I should have added that when following belt replacement procedures, there is a spring-loaded tensioner pulley to take up the slack in the belt. Don't rely on that alone as the spring can become weak or the pivoting bracket can stick. Rotate the crankshaft two revolutions in the normal direction, by hand, so the slack is on the back side of the engine by the tensioner pulley, then use a small pry bar to help the spring pull on the pulley. If the belt is left loose, it is really hard for it to jump a tooth on one of the camshaft sprockets, and it is not possible to jump on the crankshaft sprocket, but it can slip over the water pump pulley and lead to the engine running too hot.
