The serpent belt is a challenge and firstly take a few pictures of the routing to reference when fitting. Use a 12" adjustable spanner to relax the tensioner, it fits nicely on the tensioner and gives good leverage. Lever the tensioner and slip the belt off the pulley, then ease the belt off and out from the motor.
Use this opportunity to give the front of the engine a degrease.
Fitting the new belt can be made far easier by using a bungee cord to pre-tension the belt prior to placing around the tensioner pulley. Loop the belt over the crank pulley first followed by the rest of the pulleys excluding the tensioner. Position the belt loosely around them and lastly (the important bit) hook the bungee cord onto the belt near the tension pulley and attach the other end remotely to apply tension. 
Now examine each pulley to check the belt is seated correctly, the slight pre-tension will prevent the belt from slipping off other pulleys should you need to reposition the belt.
Once seated then use the adjustable to lever the tensioner pulley and slip the belt on... et voila!

thanks for that justbadly, next question is what is the best method of bleeding the brakes pressure or vacuum
