Notice: Refer to Fastener Notice in Service Precautions.

1. Install the water pump bolts.

• Tighten the bolts to 10 Nm (89 inch lbs.) .

1. Install the water pump pulley and bolt until snug.
2. Install the drive belt
3. Install the water pump pulley bolts.

The nodule is in the distrubutor and a rebuilt distrubutor has a good module in it and they can be bought for exchange at most auto parts stores for less than $200 The module is a little cheaper but it's diffacult to install as the distubutor has to be fully disassembled to install it and othe parts can be bad too and chaging the whole unit is a plug and play action. Just check that the unit is powered up with the key and it is and it turns while cranking ( the timing belt could be broken ) If it turns and has power change it and drive away.

it could be the injector pump we work on them alot its under the manafold its a fairly diffacult task do change email me if u wanna to get help [email protected]

Apply a sealer (GM P/N 12346004) to the bolt threads.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

I've never seen a pulley fail... If it's just the pulley, remove the fan and change pulley. If pump has failed and the pulley is wobbling, yes...change the pump. To remove, just take off what's in the way, take the pump off, remove ALL gasket material on the block and put new pump on, reversing the process. There are lots of half decent manuals to guide you if you need them but if you pay attention to what goes where and mark everything as you go, you should be OK. If you overheated, change the thermostat also...they often fail after an overheat!

Here are the steps required to change the water pump on the 3.0L engine.

1. Disconnect the negative battery cable.
2. Drain the cooling system.
3. Remove the drive belts. Remove the timing belt covers and the timing belt.
4. Remove the water pump mounting bolts.
5. Separate the water pump from the water inlet pipe and remove the water pump.
6. Inspect the water pump and replace as necessary.

To install:

1. Clean all gasket and O-ring surfaces on the water pump and water pipe inlet tube.
2. Wet a new O-ring with water and install it on the water inlet pipe.
3. Install a new gasket on the water pump.

1. Install the pump inlet opening over the water pipe and press until the pipe is completely inserted into the pump housing.
2. Install the water pump-to-block mounting bolts and tighten to 20 ft. lbs. (27 Nm).
3. Install the timing belt and timing belt covers. Install and adjust the drive belts.
4. Reconnect the negative battery cable. Fill the cooling system to the proper level with a 50/50 mixture of clean, ethylene glycol antifreeze and water.
5. Run the engine and check for leaks. Top off the coolant level, if necessary.

Your best bet here is to go to your local auto parts store and ask for a Haynes Manual for your vehicle. They run about 15 Bucks and will give you all the details on how to change your water pump. The water pump is kinda a pain to change on most vehicles but can be done in a good 8 hours. Thanks for using fixya! Hope this gives you some direction.
