you need to have a pulley puller to get the pulley off if you don't have one most auto zone part stores have a loan a tool program and they can help you with that on most powersteering pumps the high pressure line will be a fitting or bolt on and the return line is usually just a squeeze clamp hope this helps good luck

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

http://www.etoolcart.com/gmnorthstarwaterpumpsocketast7880.aspx


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.

I do not mean to be hurtful and it will take some time to do. Maybe all day if you have no experience. If you need instructions just maybe you should have some do it for you.

I'd have to see the car to say for sure.
Usually when a belt melts one of the pulleys locked up which would not have been the crank pulley.
A mechanic would check each pulley for movement.
