Q:Cant get the bolt loose fromthe fan that is attached to the water pump in my ford ranger. need to remove bolt in order to remove water pump.

You take a wrench that will fit behind the fan, and knock with a hammer on the wrench to break the nut loose. You turn the nut to loosen it the same way the fan turns when the engine is running

Q:What will the water pump reversal situation?

The same will reverse pump water, but the head and the pressure greatly reduced, I just finished debugging a pumping station, Stephen multi-stage pump, installation of equipment: multistage water pump motor power 4 75KW 76% head 100 meters, frequency control, motor nameplate nominal current of 143. According to the direction of the motor steering pump mark OK set the start time of 28 seconds after 5HZ boot head start frequency can reach 50 meters (at that time did not install the pressure gauge cannot observe the water pressure of current) in early 118 about 3-5 minutes after the current is reduced to about 97, there are inspection found no problems, suspected pump problems, suspected foot valve not completely open, the reason cannot exclude the end of valve, almost in despair when the thought is not marked in the direction of the pump, re set to restart the current 129.5A to observe that later installed capacity reached 0.55MPa duct pressure gauge head close to the design requirements, the problem on the manufacturer's mark is reverse.

Q:Water is pumped out of a holding tank at a rate of 6-6e^(-.09t) liters/minute, where t is in minutes since the pump is started. If the holding tank contains 1000 liters of water when the pump is started, how much water does it hold one hour later??Round your answer to one decimal place.

Q:My radiator light came on this morning i was running late for work so i topped it off with water (about twice a year the light comes on, it has only ever had to be topped off) and after about 20 minutes of driving it started to heat up, so i pulled over shut it offsomebody stopped checked the temp of the water in the reservoir, said it felt to only be about 100 degrees, but topped it off with more water. the gauge dropped right back down to being almost as cold as when you first drive it, but after about 2 miles it was right back up near the red line.I pulled over again there was steam coming off the engine. I stuck my finger in the water it felt warm, but nowhere near hot. I couldn't get it cool enough to finish driving to work. Does this sound like the water pump?If so, how long should this take a decent mechanic to replace?If not, what else could it be?

sounds like u have air trapped somewhere or a flow problem water pump not pumping or thermostat not opening do not keep driving it b/c further costly damage can occur this shouldn't take more than a day for a good mechanic

Q:water pump has small leak

Remove the pump and remove the harden rubber gasket all around it and put a permanently elastic sealing compound/sealing compound then reinstall the pump, good luck!

Q:I have some black RTV silicone that I got with a gasket for my oil pan. Can I use some on a gasket for a water pump instead of regular sealant or is there a particular type I need? If there is a certain or preferred type please give me a link to it at like autozone or something, thanks!

Sealant or silicone is usually used instead of a gasket. A gasket is made to seal and does not need any other kind of sealant. If installing a gasket and you do not want it to move then you use a glue, but just enough to keep the gasket in place. Glue like 3M. If installing a Eng. oil pan gasket where it takes a rubber end or an intake manifold gasket then you use a silicone where the rubber meets the paper or cork gasket. This is for insurance only. Some oil pans don't use a paper gasket then you use a silicone. Lay a good 1/4 inch bead around the block and let it get tacky then carefully install the oil pan. On the water pump, it wont hurt to put silicone to hold the gasket in place, and also insurance in case it leaks Good luck

Q:I have replaced the presure switch on my water pump but it switches on and off when it is building up presure instead on staying on until it gets to right presure.Any ideas of what is causing this?

The switch may have gotten some debris in it. Try removing it(again) Clean the passage way out. If possible try running the water a few seconds while this is off to clear any debris than reinstall and check. It also could be low pressure in the expansion tank or a bad bladder in same.

Q:2000 Jetta GLX VR6Problems:- AC is no longer working- The Reader said quot;STOP!quot;CHECK COOLANTI pulled over and checked the Coolant and it was full- The Car will overheat to about 260 whenever I am sitting with the Engine Running- When I start the car its on Zero Degrees and then Slowly makes it way to 190 degrees which is in the middle quot;Normalquot;- Oil Seems to be fine---- What does this sound like to you??--- Also, The VW Dealer said I needed to be without my Car for Two days so I will drop it off Friday Night and leave it until Wednesday. Do you think it will last until Friday driving 60miles a day??-- If it is the Water Pump... How much do you *think* I am looking at paying? I am taking it to the VW Dealer b/c I have a Recall they need to fix too.

This does not sound good. If it is the water pump, there is a very good chance that you will severely damage the heads and/or block by continuing to drive it. I would not drive it at all, unless you want to risk the expense of a re-built engine (more than $5000 plus installation). If it is the water pump, and not covered under warranty (and I would really get on them about that) less than $1000.

Q:I have a 2000 A4 1.8 T with 91 k miles on it. I went to the dealer for my oil service. I told them that I hear a quot;clinkingnoise when I start the car and that it goes away after the car runs for 5 minutes. I told them to check this also. They diagnosed and said that the water pump has gone bad and needs to be replaced. Since it was close to 105 K miles, I might as well change the timing belt. Total charges for both is 1250. And they also see that Cam Seals starting to leak oil. Since I was doing the timing belt, I might as well change them too. Additional cost to do them is 950. So the total for all three comes down to 2200. I bought the car at 90 K and checked it at Firestone and they said it was cool. They noticed an oil leak but said it was not anything major that needs to be taken care of right away. Do you think the dealer is taking me for a ride here? I just drove 500 miles and would things go this bad all of a sudden? Or should I make the replacements? Please advise.

these prices are correct for dealership quote. you will get a cheaper price with independent shop. your timing belt should be changed anytime after 75k miles. the timing belt and belt tensioner will break and you do not want to have replace the cyl. head, it's alot more money. the dealership lied about your water pump. that year the water pump runs off the drive belts not the timing belt. you can replace the water pump and not even touch your timing belt. your cam adjuster seal probably not leaking. what happens is the valve cover leaks oil on to the cam adjuster and is commonly mis-diagnosed. try just changing the valve cover gasket, clean up your excess oil and reinspect the seals on the back of your cylinder head after 500 miles. good luck.

Q:i just moved into a house that has a small (about 40 gal) pond. i wanted to put fish in it. i have everything but the water pump. i've been looking around and i've found many solar fountain heads (about $30) that are pretty cheap and then i found a solar oxygenator for $100. which one would help the fish more? flowing water or just oxygen?

To be quite honest, they are roughly the same thing. For a small pond all you need is something to agitate the surface of the water. the carbon dioxide/oxygen exchange only occurs on the surface therefore a small fountain that agitates the surface would work, or a small air pump that causes bubbles. Both are just fine.
