With the tension on the timing belt relieved, the belt should slide easily off the sprockets. Timing belts that have been used for a long time may stick in the pulley grooves and require some gentle prying with a screwdriver to release. Inspect the timing belt pulleys and water pump for any need to replace before proceeding to install the new belt. Torque the timing belt to the proper specifications, paying special attention to "torquing" specs on the engine manual, particularly the crankshaft pulley mounting bolt which usually has a very high torque spec. If equipped with a hydraulic timing belt tensioner, removal may be required to compress the piston back into the cylinder after a ratchet is released. Place into a vise and compress until holes line up to allow the insertion of a holding pin. Once the pin is in place, the tensioner can be re-installed when the belt is installed with the pin pulled to allow the tensioner to place tension onto the timing belt.
