The 2001 Oldsmobile water pump is located on the front of the engine. You can follow the top radiator hose directly to the water pump.
The Oldsmobile AleroThe vehicle that replaced the Achieva was Oldsmobile Alero (produced from 1999-2004).
a 2002 Alero could have several problems causing the overheating. Thermostat, water pump, or clogged radiator issues are the most common causes of overheating.
Drain radiator through plug at bottom or rear of radiator Re-fill radiator with a 50/50 mixture of antifreeze and water slowly to prevent an air lock
It is located on the passenger side on the bottom of the engine near the firewall.
it looks like a little coolant jug that comes on the bottom left side of the dash
it happened cause the time needed for the lime water to change was made less
first lose the belt the the four ten mm bolt and you move the pully and lose the six 5/16 bolt
Sounds like a bad water pump to me.
Coolant level low, thermostat stuck, clogged radiator, defective water pump, blown head gasket, or cooling fan not functioning.
Your best bet would be to go to an auto parts store that sell Haynes Manuals. They are not very expensive. It will help you in many other matters.
I had the same issue with a 2001 Alero and the Oldsmobile repair shop installed some sort of deflector inside of the door. Not sure what or where exactly but that is what they told me.
