Q:We have a 92 cadillac deville, my husband can replace the water pump he justs need to know if you have to jack the motor a little. Please help before our car blows up!!

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: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 need to fit a booster pump to increase pressure from a gravity fed vented solar water heater (uses vacuum tubes).The problem is that the temperature of the water from the solar panel can be very high - in fact it could boil under some circumstances. It's safe because the system is vented.As the quot;solarwater feeds existing water heaters in the house, diluting the hot with some cold prior to the pump with an automatic mixer valve is not really an attractive option as we want to gather as much hot water as possible.Can anyone tell me where to get a booster pump that can operate at up to 100 Deg C, delivering 2 bar pressure and about 25 liters per minute. Thanks.

Yes you can as per the other answer . Make sure when you do you dont exceed the Gallons per minute of the cellar pump or you will burn up the pump on your house . Also make sure that the pump in your moms house can only pump up to 50 psi . Most well pumps can pump higher but that is the setting on the presure switch You might be able to change the tank and switch in moms cellar to a bigger presure tank and up the presure on the presure switch and cure the problem that way and not work the well pump so hard by turning off and on so often .

Q:i have a 1994 honda accord lx. i was wondering what the water pump is for and if it goes bad can i still drive around without it thanks

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.

Those pumps are usually self priming.. either you have a PLUGGED LINE or the water pump froze in the cold and it needs to be replaced... but they are cheap.

Q:How large is the starting current for a 1.5 kW submersible pump?

1KW about 2 current, so the rated current is about 3A, and the starting current is usually 3-8 of the rated current, that is 9-24A.

Q:Because the water pressure is too small, this summer with self suction pump 750W, water is big, but every time that water is used for the first time out of the water is yellow like rust, probably after the release of 10 liters will become clear, then is not, but every one hour after the water time out is rusty hair yellow, so to waste a lot of water, but accidentally brought cooked food should not be good to the body.Now come in the water is through the pump, even without electricity, partition time for the first time water will be yellow, there is no master can teach me to disassemble, which can be cleaned?. Or something else. Thank you

The pump is iron, must be able to avoid the internal rust, and if replaced by stainless steel, no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.

Q:Difference between primary hot water pump and two hot water pump

A hot water pump is a water pump circulating between the boiler and the heat exchanger, and the two hot water pump is a circulating water pump between the heat exchanger and the user. That is, there is no relationship between a water pump and heating users.

Q:I would like to use water from the lake to water my lawn. My lawn is about 100 feet up hill from lake. Just want something I can attach a garden hose to. what type of pump and horsepower do I need.

With 100ft of rise your probably going to want a deep well pump. Which means 3/4 to 1hp pump. You'll need a 230V electrical supply on a 20 amp breaker possibly 115V on a 30 amp breaker. This means buried electrical. You could try a cheapo pump and just return it if it dosn't work. Try to figure out the real rise from the lake to lawn. If it's a shear drop of 100 ft, sounds like a deep well pump or similiar.

Q:ok water can't sucked up more than 10 M height in normal atmospheric pressure some well s are deep more than 10 M even some water aquifers are deep more than 200 m what are technologies used to pump water to ground level BQ- how is crude oil pumped from far deep oil wells (some offshore oil platform pump oil from more than 2000 m deep ocean and another several hundred meters deep from sea beds )

You push it from the bottom. Home water wells have a plastic hose and a power cord along side and the pump is attached to the end and lowered down the hole and pushes the water up the hose. Oil wells are commonly pressurized, but where not that donkey engine you see in oil fields is attached to a long rod or cable and at the bottom of the hole is a pair of valves and a piston and the mechanism pulls the oil in the lower valve and pushes it through the upper valve and that pushes the previous oil up the pipe.
