Q:pulley on water pump has slight wobble. is it bearings going bad?
Water Pump Pulley Wobble
Q:What RPM is required to operate a car water pump?
Idle speed of car at minimum is around 600 RPM.Too fast to pedal.
Q:RV Water Pump Question!?
Rv Water Pump Switch
Q:When should I replace oil pump and water pump
You should not replace them if they are still working. These items can work for ever or stop working as soon as they are installed.
Q:Water pump housing is NOT available at any parts store.?
You should probably try a salvage yard. They might have it, of course it probably wont be new....
Q:Suppose the liquid temperature range for the water pump is -20 .. 90 °C.?
(edited) The physical size of the pumping arrangement was not described. I assume that the pump has all metallic components because of the high (194 F) 90degC design operating temperature. There may be some problem with an elastomeric bellows in a mechanical seal at the 180degC (356F) temperature. Other than that, there should be no problem with the temperatures as far as the pump is concerned. There may be a need for shaft cooling to protect the standard electric motor and possibly the flexible drive coupling arrangement. (edit) Depending on the physical size, rotating speed and drive arrangement, a special coupling set-up may be needed to accommodate any potentially wide swing in operating temperatures. From ambient to 180degC there will be about a 160C (288F) variation. The liquid will be either a salt or a glycol brine solution for freeze protection at the lower temperatures. (edit) That same concentration will provide some elevation of the boiling temperature and therefore a reduction of the pressure of the water solution needed to prevent boiling. ( 130 psig is the saturation pressure of plain water at that elevated temperature.) This can be found on the charts provided by the glycol suppliers for the various glycol and salt solution characteristics. To prevent cavitation you may need to pressurize the suction. If the proposed pressure of the system is already above the vapor pressure of the solution at that maximum temperature, you may already be OK. A motor with high temperature windings may be considered.
Q:Blown head gasket or water pump?
There should be a weep hole on your water pump from where the antifreeze will be leaking if the seal is gone. Clean it up real good and try to see if that is where it is leaking from. Also check the thermostat gasket. If I remember correctly it is located above and just behind the water pump on a 305.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:how to replace water pump on ford focus?
Not very easy, apparently, but probably not as hard as a timing belt driven water pump is (first source). You don't mention the year or engine, but if you plug your actual info into the estimator in the second source it will give you a better idea. I used a 2000 Focus with 100K miles; it looked like 2 1/2 hours of labor (figuring about $100 per hour) for the dual OHC engine and about 2 hours for the single OHC engine.
