Q:motor overheats but no leak. water just boils in resorvoir. is it hard to do it on my own?

ummm please make sure you have proper coolant and not just water in your rad

Q:Is pumping water, the new pump is also this problem, the pump is also working, that is, no water, at night I opened, in the installation of water, second days also make it to noon is not so good

You pump 1. is fully automatic, 2. have small pressure tank 3., stop valve should be 1., tap water is interrupted, 2. water intake, water out of harmony

Q:The flow of the pump will be reduced, the speed will change, the power of the motor will change?

Water pump flow rate, speed will not change, the power of the motor will change in general.Different types of pumps have different flow power curves. Only the most common centrifugal pump is used as an example to illustrate the relationship between the flow rate and other pump parameters. The typical centrifugal pump flow power curve is shown in the P-qv curve (red line) shown below.Turn left and turn right |According to the flow power curve, it can be seen that with the increase of the flow rate, the power increases linearly, and the power decreases linearly with the decrease of flow rate.In fact, the pump shaft power P= P gQH/ (1000 K), including H: head, unit m, Q: flow unit m3/s, ETA: for the efficiency of the pump, general 0.7-0.85, P: shaft power, unit kW, K: matching coefficient, small power is 1.25, P: work is like a water medium density.Therefore, for a specified pump, the power is proportional to the flow theoretically. In fact, as the flow rate changes, the efficiency of the pump changes, so it can only be close to the positive proportion.Running water pump speed generally depends only on the pump, power (motor, diesel, etc.) speed, the flow of water generally can not affect its speed. But in the design of pumps, the flow is related to the speed, and other design parameters remain unchanged, the pump speed is high, the pump flow.

Q:When the pump is connected in parallel, will the head and flow change?

Parallel pump should lift the same head, the flow is the sum of the flow of a single pump.

Q:I'm going to be purchasing a laboratory distillation kit here pretty soon, the kit includes everything I need for the setup but the condenser requires a water pump to circulate cold water around the coils. What kind of pump would you recommend for this purpose?

The only thing you might need a pump for is if you are distilling/refluxing something and it is not all condensing before it reaches the end/top of the tube, resulting in vapor escaping. In that case you would use a bucket of ice water with a submersible pump.

Q:What is the reason for the overload of the water pump indicator?

If the power is normal:1, the pump is indeed overloaded (at work to see how much the ammeter indicates).2 、 the motor is out of order.3 、 the thermal relay is not adjusted properly or aging.

Q:i need to change my water pump on my vw 1990 gti. the more details and/or pictures the better or links i can go to to show me

Buy a repair manual. Or better yet buy a lifetime replacment one at Autozone and they will print out a step by step (with pictures torque specs) instructions for you. :)

Q:Was I supposed to lube the water pump or what. I really don't know what it could be making the noise now. But it goes away after about 5-25 seconds of running, what could it be?

If your car is a Chrysler product it is most likely the bearings failing in the idler pulley on the belt tensioning arm. I have replaced this after failure on 2 dodge mini vans. Don't wait too long, if it fails completely the belt will be ruined and leave you stranded.

Q:Today I was installing a new water pump on my 1999 grand Prix. When tightening the bolts one of them snapped off. Now the pump leaks from that broken bolt. I was wondering if I would be able to stop the leak using some sort of sealant or would I have to take the car in to get the bolt removed?

The bolts around the pump have several reasons and one of them is for proper mounting, another is when engine cooling system and block expand when engine is running gaskets dont leak, ect. Yes, that bolt has to be removed, so that bolt hole can be used. If you have enough mechanical ability to remove and replace the pump, with the proper tools, you could do it.

Q:What do water pumps do on a car?

The water-pump circulates the hot coolant from the engine to the radiator where it is cooled and back to the water-pump through the hot engine again. If you had listed a particular car or truck as an example, some water-pumps push the hottest water in to the radiator through the lower radiator hose where it is cooled and then circulated back through the upper radiator hose to the cylinder-heads first then the block. This is the latest and greatest coolant circulation method because the cylinder-heads are the hottest part of a water-cooled internal combustion engine. The block temperature is always substantially cooler than the cylinder-heads. This is called a reverse cooled cooling system. One of these days to avoid confusion the makers of water-pumps should re-name them simply coolant pumps Race car engines are the only place real pure water is circulated through the cooling systems because antifreeze cuts cooling efficiency.
