Any advice for removing a waterpump that seems to be locked in?

v6 or v8? v6 should take 2.2 hours, v8 should take only 2 hours to replace waterpump, replace coolant. water pump replacement is not an amateur job, please be careful ....

Just be patient, that's about all the advice I can give. Be patient! and keep working at it.

you need a special tool to remove the pulley. go to the parts store the rent this tool. when you bring it back they give your money back for it

u need a shop manual and special tools n technique--library has chilton books and if u perform chec nearby components like waterpump etc

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.

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.

it should come off turning left, you may need a tool if you dont have a wrench or big channel lock pliers to try.

remove air filter housing,remove secondary air check valve bracket,if equipped,remove lower radiator hose from the thermostat housing,remove waterpump bypass hose, remove waterpump cover,use special tool to remove waterpump,install a new o-ring inwaterpump housing

You need a special water pump tool. you can rent one from Auto Zone. The water pump housing is the bottom radiator hose on the right side of the engine. remove the hose and the outer-caseing, the waterpump is now slightly visable. Use a .5 inch rachet with the Special tool and turn clockwise.

The water pump on your vechile is pretty straight forward, not too complex as alot of cars are, for an overview of the process see the link below.
