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?

Q:We bought a second hand Rover 75, three months later head gasket blew. This was replaced but blew again due to original wet liners. A reconditioned engine was then put in but head gasket blew again due to original water pump. I am not trying to ascertain blame i would just like to know which is accurate as car seller is saying fault of mechanic as should have changed wet liners and water pump and mechanic is saying it is not common practice to change this parts when you replace a head gasket or engine. Thanks for any clarification, especially if you are a mechanic yourself.

It seems excessive to have to remove the engine to replace a head gasket. But I typically work on American cars, and I've seen the inside of an Altima, it is quite cramped. If I were you, I'd search google for replace head gasket procedure nissan altima and see what it comes back with.

Q:to see if it is pumping coolant

If your radiator has a cap you can take it off when engine is cold. Start the car and notice the gently flow of coolant and then after the engine warms and the thermostat opens, about 10 minutes at idle, the upper hose should start feeling warm and the coolant should flow faster past the radiator opening. If you don't see the rushing coolant the impeller of the water pump isn't working. Hope you don't have a leak but you can lose the bearing in the water pump without losing the seal, so there is no leak.

Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?

1, frequency conversion water pump is based on ordinary water pump. The so-called common pump means without any automatic control device of the pump, only the pump head and the motor and a base. The power supply is switched on (default: 220/50Hz or domestic power single-phase three-phase 380V/50Hz) run off, stop. Ordinary pumps do not refer to a particular type of pump, can be centrifugal pumps, pipe pumps, vortex pumps, multi-stage pumps and other pumps commonly used.2, the variable frequency pump, is supplemented by a one-way valve, pressure tank, inverter, constant pressure water supply controller, sensor, valve or electrical components in general based on the composition of water pump with automatic function, and automatic constant pressure frequency conversion water supply device. The input power of frequency conversion water pump can be single phase 220V/50Hz or three-phase 380V/50Hz, but the motor of frequency conversion water pump is usually three-phase. The incoming line is a single-phase 220V variable frequency water pump. The motor is a three-phase 220V motor, the input line is three-phase 380V, and the pump motor is three-phase 380V.Two, the differenceAccording to the definition above, the difference between variable frequency water pump and ordinary water pump is obvious. The main differences: first, the frequency pump has automatic function and constant pressure; ordinary water pump does not; second, variable frequency water pump is a unit, the price is much more expensive than the ordinary water pump.

Q:the pump inlet how hard is this to replace i know the timing chain cover has to be removed and is this the propable place of the leak

You can't fix it. Wanna' know why? You are here.

Q:My husband has a 78 t-bird and it has steam comming out of it. He replaced the water-pump 2 to 2 1/2 yrs ago. The warranty was only for 1 year should it need to be replaced this soon?

Years is the wrong way of looking at it. You should look at in mileage. And it depends on if the replacement was a new or re manufactured. Remans last about 1/3 the time (or mileage) of a new. Be sure to check the entire cooling system and fix the problem. I've seen people replace entire cooling systems ( radiators, water pumps, thermostats) only to find out it was a head gasket.

Q:What does the temperature range of the pump mean?

Not be too cold or hot water, will be frozen.

Q:hi, how long does the water pump last on e65 chassi 745i (miles)

Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
