Water pump removal on 85 cadillac sedan Deville


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. Remove all the hoses from the pump housing, Get it out of the way. Takes a special tool to remove the pump. Rent or buy it. When replacing the pump, use grease to hold the pump seal in place, be careful when putting the pump in, dislodge the seal, do it over. replace the seal.

How to change a water pump belt on 2000 cadillac deville northstar


It has been a while since I have done one, but I do remember that the waterpump and the drive belt are on the right front of the engine if you are standing in front of the car with the hood open. It is a small drive belt and there is a belt guard that has to be removed, then there is a belt tensioner.

How to change water pump belt on a 2000 Cadillac northstar deville


Best way is to remove the water pump belt tensioner. to get the old belt off and the new belt on. this is the easiest way to accomplish the task. 2 bolts hold it in place on the water pump housing.

WHAT TYPE OF WATER PUMP WILL I NEED FOR A 1997 CADILLAC SEDAN DEVILLE V8 ENGINE


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 :-

368f16f.gif

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.

Where is the water pump


If it's the Northstar motor the water pump is located on the driver side of the engine, driven by a small belt. You will not find it driven by the main serpentine belt.

Problem with overheating on 1996 Cadillac Deville with Northstar engine. The information screen read "engine overheating", "idle engine" and "change oil" all within one minute. Are these issues related...


The oil life resets to zero after the engine overheats. Check for external leaks first, make sure the water pump belt is still there and turning. The most likely cause if the car has over 70,000 miles is head gaskets.

98 deville runs hot. i have already changed thermostat


You likely don't want to hear this but Northstar engine a common for head gasket failures. One good test that I use it to fill the coolant tank all the way to the top. Then start it up. If the coolant shoots out of the tank. The heads have a problem.

Water Pump


If you have the NorthStar 4.6L engine this is going to be the easiest water pump you ever done and even if you have not. Auto Zone will be able to help they have a special tool for removing and replacing it. I would suggest replacing the hoses when you do this also. When you get the pump you will also need a O ring for the pump cover, and a new thermostat. get the proper antifreeze also.
Auto Zone should also have some instructions with pic's to help you.. email me if you have any questions.......
