Q:Why does my water pump switch on and off about every 5 seconds?
It sounds like the bladder in your pressure tank has ruptured.
Q:The wiper pump is broken. How much will it cost to fix it?
Hello, the wiper motor is broken, can only be replaced to solve the problem, different models of price difference is too large, general average car about 60-80. You can go to a few repair shop to ask, OK, you can also match the city or Taobao purchase.
Q:Water pump motor overload
If the power line is too long or too small, power line is too long or too small will cause excessive current. Valve shut down certainly affect the flow. When the valve is in the semi open state, the water pump out of the water flow down, the power to reduce, so the current drops.
Q:How do i know if my car water pump is working?
How To Test Water Pump
Q:Pump power ratio design is small, the problem is big?
The flow is 20 L/S! Q = 20, L/S = 0.02 m^3/SThe total efficiency of the pump and the motor is estimated to be 60%P=pgHQ/n=1000*9.8*90*0.02/60%=29400W= 29.4, KWLook at the water pump motor power 30KW just enough from the calculation, but there is no room for the use of the attention do not overload!(Note: motor power matching pump nameplate are generally too large, room.)
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
Filter pump for oxygen spray. If the filter pump water flow, you can throw oxygen flowers, you can not use. With that pipe, it's loud and kind of
Q:clutch fan or water pump?
well if it is the water pump you will have a small hole ( tale tale hole ) and it will be leaking water to let you know its out. and clutch fan there will be alot of play i have seen people stop them with there hand but i dont advise it
Q:what are the symtoms of a bad water pump?
Agree with motorhead. You (question asker) replaced the pump, did you see anything that could break? Only issue with GM water pumps is normally if the cooling system is abused and fluid never changed, which can lead to the impellers rotting away. If the water pump fails fails (not just a leaking seal, the normal failure mode) the engine will overheat. The waterpump is the only thing that moves coolant, if the coolant can't move, the engine will fail from overheating. Take the belt off and see what happens for yourself. Did you purge the cooling system if needed? Did you use a genuine AC Delco thermostat instead of whatever the parts store handed you (probably Stant)?
Q:How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?
Check the thermostat, if that's the problem you'll be looking at a 5 or 10 dollar bill if you do the work yourself.
Q:water pump kicking on all the time!?
similar problems with mine a year ago..and I eventually called in the water well professionals..It ended up being the pump itself on the end of the pipe down in the well..I then replaced the toilet fluidmaster and flapper anyway!
