Q:how much do new brakes and a water pump cost?
Brakes aren't very expensive if you do it yourself. If it's just pads your looking at $20 and a little d.i.y. If it needs rotors or calipers walk away now. He knows it's going to need a new water pump? Sounds like a recurring issue then. A water pump isn't something you can really spot the wear on until you either hear it beginning to knock or see your coolant on the ground. But if it's doing either of those things the car isn't drivable. Water pump will run you about $70 for the part. Your probably looking around $200 for the part and install. My advice, take your money and walk away.
Q:Which water pump set has more vertical suction / lift.?
PUMP 1.
Q:What are some possible symptoms of a car with a Water Pump that is On its way out?
Steam coming from your headlight on a rainy night is NORMAL, since the halogen bulb makes a lot of heat. This turns the water into water vapor, (steam) as it attempts to dry out. If you don't physically hear the bearings in your water pump, or watch colored fluid drip out from under your engine, then your water pump is JUST FINE!!! STOP WORRYING! I answered one of your questions the other day. If you take my advice, your engine will run at it's best. For extra protection, drain and flush your cooling system out, and use Mercedes coolant. Dex-cool has been proved to be a potentially bad coolant. READ the dexcool litigation websites. Mercedes coolant, which is YELLOW in color, will last for 150,000 miles, and is a time tested WINNER!!! Use ONLY top tier fuels (read about this on web) and use ONLY synthetic oil, like Mobil One. CLEAN your idle air control valve and throttle plate. AND STOP WORRYING!
Q:Well water pump kicking on?
How long does it pump when it turns on? This sounds like short cycling; you might have a leak somewhere in the system.
Q:How do I change the water pump in my ford mustang 98 v6?
If you don't already know how to do it, then take it to a shop to have it done by the professionals. If you insist on trying it yourself, buy a Chilton's manual for your car, do some online research (with pictures), and buckle down. You will need to loosen the belts, remove the belts, remove the water pump, replace it, and reinstall everything. You will need to make sure that the belt is routed the correct way, or BOOM! You might also want to replace the timing belt while you're in there. It makes sense to replace it if you already are removing it, and the timing belt is something you can't afford to have go bad on you.
Q:Water pump make screech noise?
Check if your water pump has an oil port, and put some oilers. The other possibility is that the pump impeller is coming loose or warped and rubbing. That means the pump is going out and needs rebuild or replacement. That is worse case along with a failing motor bearing.
Q:What is wrong with my water well pump?
Sounds like the vertical check valve between the end of the pump line and the pressure tank is bad and allowing the water to go back down the pipe when the pump isn't running. Papaw
Q:How to identify the motor series of pumps
You can also use the motor speed divided by 50, equal to the motor series.
Q:Location of 2000 Impala water pump?
water pump is located on pass side of the motor right where serpentine belt is
Q:Domestic pump does not use water, or turn, I do not know why?
The motor should be kept working, may be the motor switch problem, idling motor pump long time will certainly be bad, ha ha, the solution is to find a water pump maintenance master to work safety first!
