9000 Water Pump Replacement
Step 1

When buying a new water pump, be sure it either includes the 3 O-rings or make sure you buy these separately. If you reuse the old ones, your new water pump will probably leak!

If the coolant hoses have not been replaced in a long time, this would be a good time to purchase all of the replacement hoses and avoid any blow outs down the road!

The first thing to do is to remove the fender liner and serpentine belt.

The pump is located right below A/C compressor. Most of the work is done under the hood rather than in the fender, but you do need to get underneath the car to disconnect some stuff. To get access, you will need to remove the lower plastic panels covering the center of the engine. This is done by removing all of the 10mm bolts.

Now drain the coolant. The easiest way to do this is to just undue the two hoses and catch the coolant under the car.

 

Now remove the coolant reservoir. This is extremely easy, just slide the reservoir out from it's bracket and pull it out.

Next, unbolt the A/C compressor and move it to the space of the coolant reservoir. Remove the bracket that holds the A/C compressor on.

 

 

Now remove the water pump pulley. There are 4-10mm bolts that need to be removed. This can be tricky, as you need to somehow keep the pulley from turning while unbolting the bolts. I ended up using a crowbar and jammed it the back of the pulley.

 

Now for the hard part. You need to remove the coolant pipe that goes from the pump to the turbo.

The bolt on the turbo is very hard to get to. I ended up removing the oil filter to give me the space I needed. I then used a flexible socket to get the angle required. The second bolt on the turbo is easily removed with a spanner wrench.

 

The only thing left is to unbolt the water pump and pull it out. There are 3 bolts that hold it on.

Once it's out on the table, it's beer break time!

Step 2

Now you need to separate the water pump. This is done by removing the bolts and then pulling apart the two pieces.

 

Clean up the surfaces with a razor blade and a wire brush and install the new waterpump with the new gasket. I used a little bit of silicon to make sure it wouldn't leak.

Almost done!

Now replace the O-Rings. The smallest O-ring goes to the small tube on the left. The next smallest O-ring goes on the block connector that goes into the water pump. The largest O-ring goes on the side that goes into the block.

I had trouble getting the block connector removed from the block and as a result, I only replaced the one side.

Once this is done put some Vaseline or soapy water on the o-rings. This will help you slide the water pump back into place.

To get things running again, everything is done in reverse order.

Before putting the plastic engine cover back on, run the car and check for leaks. Also let the car run for awhile to make sure the thermostat and fans are working properly. If the temp goes 3/4 high, then you may want to consider replacing the thermostat and the fan thermo sensor.

If everything looks good, the only thing left is to reinstall the fender liner and the plastic under the car.
