Q:Hello, I have a 1996 Cavalier and it's got a small coolant leak by the water pump so I figured I'd replace it. I called around a little bit and one quote was $250. I'm sord of handy and have a few hours on Saturday is it that hard? I heard it's just a few bolts? Thanks!!
It's easy as hell. Should take about an hour, maybe 2. Depends on how 'handy' you are. Before you replace the water pump, check your hoses. Make sure it's not them that's leaking.
Q:In 2005, the water pump, export pressure in recent years decreased year by year, the running current is increasing, there are 4 pumps are like this. Professional personnel advice please!
The outlet pressure decreases, indicating a decrease in speed. The increase of the current shows that the load has increased. Generally speaking, the resistance of rotating parts increases. Check that the bearings of the pump and motor are damaged as soon as possible. As soon as you replace it, you will be able to return to normal. If this is done for a long time, the motor is likely to burn out
Q:4--6 inch deep well pump head? How much per hour out of water?.
Best answerLift pump is the location of the outlet is high, such as wells 5 meters deep, you put the pumping pipe on the bottom, the pump is placed in the vicinity of well, then, the head is 5 meters, the water power how much you buy depends on the pump, the greater the power, the faster the water pumping. The greater the party...
Q:i have a jetta and would like to know how difficult it would be to do. I know its a german car this is why i ask. thanks
The water pump is driven by the timing belt on that engine. You don't have to take the alternator, power steering pump, or the a/c compressor off, but you do have to make sure it is timed right. Not too hard to do, just make sure the marks line up. Good luck!
Q:Okay, I'm setting up an NFT hydroponic garden and am now looking for the water pump. I would like some suggestions for one that will give a steady stream at a good rate for the plants. But, it must have a minimum lift of 5ft to reach the first level.I would prefer one with a flow rate adjustment but if you could at least make a suggestion to the GPH it should pump for the right flow after a 5 ft climb I could search more in that range for one I like.Thank you!
I think you may want to look at the small pond pumps and just about any nursery or home supply store or landscaping store. they may have the specs on hand, or see if they can demo one for you. some places have a display pond set up already. You also might try a small swimming pool pump and put a voltage regulator in the line and adjust the pump speed that way. maybe rig a sewing machine pedal in the line and use a C clamp for an adjuster. I love rigging thing. It may not work with a gfi plug.
Q:I would like to change the water pump myself but do not have a repair manual.
Do you have the 3.4 or the 3.8? Oh well. No one bothers to give that sort of vital information on here... Don't forget to buy RTV when you go buy the pump. Anyway, the 3.4: To Remove: Drain the cooling system. Remove the drive belt guard if equipped. Loosen the water pump pulley bolts. Remove or disconnect the following: Drive belt. Water pump pulley bolts and pulley. Water pump bolts, pump and gasket. Clean the water pump mating surfaces. To Install: Install or connect the following: Water pump gasket and pump. Water pump bolts. Tighten the water pump bolts to 10 Nm (89 inch lbs.) Water pump pulley and bolt until snug. Drive belt. Tighten the water pump pulley bolts to 25 Nm (18 ft. Lbs.). If removed, install the drive belt guard. Fill the cooling system. Inspect for leaks. For the 3.8: To Remove: Drain the cooling system. Loosen the water pump pulley bolts. Remove or disconnect the following: Drive belt. Water pump pulley bolts. Water pump pulley. Power steering pump and reposition. Water pump bolts. Water pump. Water pump gasket. Clean and inspect the water pump mating surfaces. To Install: Install or connect the following: Water pump gasket. Water pump. Tighten the long water pump bolts to 34 Nm (25 ft. Lbs.) Tighten the short water pump bolts to 22 Nm (16 ft. Lbs.) Water pump pulley. Water pump pulley bolts. Tighten the bolts to 13 Nm (115 inch lbs.) Power steering pump. Drive belt. Fill the cooling system. You're lookin' at eight bolts on the pump in most vehicles your make/model.
Q:here is the problem with my water pump control switch settings. the water is being used, runs dry and stays off for sometimes 3 minutes or so.i realize the springs control the cut in and cut out. do i need to make the spring more compressed to make the pump come on sooner? or do i need to make the spring looser to make the switch come on sooner?when i read/hear about adjusting the cut in. the answers seem vague because i do not know the perspecitve of the spring.does compressing the spring make the swith flip easier? or does compressing the spring make the switch harder to flip on?i installed a new 30/50 switch today. My air tank was at 50 or so PSI. but i dropped it to about 30. is the goeal to make the entire full system 50 pounds? because after my pump cycles i get about 70 psi!!!
The problem lies with the new 30/50 switch. With Your pressure tank empty of water, set the air pressure at 28psi. What is happening is when the water pressure drops below about 45 psi - the air pressure (50psi) on the bladder is forcing the water out rapidly. Then the pump has to work like cracy to overcome that bladder pressure! Easy Fix. Make sure the tank has no water in it.
Q:1997 Chevy Cavalier, 2.2 engine. In the past 2 days I noticed that my temp gauge was reading a little higher than usual but not in the danger range. I checked and nedded to add coolant. Last night it started making a chattering or maybe klunking sound. As far as I could tell it was coming from the water pump but it stopped before I could get out of the car and look to see. Now the coolant is low again. Are these signs of the water pump being bad or could it be something else?
Sounds to me like you answered your own question. I would have the water pump looked at by a reputable mechanic. A thermostat doesn't make a chattering noise when failing. A water pump can make noise when failing. WARNING: MAKE THESE CHECKS WITHOUT THE MOTOR RUNNING! When a water pump is failing, frequently it will leak coolant from the impeller shaft (the shaft that has the drive pulley). Look for greenish or orange liquid leaking from behind this pulley. Also, try to rock the pulley from side to side. If the pulley moves, the bearing and seal are failing and the water pump must be replaced. Have it repaired soon. Replacing a water pump is much cheaper than replacing a burned up engine. Until then, don't take it very far and watch your coolant level closely.
Q:One mechanic told me that my Toyota Corolla 2004 CE's water pump is leaking and I need to change pump and its belt costing me around $450. I took it to other mechanic today and he told that water pump looks good and no need to worry. I need to know how I can verify that water pump is leaking or not. Below are some facts of the car that I noticed myself.1. The engine collant level is above half level about at 70% 2. I started my car around 8.30 PM @ 90 degree F after break of 3 hours and the temprature gauge reach to half in 5 minutes.Please advice what can be done to determine the leak is there or not else I have to take it to other mechanic.
the only way to tell if the water pump is leaking is if it leaves little drips or big puddles if you dont see any drips its probably not leaking just watch the coolant level
Q:I need to get my timing belt and water pump replaced, its been 100,000 km , just wondering, what exactly these things do, i want to know more about my car, and just how much this would cost to take care of, my dealership says almost a 1000, including labour, does this seem right.
The timing belt is the connection to all your other belts. If it snaps while driving it, it will need re-timed with a timing machine. Usually by a mechanic. I suggest replacing that ASAP. As for the water pump, they last a little longer but if you notice your car's temp gage going up in heat every now and then, the water pump might need replaced. good luck!
