Q:My 1990 Ford f150 water pump is leaking from 1 spot underneath. It is brand new, What's going on?
if its leaking from the weep hole then u have a bad pump.....return it and get another.... if its leaking from a seal or from the silicone ....u will need to remove it and reinstall it......this time make sure silicone is evenly spread ......
Q:Car still overheating with a new water pump, thermostat?
is your cooling fan working? my guess is it isnt and thats why you overheat. theres a thermal switch for the fan... that may be bad or your cooling fan motor could be bad
Q:What does water pump mean?
The pump is the pump, and pump the water where you want it
Q:Where is the water pump located on a 1999 cadillac deville?
2 or 3 hours of labor depends on the shops labor rate if it is a northstar it is on the drivers front of the engine by the rad hose (inside the crossoverpipe) or if it is the older engine it is on the pass side side by the drive belt (thin and long)
Q:how to convert a deep well pump to shallow well?
Gould Shallow Well Pump
Q:Physics behind this PVC Water Pump?
It isn't practical to give a detailed description here. This is a positive displacement pump. The pump chamber is sealed so that as the piston is moved up the volume within the chamber increases. Water is pushed into this chamber by the outside air pressure. If the pump is located too far above the water source then the air pressure is not sufficient and you will produce a vacuum inside but the water still will not flow. When the pump is pushed down the water flows out. Now the one way valves are critical. We don't want the water to flow back the way it came and we don't want the water that we have already pumped to flow back into the pump. So a one way valve on the inlet will permit water to flow into the pump but not out of it. And a one way valve on the outlet will permit water to flow OUT of the pump but not into it. So with each stroke you a) reduce the pressure in the pump. b) water is forced from the inlet, past its one way valve and then into the pump. c) the pump is pushed down increasing the pressure in the pump. d) water flows out of the pump through the other one way valve and on to the output.
Q:how much is it to replace timing belt and water pump?
Two engines were available in the 2002 Voyager - a 2.4L 4 cylinder engine and a 3.3L V6 engine. The 4 cylinder was timing belt driven but the V6 uses a timing chain with no set replacement interval. Replacing the timing belt and water pump in the 4 cylinder is going to be $500-$850.
Q:Water pump leaking after replacing coolant recovery tank?
water pumps go out all the time and we have no control over them.It is a good idea to service the cooling system once a year,draining the radiator and flush out the complete system .But anyway when you replace the pump it would be a great idea to do just that being that winter is coming up in a few months.Also you never mentioned what type of vehicle you are talking about,someone else mentioned a timing belt ,it really depends on the year make and model but that is some good info also. I hope this info helps ya out.
Q:need a new water pump?
It is very easy and straightforward. The hardest part is the fan clutch unless you have the proper tools. You have that part covered. DO NOT USE ANY SILICONE SEALER!!!!! Be sure all traces of old gasket are removed and install the new gasket dry. Use an anaerobic sealer on the wet bolts. Those are the ones that are through drilled into the water passages. Clean off the threads then use a light coat of sealer. I use either Permatex (brown stuff in the tube) or pipe joint dope. Now is also a great time to flush the system, replace thermostat, and drive belt(s).
Q:what is wrong with my car? is it the water pump or something worse?
it may be the waterpupmp but the again it may just be flow valve. Take your car to the dealer and have them look at it. If it's the flow valve then you save a lot of money.
