2. Remove the pump assembly mounting bolts.
3. Separate the pump assembly from water pipe and remove.
4. Clean gasket and O-ring mounting surfaces.
5. Install a new O-ring on water pipe and lubricate with water.
6. Install a new gasket on pump body.
7. Press the water pump assembly into water pipe.
8. Install pump mounting bolts and tighten to 27 Nm (20 ft. lbs.).
9. Install timing belt and cover. Refer to Timing Belt procedures.
10. Install drive belts.
11. Fill the cooling system

1. Disconnect the negative battery cable.
2. Remove the accessory drive belts.
3. Remove the timing belt covers.
4. Identify the timing belt running direction to avoid reversal during installation.
5. Loosen timing belt tensioner bolt and remove timing belt.
6. Remove the crankshaft sprocket flange.

1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
8. Install the crankshaft sprocket flange.
9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
11. Install the timing covers.

This procedure is wayyyy to long to list on here. Your better off going to your local auto parts store and buying a repair manual for your car. It will have both detailed procedures for fixing both of your items. You can also goto the library and get the factory service manual for free. Good luck to you and thanks for using fixya!

The 3.3 and 3.8 use a chain.

Try (repairpal.com) for estimate for your particular area. You may have to enter Grand Caravan to get the 3.8L engine .
I'm thinking 2 hrs.
