Q: I have 2004 Chevy Trailblazer V8 4x4 that the water pump went out on. Does anyone know how long it takes to change it and where it is located? The dealer wants $750.00 to fix it. I really don't want to get riped off.: Takes a special tool,you can pick one up at Autozone or Checkers for under 50 bucks, or just pull the water pump with the fan still attached and take it in for them to replace it for a small fee when you buy the water pump.

Q: So I purchased this car last week. It ran great for three days until it started leaking water so much that it caused it to over heat. My uncle checked it out for me and said it was either the seal or the water pump. Yesterday we replaced the seal and still leaking water. So we now know it is the water pump. My uncle and every mechanic I know has turned down the job saying it is too much work. I even called two small shops yesterday and got turned down saying it was too much work. It is Sunday so most mechanics are closed. Can anyone give me an estimate on how much this will cost. The problem is everyone is saying that the pump is located inside the timing belt which is hard to put back after replacing the pump. Anyone ever have this repair done before or know a price range. I am a college student and need this car running asap and only got about $500 i can put into it. It is a V6 engine.Thanks: 91 Plymouth Acclaim

Q: Assuming that my water pump standard flow is 20m3/h, tolerance value requirements is + 8%, then is not traffic 22m3/h is not qualified?: Only half a year after graduation. Professional stuff is forgotten...I can't help you...

Q: I have a 73 dodge charger 400 cubic inch engine, The water pump broke (causing the fan to chew into the radiator) I replaced the water pump and fan (will be replacing the radiator this week) But the problem I am encountering is the belt for the water pump is lose, How do I go about tightening this?: If you dont know how to tighten the belt, I would get it to a shop and let a professional replace the belt for you. You loosen the two bolts, stick a prybar in and tighten the belt, and then tighten the bolts.

Q: The plumber has disappeared on us with 99% of the job done. Our new basement remodel has baseboard heating installed, a water pump attached to the furnace/boiler, but no heat downstairs because their is no thermostat. I haven't checked to see if he did any wiring. (Wouldn't that be an electrician's job?) I've ordered a wireless thermostat kit, and I'm assuming installation instructions for the base are included, but it hasn't arrived yet. What should I do to get that pump pumping hot water to keep us nice and cozy?: That part in the picture is a high limit control with manual reset. It has nothing to do with the pump. You will need more than a thermostat to control the added pump. When you have more than one pump the system is zoned .You need a switching relay panel (Taco SR502) that not only turns on the pump , but also the burner. There is a lot to know here and it's best left to a heating contractor.

Q: Could someone tell me the procedure for removing & installing a water pump on 97 buick skylark 3.1L 3100 SFI?: Water Pump Removal Disconnect negative battery cable. Drain cooling system. Remove air cleaner (if necessary). Loosen water pump pulley bolts. Remove serpentine drive belt. Remove water pump pulley bolts and pulley. Note position of locate tab on top of water pump for installation reference. Remove bolts, water pump and gasket. Installation Apply thread sealant to water pump bolts. To complete installation, reverse removal procedure. Fill and bleed cooling system (fill reservoir and radiator, run engine until upper rad hose starts to become hot. Top off and replace cap) Torque Specs Water pump bolt................89 Inch Pounds Water pump pulley bolt .....18 Foot Pounds

Q: or how do i remove the water pump?please xplain: You need to get the large nut lose. It holds the fan/fan clutch to the water pump shaft. After you get that off it's all down hill from there.A large adjustable wrench will work on the nut but you will need to keep pump from turning to loosen it. I think it may be left hand thread. It is not on real tight. The book will help on this one.

Q: I just replaced my water pump.fixed.. A week later I've been noticing he might of over filled it because.were the coolant goes.steam comes.out.the little.while plus water.. And.before.I.started my.car I noticed.it was all empty now and my.engine sounds like a mini diesel when it runs.. What's the deal? And I.already filled it up with coolant again: Anytime you replace your water pump. You should replace the thermostat and gasket. Also check the upper and lower radiator hoses to see if either one of them are collapsed.It wouldn't hurt to replace the radiator cap.

Q: Hi,My problem is of this automatic water pump ,it is disrupt always I don't no why..I also want to knew what is the function of the pressure air tank??? The picture is here:: WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....

Q: Hey I need to pump water from a river and use be able to use it through a hose and also make the hose have pressure. I was thinking pump the water into a barrel and into a hose or something from there? Anyone know anything about if this would work? What would I need? thanks: buy a submersible water pump. they are the best and longest runing with high pressure. also they are portable and u can take out any time. they are applicable in sea , rivers, very deep pumping etc. but remember to wrap it with a light and silky cloth to prevent the sand going in to it before use in sea and rivers. u dont need a barrel or tank. As they re not heating,they can work continuously even for a years.u can operate from a distance, much pressure than any centrigugal pump. hope it heps. good luck.........
