Q: how do u know when u need to replace ur water pump or how do u know when its not working??? thanks
Water pump may have three types of failure: 1. Leaking shaft seal You know by a. puddle under the car, b. low coolant level, c. ultimately - overheat 2. Shaft bearing failure You know by excessive noise, play in the shaft, ultimately - leak from the seal (see 1) 3. Turbine itself breaks. This is a rare case, and the only one that represents no working condition. The engine immediately - withing a few minutes - overheats.
Q: I just bought a house and we have well water. When I went out to change the filter on the pump I noticed a valve leaking...I went to check on it and noticed it had two settings if you will. one says System and the other says by pass if I move the lever to system the leak stops, if I move it back to bypass the leak continues...question is which one should I have it set on and what is the purpose?
Okay, Adam, we also have a well and just put in a new one. The setting that says System means that the water is running through the filter. The setting that says by pass means that the water is NOT running through the filter. You will have water either way in your house (or you should). It is just either, it is running through the filter, or it is not. I hope I have helped. gram
Q: Hi there: my water pump is leaking, and my coolant lelel keeps droping, same problem. Im not sure if coolant flows through the water pump?
You will probably need to replace your water pump. It supplies all of the coolant for your entire engine
Q: or how do i remove the water pump?please xplain
You need to get the large nut lose. It holds the fan/fan clutch to the water pump shaft. After you get that off it's all down hill from there.A large adjustable wrench will work on the nut but you will need to keep pump from turning to loosen it. I think it may be left hand thread. It is not on real tight. The book will help on this one.
Q: I have a 1997 mercedes 320e and it is leaking very bad. I need a temporary fix for the water pump, so that I can take it to the repair shop that is 10 min. away.
old mechanic trick get pepper and pour it in there/use a whole box if you have it/works
Q: I have a 2005 Mazda RX8 and I was wondering if upgrading the water pump on my car would void the warranty I have with Mazda. I know such modifications such as air intakes and exhaust systems do not void warranty. The Magnuson Moss Warranty Act says Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle. So is it safe to say it's alright to install? Thanks!
put it on...what if the stock pump wore out...you and most others will not put a gen u ine mazda pump on it...in reality its replaced with a aftermarket pump
Q: i have a problem with what i think is my water pump, and i was wonder if anyone had any websites that have free engine diagrams, and if it is my water pump, it turns on and off when at idle, is that normal, if not, what could be the problem?
The Water pump does NOT turn on and off at Idle, that is the electric fan and yes, that is normal. Do you have a heating problem? It is UNUSUAL for the water pump itself to cause heating issues unless the impellor is damaged or it is leaking. Good LUck
Q: WHERE IS THE WATER PUMP LOCATED ON A 1995 HONDA CIVIC
Hello, okorder
Q: Why should the water pump be opened in time after the pump is started?
The circulating water pump outlet valve is closed when starting, normal after the water outlet valve is opened, I found that, with the valve opening, the current is slowly sinking, you tell me why?, and the other is the opposite of the pump (with the valve opening current increases).
Q: If you use a water pump to move water through a circular trench, essentially making a little river, and then place some kind of turbine or water wheel or something to generate electricity from the moving water, couldn't you use the electricity generated by the turbine to power the pump, thus requiring no outside power?
All the energy that you can get from the stream you have created will always be less than the one you are using to drive the pump that feeds the stream. In engineering field you must get into your brain that Perpetual. motion machines just does not exist. you can use it to understant thermodynamics processes when using in simulated problems but it is only ideal situations.
