Q:Location of water pump in the '97 Toyota avalon?
Front of engine block, behind fan and driven usually by the crankshaft.
Q:what causes water pump failure?
There is a number of reasons for your water pump to leak. One could be its tear and wear due to years of used. Second is due to successive overheating. Weight cant cause water pump breakdown, as long as it does not overheats. To much pressure in the cooling system cause its breakdown. Hope this might help!
Q:High Pressure Streaming Water Pump Needed?
With 100M of 'head' you're going to need a constant displacement pump, and high pressure piping. I'd consider an intermediate lift station.
Q:how to tell if water pump bearing is bad?
No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!
Q:What kind of water pump should I get?
Go to sears and get a shallow well pump that has a foot valve and runs on 115vac perhaps a 1.5 hp ..if the head(the uphill part plus the pipe loss ) gets to great you might need a lager hp but a 1.5 with a 25 ft of head should give 9gpm at 40 psi . Oh yes is this is a closed system be sure an get a high pressure cut off switch..they are real cheap... from the E..
Q:Why does my pool/water-fountain pump shut off?
outdated wiring. Hire a certified electrician to re-wire it. Could be the timer too! Quit messing with it or you could have an electrical fire. Feel the walls near and around the set up box.
Q:Need step by step instructions on how to replace a water pump. Or where i can get a diagram on how to.?
I have done them on the 4.9's. I dont remember having to jack up the motor for any reason. I do remember there are like 20 bolts that hold it on and there is not a heck of a lot of room to get at them. I think the reason someone mentioned jacking up the motor is some of the GM engines like the 3.1 or 3.3? to change the belt you need to take apart one of the motor mounts. Since the mounts hold the engine in you need to support the engine when you remove them. I remember the 4.9 being more like the 3800 in that its mounts go to the front by the radiator so they wont be in the way of the belt.
Q:Variable flow variable frequency water pump how to adjust the flow?
Variable frequency pump is mainly depending on the frequency converter to adjust the speed of the pump motor, thereby regulating the flow and lift pump, the following Q1/Q2=n1/n2; H1/H2= (n1/n2) -, the frequency range of the frequency converter in 30HZ~50HZ
Q:How do i replace water pump on a 2005 v6 mustang?
Drain the engine cooling system. Remove the air cleaner outlet pipe. Loosen water pump pulley bolts. Remove the accessory drive belt. Remove the water pump pulley. Remove the upper and lower radiator hose. Remove the heater hose. Remove the 12 attaching bolt and remove the water pump. Clean and inspect gasket mating surfaces. To install: Install the water pump. Use a new gasket and tighten the bolts to 89 inch lbs. (10 Nm). Install the heater hose. Install the upper and lower radiator hose. Install the water pump pulley. Install the accessory drive belt. Install water pump pulley bolts. Install the air cleaner outlet pipe. Fill the cooling system. Start the engine and check for coolant leaks.
Q:question about water pump on 93 Camry LE, 4 cil?
That water pump is driven by the timing belt. Usually when you do a timing belt or water pump it makes sense to change both now because they are both difficult to get to and you have to take off the same things for both. $385 is a bad price If you want to look smart about it, ask him to look at and check the seals, all he would be able to tell you is if they are leaking, if they are, ask him how much more. It's all worth it if the car is still good. We just did that on a friend's '91 and her's overheated a few times. She ha 235,000 miles.
