Timing Belt Tension Adjust

Hello,
I bought a 1995 civic and the engine whines. The whine is realted to the RPMs. When I bought it they said they just had a new tmining belt installed. I suspect that I need to ajdust the tension on the belt and the whine will go away.
So how do I know how tight to get the tensioner? Also can I adjust the tension without taking off the crankshaft pulley (and all the other stuff attached)?
Thanks,
G
