Removal
CAUTION: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The
crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted
together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you
loosen the pulley bolt. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in
place by the special service tools, otherwise severe engine damage can occur.
CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning
gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Loosen the 3 coolant pump pulley bolts.
3. Remove the accessory drive belt and idler pulley.
4. Remove the crankshaft pulley.
5. If equipped, remove the 7 screws and the underbody cover.
