Q: I have had this water pump changed 2 times in 5 years is this normal for this car? It has a v6 motor.: no it is not normal for most cars but maybe yours it is..

Q: how do I know my water pump failed. 98 mustang V6 started to leak coolant from the front lower part of the the engine. How do I know for sure my pump is bad? Did refill and kept on leaking as I manage to get home. Little help please!: There is a weep hole on water pumps that will leak coolant when the pump goes bad. The housing could be cracked or there could be a leak in the gasket. When it's running, see if you can see where the coolant is coming from.

Q: How much should I look for paying for my 1998 Honda Accord Water Pump??? With Labor and Materials?: Your okorder /

Q: Water pump is STILL constantly running! Since this past thursday, we did:new check valvenew pressure controlnew foot valve (well)well is not dryprime, air pressure are finewe have above ground pump in the basement. we called a plumber and he could do nothing! we have water and pump/tank and everything seem working fine.But the pump is on and off every 30 seconds - 1 minute. It is so annoying and out of ideas what could be wrong.My husband think it could be the tank and suggested that we replace it. But the plumber didn't say anything about the tank. And it is not too old.Do you think it is the tank and we need to replace it? If so, we will do it on this Sunday morning even though it might cost extra charge! please help!!!: you have what is called a water logged tank!! that means you are not putting enough air into it to act as a pressure source for the water,, this makes the prsessure switch kick on and off constantly,, if you have a bladder in your tank you have to add air thru a bicycle like valve usually on top of the tank,, if no bladder then you have to drain all the water from the tank and then screw everything tight before you turn it on to refill with water!! the air in the tank will compress then!! or or pressure switch was not bled right!!!!

Q: In 2005, the water pump, export pressure in recent years decreased year by year, the running current is increasing, there are 4 pumps are like this. Professional personnel advice please!: Export pressure reduction generally 2 reasons: 1, blade wear, 2. mechanical seal leakageThe increase of electric current should be caused by severe wear of the friction pairs of mechanical seals, resulting in increased resistanceIt is suggested that mechanical seals and blades be changed.

Q: I think its the water pump, I fill the coolant with water everyday and it is empty once I make it to my destination.: I know this isn't exactly what you asked but if you have the v6 engine changing the water pump on this car is a very easy job. There is a video on youtube that shows you exactly how to do it, just search water pump gm 3.1. Just be sure to get all of the old gasket off and use rtv on the new gasket. You could probably change it yourself for less than $50 and 1 hour if you can do basic car maintenance.
