How to change Water Pump.

i hope this helps for the water pump. The thermostat is located at top of engine simply follow upper hose to engine and remove housing and replace thermostat.

Put a piece of cardboard under the car. Then look down at the cardboard from above the the area. You can see where the drops are in relation to the hose or water pump or other spot.
I do that for locating oil leaks.
Hope this helps.

some bolts go thru the water jacket,could be you need to add cilcone to the ends of the bolts.

If it is leaking behind it, you will need to replace the water pump and gasket. The new (can purchase a remanufactured pump, cheaper) pump will (should) come with the gasket.
Please let me know if you need assistance with removal and installation.

To change the water pump you need to remove the serpentine belt, remove the pulley from the water pump, rotate the water pump within the housing and replace it. Reinstall, check for leaks.

Sounds like the radiator is OK...if you cannot see any visible leaks...if you have inspected upper and lower radiator hoses and connections...it could be the water pump...however you should be able to see some antifreeze around the water pump pulley...changing the water pump on your Oldsmobile is not a major job...you do not have to remove any motor mounts to do this...only if your serpentine belt is worn and needs replacement...your Olds will require the removal of the upper motor mount in order to change the serpentine belt...sounds like you are on the right track...:)

It is the water pump most likely,they have ,what they call a weep hole in the bottom under the pulley,so they will leak out to let you know to change them right away.If it is on the top coming from the intake area,it would be the intake,they are also bad to leak,but look at the pump,under the pulley.

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.

no, leaking water pump just means it is time to replace your pump. Not continue driving until you get around to it. replace it now. If it is not starting something esle is wrong. Unless you've over-heated the engine.

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...
