tight enough that a right belt slips when trying to tighten them more.

What would you recommend troubleshooting or suspected problems?

For future reference what is the best way to re-tighten those fan bolts. (I have searched and have not found a good reference.)

Thanks ahead of time.
