Question:

1999 malibu 3.1 v-6 water pump???

the question i have is can the pump be turning and not leaking but not pump water??? i know the olden days (the good ole days) as long as the impeller was turning it would pump water! leaking seal is when it went bad,or locked up..like a box fan blade as long as it is turning its moving air...

if you have allergies.. you're gunna have some respiratory problems if you do not get the car interior douched by a professional
Yes, the impeller could be broken. Believe it or not, the belt could be on wrong. If by chance it was replaced recently, it is possible to put the belt on the wrong side of the pulley. It should be running on the bottom side, not the top-next to the little plastic cover.
some vehicles could have a loud water pump without extra issues. often times a defective water pump might reason problems with the cylinder head if the engine overheats. So examine right here: one million. is there steam in the exhaust smoke? 2. Do drops of water look on the tip of the exhaust? the two between the above can mean a warped cylinder head or blown gasket. if it is so, do no longer purchase. in case you have any concerns, get the motor vehicle regarded at by a mechanic.
I would first check to see if there is any circulation in the radiator, with motor cold and the radiator cap off start the engine and wait about 10 min watching the radiator opening there should be some circulation if not then you probably have a bad water pump or a stuck thermostat that is stuck closed
Why not check the flow of coolant in your radiator. When the motor is cold remove the radiator cap, drain two cup fulls of coolant from the drain valve on the bottom. Start the car and when the top radiator hose is too hot to touch watch for flow of coolant directly inside the open radiator. You may need a small flashlight to watch the coolant. if there's no movement after 10 minutes idling two things could be wrong: Thermostat stuck shut or the impeller is in fact broken inside the water pump. Do the easy stuff first. Good luck!
