Hello bugzdagr8: My name is Roger and I will answer your question. Yes you do need a special tool to remove the water pump. The GM tool number is J38816-1A. You should be able to get one from a tool dealer. Snap-on ,Mac or Matco sales them. Most parts stores sell them also. The water pump has a lock plate that must be turned. Please rate the quality of your answer. This is how we know you received the correct answer.Should you need more help please just ask. Thank You for using FixYa. Roger

How do I replace the water pump on my Cadillac Deville?


Hi.

Here the instructions.

  • Take off the plastic cover located near the top of the radiator if present.
  • Remove the protective shield located on top of the belt pulling the water pump. You will need to undo two 10mm nuts and one 10mm bolt.
  • Undo the 10mm nut that holds water pump housing togeter with the oil dipstick.
  • Take off the air intake assembly.
  • Move the PCM computer to one side, ensure that the module is safely placed.
  • Release the belt tensioner using a big flat screwdriver.
  • Remove the serpentine belt from the water pump pulley
  • Remove the upper radiator hose. This is held by a metal clamp. Use plyers to remove the clamp.
  • Remove also the clamp from the thermostat housing bypass hose, without removing the hose (you have to bleed coolant first).
  • Unscrew the four 10mm bolts that hold the water pump housing and letcoolant drain from water pump plug. At this point you can also removethe lower radiator hose to drain faster.
  • After coolant drains remove the water pump housing.
  • At this point you have to use a special Water Pump removal tool onwater pump cand turn clockwise until the pump is sliding off thehousing.
  • Remove the pump and the o-ring located inside the water pump housing.
  • Clean and grease the area, put a new o-ring and install back water pump housing
  • Install the new water pump using the special tool and following operations in reverse order.

You may need to use sealant tabs from a Cadillac or GM dealer. Here is what you need.
Better going to your local dealer to get the best product for yourCadillac. You will also need a 3/8'' ratchet, socket and extensions

Youmay also need to replace the housing cover gasket. You will need toreplace the O-Ring, that usually comes with the new pump.
When installing new pump you must also ensure that the new pump is aligned correctly,one of the tabs on the pump housing is different and will lock up the pump, so it must bealigned properly while installing.

Where is the water pump located?


Here is the complete procedure to replace the pump on your 99 Deville.
You will need to purchase the special water pump removal/installation tool.
1. Drain the cooling system.
2. Remove both radiator hoses
The water pump is on the right hand side of the engine and is driven by a pulley that comes off of one of the overhead cams.
3. remove the air cleaner assembly.
4. remove the pulley guard.
5. loosen the tensioner and take the belt off of the pulley.
If you decide to replace the belt you need to remove the tensioner, remove the studs that the pulley guard came off of and the tensioner will come out.
6. remove the water pump housing cover. the thermostat housing is bolted to this cover. it has (4)10mm bolts that hold it on.
7. using the special tool, turn the water pump clockwise (it twist-locks into the housing) and remove it.
8. clean all sufaces, replace both o-rings.
9. CAREFULLY! install the new pump with the special tool. be careful that you turn it all the way in counter-clockwise but that you don't pull too hard. The pump has steel tabs that lock into grooves in an aluminum housing. if you damage that housing by forcing the pump too hard you will cost yourself a ton of time and money.
10. re-assemble the engine in reverse order as disassembly.
don't forget to use your torque specs. You are working with aluminum castings

Bad water pump


Hello: To replace the water pump on the 4cylinder engine you will need a special tool to hold the water pump drive gear. If you don't hold the water pump drive gear the balance shafts will be out of time (rough running engine) the front cover will have to be removed, the timing chain removed. BIG JOB..... This information is for the 4 cylinder engine. If you have a V/6 it's not that big of job. For the 4 cylinder it would be best to let a professional who has the special tool, do the job.

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.
