How do you reset the timing on a 94 subaru legacy after changing the water pump?

To reset the timing on a 1994 Subaru Legacy after changing the water pump, first, ensure that the engine is at TDC (top dead center) on the compression stroke for the number one cylinder. Remove the timing belt covers and verify the alignment of the timing marks on the camshaft and crankshaft pulleys with the corresponding marks on the engine. If necessary, adjust the timing belt to align these marks, and then reassemble the covers. Finally, check the tension on the timing belt before starting the engine.
