First of all,you need the removal tool which looks like this.

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.

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.

Just as an aside, the Northstar is a 4.6 , not 4.8.

SOURCE: need to replace the alternator on my 1998 aurora

Hey man, it's not too bad. Discharge the A/C. Take out compressor, take out bracket, take out alternator. There will be 2 bolts on the top of the alternator which are kinda hard to get to. Then there are two bolts on the in side of the compressor and I believe 4 total on the front. Google an electric motor repair place in your area!!! I get mine rebuilt for $50 vs $300 form a parts store. Or, get a brush kit. I believe on those you don't even have to take the alternator apart, only the black cover on the back. There you go, $12 you did it yourself.

SOURCE: Hi, please can you tell

If I remember correctly it has somefhing to do with capacity. The best way to find out is check with a GM dealer to see if the part number for a 1993 is the same as a 1998

Northstar engine? They are on the drivers side. Back of the engine. You see a belt that drives them. Replace the belt also. Remove the belt tensioner.

The water pump on the Northstar is inside a housing, and I believe it's on the drivers side. You'll also need a special tool to remove it, you can buy one at the auto parts for about $30 give or take.

Can't find smog pump for 99 gmc jimmy sle, help dealer keeps ordering secondary air pump. the smog pump is grey not black.

The secondary Air pump is the smog pump. It's located underneath the radiator support on the passenger side behind the oil filter access cover. and has an extra piece attached to it for air flow from the intake to the output. once you get the bracket out take it apart and you'll see they are the same

Intake manifold contains what I believe is a spring loaded valve meant to relieve excess pressure. (located right side end of intake). This valve opens constantly resulting in a vaccum leak and a rough...

The vacuum diagram below may help you identify the part, you can also use the link below to view more information and see a larger version of the diagram image. I doubt that removing the cover has any effect on engine performance. There are several vacuum system valves on your engine so it would be difficult to give advice without knowing which specific valve you are referring to. Hope this helps.
