Visit the autozone.com website and register the car information. It doesn't cost anything and you will have access to an online repair manual for the car. The steps for replacing the water pump should be available there. It's a handy resource. Hope this helped and best wishes.

Id like to give exact instructions, but unless you have just changed one in the last few weeks thats a bit tough. I would suggest a manual that they sell at most local part stores. They are vehicle specific and will help with more than just the water pump.

How do you change the water pump on a 1998 buick skylark?


Hi This is d_hubbs: Removal and replacement of your water pump.I'm assuming you have a 2.5 Engine.You did'nt give your engine Information but about 75% of your Year and Model had the 2.5 in them.
1st start by disconnecting your negative cable on your Battery. Then Drain your Coolant into a Container: then remove your drive belts remove your fan from the water pump: You probally should also remove your alternator and A/C Compressor to make it easier to get to your water pump, now remove your lower Radiator Hose, then remove your water pump mounting bolts, now remove the water pump: Now Clean the water pump surface on your engine where your gasket will be. Besure its Clean Good : NOTE: Sometimes if you purchase a New water pump it will not have the drive belt pulley on it. if this is the case Remove your Pulley from your old Pump and install it on your New pump : now Run some gasket sealer on your new water pump where the gasket will go.put gasket on the new pump lining up your mounting bolt holes.also put a small bead of sealer on the engine where your water pump will mount: now Mount your New water pump to the engine with the Mounting Bolts.Torque the Mounting bolts at 25-30 Foot Lbs.
Inspect your Drive belts and Hoses its a good time to put new ones on if needed.Now put your lower Hose back on-re-install your A/C compressor and Alternator-Put your fan back on-now put All your Drive belts back on be sure to Adjust the Belt Tension and Lock down the Bolts.-Fill your Radiator back up with coolant,If the Fluid you took out is still fairly new ,you can use it. If its Aged best off putting new Coolant. Replace the Battey Cable Start your Car and Check for any Leaks , After your Thermastat opens you'll need to recheck your Coolant Level. if no Leaks and Cooling System is Full you Are Done. Please let me know how my advice and Solutions have Helped you. Thanks for Using FIXYA From d_hubbs

My 2002 Buick Rendevous has a hot coolant


Install the new thermostat (make sure it is the right temp). This will allow for your coolant to stay long enough in the radiator to cool down.

If that does not fix it, check radiator cap, belt that turns the water pump and the water pump itself along with its pulley.

There is also the possibility that the coolant temperature sensor is giving off false readings, that the coolant system is clogged or your engine fan is not operating when it should be.

Change water pump on 1999 Century Buick


GM Century/Lumina/Grand Prix/Intrigue 1997-2000 Water Pump - REMOVAL & INSTALLATION

3.1L and 3.4L (VIN E) Engines
  1. Disconnect the negative battery cable.

  2. Partially drain the cooling system into a suitable container.
  3. Remove the drive belt guard.
  4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.
  5. Remove the drive belt. Please see .
  6. Remove the water pump pulley bolts and remove the pulley.
  7. Remove the water pump bolts and separate the pump from the engine front cover.

To install:

  1. Clean all parts well. Use care when scraping gasket material from the front cover and the pump. Do not gouge aluminum parts. Clean the bolt threads well. The torque specification is low and if the bolt threads are dirty, an accurate torque is not possible and leaks are likely to develop.
  2. Using a new gasket, install the water pump to the front cover. Install the cleaned and lightly lubricated water pump bolts. Torque to 89 inch lbs. (10 Nm).
  3. Install the water pump pulley and bolts and torque to 18 ft. lbs. (25 Nm).
  4. Install the remaining components in the reverse order of the removal process. When refilling the cooling system, use the proper mix of DEX-COOL® and water. Check for leaks.

3.4L (VIN X) Engine
  1. Disconnect the negative battery cable.
  2. Partially drain the cooling system into a suitable container.
  3. Remove the coolant recovery reservoir.

Changing water pump 2000 ford focus


Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it.
If you have basic mechanical skills and tools you will have no problem replacing a water pump.


As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it.
However no matter how good our explanations are it just can't compare to a good repair manual.
A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right.
I personally like Haynes Manuals.
I hope this helps.

Round machined hole in water pump housing leaking coolant


The hole is there to let you know the antifreeze seal in the pump is leaking. You need a new (or rebuilt ) pump installed immediately. Please change the belt and any tensioners while you are at it...

Water pump leaking


Instructions for this are too long to write, though it's pretty much a "remove stuff, then put it back together" operation. Location & removal varies from engine to engine... I strongly suggest that if you don't have mechanical experience, get a repair manual and follow the instructions. Remember to change thermostat and unless your coolant is fresh &clean, add new when completing repair. The price on most new pumps is fairly close in most cases to that of a rebuild... Consider using new as failure rates on these are much lower, right out of the box!!!
Good luck
