REMOVAL

1. Install a 1/2 inch drive extension into the belt drive tensioner (6).
2. Push down on the extension to release tension.
3. Remove the drive belt from the power steering pump (13
4. Slowly return the tensioner to the original position.
5. Remove the belt.

INSTALLATION

1. Thread the drive belt through all the pulleys except for the power steering pump (1) and the drive belt tensioner (6).
2. Insert a 1/2 inch drive extension into the drive belt tensioner.
3. Push down on the tensioner and feed the belt around the tensioner wheel.
4. With the tension applied, complete the belt routing. Make sure the belt is properly seated in all pulleys.
5. Slowly return the tensioner back to its original position. This will apply tension to the drive belt.
6. After installation, check the belt for proper seating on the pulleys, proper routing and alignment.
7. Start the engine and check for proper belt and accessory operation.

1. Remove air filter to give you more room to play
2. Loosen alternator and alternator tensioner. Alternator tensioner bolts to water pump so that bolt will need to come out.
3. With the alternator loose, the main drive belt should be loose and be able to be removed, do this.
4. Loosen the tensioner bolt for the air conditioner, on the underside of the engine. Losen the nut on the air conditioner tension wheel. The tensioner wheel should now slide up and down freely, allowing removal of the air conditioner belt.
5. Remove the 4 x 10mm bolts on the water pump pulley. Remove the water pump pulley.
   
6. Remove the 4 x 10mm bolts on the camshaft pulley. This is the main pulley that all the belts connect to. There is a large 17mm bolt in the middle of this pulley that does not need to be removed. (Crankshaft Bolt).
7. The camshaft pulley should slide off, however you will probably have no clearance (because of the crankshaft bolt) to remove the pulley. The pulley has to be removed.
   
8. Place a jack under the sump, use a piece of wood to protect the sump. Jack the sump up 1/2 inch. Undo the two 14mm bolts in the engine mounts. When the two left hand engine mount bolts are out, lower the jack slowly until you can slide the camshaft pulley out.
   
9. Remove the plastic timing belt cover.
10. You should now see the timing belt, remove the timing belt tensioner pulley, being careful not to move the timing belt wheels.
11. Undo the bolts holding the water pump.
12. Water pump should come off, water will come out if you haven't drained it.
13. Scrape off gasket.
14. Install new water pump.
15. Reassemble in reverse order.

4. Slacken tensioner pulley bolt [9]. Push tensioner pulley against belt.
5. Ensure belt is taut between injection pump sprocket and tensioner pulley as well as crankshaft sprocket and camshaft sprocket.
6. Position tensioner lever [8] against tensioner pulley housing.
7. Remove locking bolts from sprockets [4] & [5].
8. Apply a load of 10 ... 12 kg to tensioner lever. Use spring balance [11].
9. Tighten tensioner pulley bolt to 80 Nm.
10. Turn crankshaft slowly 45 degrees anti-clockwise. Use spring balance to tension belt.
11. Repeat tensioning procedure at 45 degrees intervals for one anti-clockwise turn of the crankshaft.

NOTE: DO NOT turn crankshaft clockwise during tensioning procedure!

12. Fit tensioner lever to original position. Tighten nuts [12].
13. Install: Injection Pump flange [6], Camshaft sprocket flange [7], and water pump pulley.
14. Install components in reverse order of removal & refill coolant.


PLEASE DO RATE MY RESPONSE. THANKS!

The oil pressure sending unit is behind the front engine mount. You will need a deep special oil pressure socket to remove and install.It is NOT an easy task. There is no short cut but you might find it easier to remove the oil filter adapter, if you do that you should replace the "O" rings on the adapter. The oil pressure sender is mounted on the filter adapter

Hope this helps (remember comment and rated this).

First of all,you will need the Northstar waterpump removal tool, You can get this from most reputable auto part stores and looks like this :-



The following link shows a selection of different manufacturers.


http://www.bizrate.com/automotive-repair-tools/northstar-water-pump/

You need to remove the air filter housing and ducting to gain easy access to the pump.

Remove the shield covering the pulley and belt. The belt is easily removed by levering the tensioner pulley.

The water pump is located at the lower radiator hose manifold where you will also find the thermostat.Remove the manifold cover and you will see the water pump.

Insert the removal tool over the pump making sure it is locked in position.You will need to use a breaker bar on the removal tool and turn the tool CLOCKWISE to release the pump (1/4 turn), or if you imagine the breaker bar being vertical, push towards the windscreen of your car,it takes quite a bit of force to unseat the pump hence the use of a breaker bar.

As for the waterpump itself, DO NOT buy anything other than AC DELCO as they are the highest quality and is a genuine GM replacement part.

Water pump part number AC Delco 252707

Installing the new pump does not require as much torque as removing the old one.
Tighten the new pump to 73 ft.lbs. making sure it is seated properly before tightening.

Don't forget to clean out the water pump housing prior to installing the new pump and don't forget to include a new water pump gasket and housing cover gasket.

It is also a good idea to install a new thermostat while you're at it.

Regards.
