Disconnect negative battery cable. Remove serpentine belt, brackets and shields necessary to access crankshaft pulley. Remove timing belt front cover.

Remove crankshaft pulley. Align timing marks on sprockets with marks on rear cover. Loosen water pump bolts. Using Timing Belt Adjuster (J-33039-A), rotate water pump to release timing belt tension. Remove timing belt.
If camshaft sprocket requires removal, remove camshaft carrier cover. Hold camshaft using open-end wrench. Remove sprocket bolt, washer and sprocket.
If crankshaft sprocket requires removal, remove sprocket bolt, washer and sprocket. Remove Woodruff key and washer (if required).
If removing timing belt rear cover, remove timing belt tensioner, rear cover bolts and cover.

Remove lower radiator hose from water pump. Remove water pump bolts, water pump and seal ring.
To install, reverse removal procedure using new seal ring. Tighten fasteners to specification

Nicely copied from chiltons! Question. Whats the J33039-A look like? Is a sort of spanner wrench? The J33039 is pictured but not for my 94 2.0 eng. The J33039 is a crows foot but my waterpump has no flats just two odd looking holes close together.
