- Q: My 2001 300M is behaving oddly. Occasionally it will gradually overheat after I have driven around for 15 or so minutes. Yes, occasionally. I took it to my mechanic who changed the thermostat and hoses. I then drove it on a trip on the interstate and over a mountain (140 miles ) It was fine with no signs of overheating. Then the next day when I drove to work in the city, the stop and go traffic had it overheating near the end of the trip. I've been able to keep it from going in the red by using the heater. After this happened most of the days, but not all, I took it back to the shop. He reported that the fans were working correctly and the only thing he could come up with is a weak water pump. He stated that when it did get hot, he was able to bring the temp down just by rev'ing the engine a little.Does that sound right? Any other ideas and how to test?
- The only reason to replace a water-pump on such a new car is if the weep-hole on the bottom of the water-pump in-put shaft casting is leaking. If your upper radiator hose if hot when the dash temperature reached 195 degree's there is nothing wrong with the water-pump. Cooling systems plug when brand X antifreeze is mixed with the standard equipment, long life type. *Did your mechanic do an inexpensive *cooling system pressure test to look for external and internal coolant leaks? Is the radiator filled to the very top when the engine is stone cold? Is the plastic coolant recovery bottle at least 3/4 full when the radiator cap has been removed? Have you checked to see of the electric cooling fans are operating behind the radiator when the dash temperature reaches 205 degrees? It's less expensive to change the thermostat and radiator pressure cap than a non-leaking water-pump. An 11 year old car is do to have the cooling system drained flushed and *cleaned before having Fresh factory recommended ZEREX G-05 antifreeze added.
- Q: Give me a general intro. about submersible water pumps.
- A water pump can have all the works above the water, pulling by suction and pushed by atmospheric pressure to a maximum of about 33 feet. Or it can have the motor above water and the lifting mechanism below with a long rod connecting (like an oil well with the donkey engine on the surface), but a bunch of weight and friction. Or it can be waterproofed and the motor and pump lowered down the drilled shaft on a plastic pipe with an electrical cord along side and push the water up. The last is a submersable. Similarly sump pumps and recirculating pumps where the cord, motor, and pump are under the liquid.
- Q: Would a bad water pump make a whinning sound when the engine is reved.....ive checked everything off as to why my car is running so hot and im down to the water pump.....ive put a New thermostat....no leaks anywhere.....no oil in coolant....no coolant in water.....no white smoke.....Fans do turn on.....new colant and i bleed the air out.....but the engine is still running really hot....my car calls for about 13 quarts of coolant but upon refil it took only about 4 quarts...... .. . uld this be signs of my water pump failing.....the pump is not leaking and when i took the housing off the water pump and turn the engine the blades did rotate...but at a higher rpm with the car together i heared weird noies kinda like a whinning sound from the water pump.....1995 Oldsmobile Aurora194,000Northstar 4.0 V8
- the water pump some times whine when it goes out.the radiator could be plugged.when running sqeeze the top hose to make sure its ciculating.this will let you know if its the water pump is out or not.
- Q: We are leasing land from a friend to put horses on. We're in the process of building a barn. We don't want to run water out there because its too much trouble for the meter and everything, but someone said to get a water pump and pump the water from the pond and filter it and use it. I have no idea what all we need or what kind of pump to get. Helpp!
- There are many choices and lots of problems. You probably can use a small system with garden hose even depending on how much water you need. There are a lot of variables to define. How much water ie gallons per day? How far do you have to pump it? Is it uphill or downhill? What quality is the pond water? Filtering is a little harder but you should find in line systems or something on the web once you determine the flow rate etc. That may determine the rate you can pump at ie the filter capacity. Do you have electric? If not you need a gas setup pump or generator. What kind of storage tank are you going to pump water into? Sounds like your filter will be the big thing. If you pump 100 gal thats about two bathtubs full. If you pump that in 100 minutes that is 1 gallon per minute. Thats small. So if you can find a filter to do say 1 to 10 gpm and that type pump you can do two bathtubs or more in two hours or so. If you go to 10 gpm thats about the max for a garden hose. Thats more what you would want to spray from the system. Your filter is the key. How clean is the water? Then you need a pump for the flow rate and pressure that can go through the filter. City meter sounds easier now doesnt it?
- Q: 2 pumps in parallel, lift the same, the pump head is not stacked; 2 pumps in series, the same flow, pump head is not superimposed?.
- 2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.
- Q: How do you measure and analyse the pump characteristics and efficiency?
- An automotive water pump consists of a steel shaft with an impeller (like a steamboat paddle wheel) on one end and a pulley flange on the other. The shaft spins on bearings located in a cast iron or aluminum housing. The housing has internal passages to allow the water to enter the impeller cavity and exit, often to a tube like structure (part of the housing casting) to which one of the rubber radiator hoses attaches. How it works is simple. Water present in the impeller cavity is confined and pushed to the outlet by the rotating vanes of the impeller. The rotation of the pump is usually driven by a belt powered by a pulley on the engine which turns a second pulley mounted to the pumps pulley flange. The characteristics might include things like, is the pump self priming or is it self lubricating? In an automotive system the answer to both questions is yes. To evaluate a pumps efficiency you would want to set up a test rig where you attach the pumps outlet to a long hose and use it to fill a calibrated container (one gallon, five gallons etc). Then with a stopwatch you can either time how long it takes to fill a gallon container or you can measure the volume of water pumped in a minute. Either way you will get useful information you can use to evaluate the pumps efficiency. You should repeat the above test at different engine RPM's to discover if the pump has peak efficiency (or lack of efficiency) at a particular RPM or range of RPM's. Finally, if you do this experiment for real be sure you add water as fast as you pump it out so you don't over heat the engine and damage it. Have fun.
- Q: The water hose hooks from the radiator to the water pump. Does an o-ring go in it? What else could be causing it to leak?
- it is either a loose clamp or a bad hose
- Q: I think my water pump has crapped out on my 1997 Jeep Cherokee. I have been leaking coolant for a few days now and there is a puddle under my Jeep after I turn it off and my reserve tank keeps emptying out on me. I replaced the lower radiator hose and still the same problem. It is not over heating so I am wondering if it IS a water pump problem? If it is, could I do the work myself?
- Go okorder They have on-line repair manuals for just about every car. You'll be guided through entering your vehicle make and engine size/type. Find the water pump and read the directions they give you. I changed the one on my Buick this way. It's cheaper and easier than buying the manual. If it looks to complicated, then take the car to a shop.
- Q: Why can't sprinkler system and hydrant system share water pump in fire fighting system?
- Why not share mainly because the two impurities contained in the water system: fire hydrant system requirements of different impurities in the water spray system requirements loose, but more stringent requirements, therefore, the former can be welded steel pipe, the latter must use galvanized pipe, the purpose is to prevent rust plug flow indicator or end of the spray head.
- Q: The water burst how to repair?
- If it is not too serious, with casting glue on the line, it is best to use serious brazing, don't use the electrode,
