Do i need to loosen the belt anywhere else or just at the water pump pulley?
Expert:  Ivan replied 7 years ago.

There is one belt tensioner that is spring loaded, and you will need to slacken. Slip the belt off of the waterpump and you can leave the belt in place everywhere else. Just move it so it doesn't get coolant on it. Make sure the car has a belt routing diagram on it. If not draw one so you don't run into any unexpected issues when reinstalling the belt.
