Q:I need information about basic water pumps. I'll have to build a mechanical one for school. Do you have any ideas, information, designs, links? Thanks!
A very simple and old design for a water pump is called the ball-chain or bucket-chain pump. A google search should show you what they are. Building one should be fairly straightforward and simple.
Q:Here is the deal...*Van over heats*Blows Cold quot;heatquot;*Coolant leaks (not into the oil)*Added coolant and water (nothing happened)*Started van, felt the hoses (no h2o flowing thru)Ive had this problem for a while. Some times my van drives just fine and heats just fine, then some days it wants to over heat and blow cool quot;heatquot;. Adding coolant to my van used to do the trick, but now its not working. If it is my thermostat that is broke, the water/coolant would still run through the hoses right?I really think its my water pump out, but I am not sure. Does this sound like my water pump? If so, I plan on changing it myself, how do i find step by step instructions to do so.... I have never done it before, but I cant afford to take it to a mechanic! Thanks for your help!
Again, see last answer to your same question. You obviously dont know what the real problem is, could be water pump and might not be. Instead of wasting over 25.00 on a water pump and that not being the problem, why dont you take it to a reputable repair facility and have the cooling system analyzed and they can tell you EXACTLY what part(s) need replacing, then go from there. Nobody can diagnose your cooling system problem over the internet since we are not at your vehicle with a coolant pressure tester and block test tool.
Q:I'm just wondering where I should buy my new water pump for my 2.2 cavalier? Auto zone, carquest, checker? Does it matter which one?Thanks
They all buy their water pumps from the same manufacturer. Beware !!! Don't trust the location of the weep hole from the original pump to line up the replacement. Don't trust the directions on the new pump to find the top for alignment. Unless the new pump lines up perfectly, rotate it until the bolt holes line up PERFECTLY. If the bolts are hard going back in, the pump is misaligned.
Q:I have a cabin cruiser and I recently took it out of storage and had it de winterized. Now everything seems to work except for the fresh water pump for the sink, shower and toilet. Does this type of pump need to be primed? If so how do you prime it? Thank you for the help.
Try hooking a solid 12 volts directly to the pump to 'jump start' the pump.. That got mine started... As mentioned in another post, these pumps are disposable items.. Good luck...
Q:water pump
Flow? Head? suction pressure? Type of pump if that matters to you? You'll get better suggestions if you provide as much information as is relevant.
Q:Have a Toyota RAV4. About 156, 000 miles on it.Yesterday as I started driving, there was a sound coming from underthe hood that sounded similar to a stick in bicycle spokes. Got to theend of the block and stopped and noticed there was smoke comingfrom below the belts.Got back to the house and the temp was up really high. No fluid.Added fluid and water and it was leaking, but not from the radiatoritself, but from towards the back of the engine?Might this be the water pump?
Nope, could be a bad heater hose that burst. Could be an engine gasket but it will be more issues. I am more inclined if is like you described towards the back of the engine, is the water hose for the heater or the valve that controls the flow.
Q:Water pump
well thats gana depend on the year and engine size but i would say that you can plan on spending between 30 and 70 dollars
Q:300M head of 11 stage centrifugal pump with 22KW motor, empty (not water) current of 13A, the water into the pump, current up to 44A, open the outlet valve of the current rising to 100A, immediately shut the gate current is up to 170A, the motor stop. Without any problems, not on the impeller pump shaft is not clean the shell the balance sheet, no wear, bearing normal.
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q:I have a 99 Olds Intrigue With the 3.8L (Vin K) engine. I have a belt driven water pump, but i was wondering if there is a fuse or relay that is associated with this water pump. I remember knocking a fuse out on accident while changing my radiator and now the water pump appears to not be working
Get back in the kitchen woman!
Q:Went to bring my car in to get all my belts replaced (minus the timing belt) My car was working fine, nothing was wrong with it. I pick up my car and get it home when I turn to get into the drive way there's this horrible squeal. I bring it back to Pep Boys and they tell me my water pump is broke. Now I don't know anything about cars, but is there a belt that they replaced that does something to the water pump? Please if you know about cars let me know. Thanks
not there fault . just bad timing
