Q:Suppose the liquid temperature range for the water pump is -20 .. 90 °C.?
YOu need to provide sufficient inlet pressure so that cavitation does not occur.
Q:What does the pump lift mean?
The pump head is the height or length of the distance from the pump to the outlet
Q:my car sounds like it wants to start up but it wont turn over. happened after i changed my water pump?
From the info you give, I would have to say, MAYBE!
Q:what water pump is on a 1978 mercruiser 170hp 224cc 3.7 liter?
Something in your description doesn't add up. Mercruiser did not have a motor branded as 170 hp in 1978, only 85-86. The 224s where a Mercury invention, all about the same for around 15 years. Do you you have a ser #, much more accurate identification.
Q:m azda mx6 it overheats after I drive 20 minutes, I think I need a thermostat and my water pump changed?
First check the water pump for leaks and wiggle the shaft to check for bearing wear. If either is present replace the pump along with the thermostat. If not only replace the thermostat. If the radiator is boiling over after a short drive, the thermostat needs replacing.
Q:Any advise on what would be the easiest way to replace a water pump?
Honestly having the Chilton or Hayes repair manual will help greatly in understanding how it should all come apart. They run about $25.00 at you auto parts store. Having the proper tools will make the job go as smooth and quickly as possible. Most basic kits and be picked up at auto part stores for around 65.00 bucks. This is the best advice I can give a beginner who has just jumped right in there. Watch what you are taking apart and make sure that it is something that HAS to come off. There is no reason taking something out of the car if it's not going to help the project. When you picked up the water pump did you make sure to get too new radiator hoses? I will often replace the upper and lower hose when I do water pumps. Most likely they have been on there as long as the pump and it's time to change them. Not to mention now would be a great time to replace the thermostat on the engine as well to allow proper water flow through the engine. Also make sure you have the distilled water handy with the anti-freeze. Using distilled water keeps the radiator from becoming clogged with minerals that are normally found in your city water. It helps extend the life of your cooling system. I hope this helps. If you have any more questions feel free to E-mail me.
Q:How long will a bad water pump last?
A leaking water pump could be caused by a bad gasket so it does not have to be changed. Changing a gasket is cheaper. If the leak is due to a crack or a pinhole, then by all means have it changed otherwise you risk a crack of the cylinder head caused by overheating which can cost your thousands. You can get a reconditioned or 2nd hand water pump and can save you money. Just ask your Napa store. Typically, second hands are 20% cheaper and can last for years. Good luck.
Q:why is my truck overheating after a new thermostat and water pump?
id say its the radiator after all what ya replaced. have it checked out at a shop. before ya do though ya might do a complete flush of the motor and the cooling system. might be a blockage in a water jacket in the motor. ya can buy the flush kit at any parts store, its simply a T that ya splice into on of the heater core hoses,hook up a water hose,turn heater on, and wait with the engine running. if theres any blockage it will spit and sputter till its pushed out with the water pressure. let it idle till clear water comes out then drain and add coolant. try this first with water only and if it doesnt solve your problem id say ya need a radiator.
Q:how many consequence hours can I leave my water pump working?
You are correct Amps x Volts = watts and since there are about 750 watts per Hp then you have a 2/3 Hp motor. Water pumps can be either submerged in the well bore hole or located top side. A top side well pump relies on the air around it to cool the motor. THe motor may not be rated for continuous duty (see name plate on motor) and may only be rated for a limited amount of time it can be run before it needs a cool down period. (Typically motors are rated for continuous duty) Submersible well pumps are located under water in th well and use the water in contact with the motor housing to cool them. Cooling is thus related to the water flow around the motor and the availability of water. Normal well pump usage for a home is for brief periods when water is actually being used and to maintain system pressure. So unless you are constantly watering your lawn your pump should cycle on and off as necessary. Continuous running is a sign that there is a problem such as a leak, worn pump not achieving proper pressure, or pressure switch setting or similar issue not allowing proper shutdown. If you have a submersible well pump it will be very difficult to tell when it is running unless you can hear the motor contactor open and close or have an indicator light. A properly operating water system will pressurize an accumulator storage tank (water pumped into a tank which contains an air bladder that can be compressed). Once the tank is pressurized the pump shuts off and stays off until the pressure in the tank drops. Pressure drops when you use water or if the water leaks back into the well. At which time the pump runs again and tops off the tank. So in a properly operating system shutting off the well at night won't save you much because the pump should not be running. However if you have a leak and the pump is running a lot you can secure the power to the pump at night until you can get the system repaired
