Q:I recently bought a 01 firebird trans am. was doing some maintenance on it. basic stuff, tune up, serpentine belt, break flush, and a coolant flush. I didn't notice any leakage in the car, and neither did any mechanics before. Last week when i did all these basic maintenance i went back to check up on one more thing. The mechanic raised my car up and asked when I'm replacing my water pump.Seeing that it was leaking...but the liquid wasn't green, more or less brown and it didn't have any particular smell, but its not coming from the oil pan. What I'm thinking is that maybe the hoses were completely tightened? All help would be appreciated! thank you!

Check your coolant levels. Take a drive and let the engine get warm enough for the thermostat to open. This is easily checked by grabbing the upper radiator hose that comes from the thermostat housing. Be careful because it will be really warm. (Most thermostats open at 165 to 185 degrees.) If that is warm, great. With the car running, while parked on a clean surface where you can see if there's a drip, look under the car. Any dripping? Water pumps will more often show that they are gone without making any real noise. They have a weep hole, a place where when the seals goes, it lets water drip out and this is obvious. Water coming from there will be obvious. If there's not a slow or steady stream of water coming out, then it's likely NOT to be the water pump. Turn the engine off and look for wet spots. Is there water around the radiator cap? Is there water around any of the hose connections. Are there any bulges in the hoses? If nothing is really obvious, go to the auto parts store and buy Bars Leak radiator sealant. When you get home, drain half a gallon or so of water from the radiator. Shake the Bar leaks really well and pour it into the radiator. Go for a drive. Drive for 5 minutes, get the engine heat up and drive home. Any minor leak, even at the hose bib, in the radiator, or in the water jacket will be fixed. This stuff has a guarantee so if it doesn't work, go get your money back. You're looking at spending under 10 bucks, by the way.

Q:I'm going to buy a pump to take water from a lake and use it to water the grass at my cottage. I would like to run at least 2 hoses at the same time. I'm looking at one that's 3/4 horse. Is this too small? The yard is a little more than an acre.

not only do you have to move a lot of water, but you have to LIFT it over a long distance.... you may need a pump in the middle of your distance, as well....

Q:Engine problem 1999 Nissan Sentra 4 cyl Front Wheel Drive Automatic 165000 miles ---------------------------------------------------------------- I have a leaking water pump that has to be replaced. I am calling around getting prices and some people tell me that I have to do the timing chain at the same time and that will be a great deal more money. Can I just replace the water pump? It seems that the water pump only will be about 200.00 but both could be 500.00. Please help

I don't know about a 1999 Sentra specifically, but when I replaced my water pump in my 96 Saturn SC2 I didn't have to do anything timing belt. Unless the mechanic says it just needs to be replaced the two items should not be related.

Q:can you give me some information?

Water pumps come in all sizes from less than one gallon per hour to over 50,000 gallons per minute. They also produce pressures on the discharge from a few inches of water to thousands of pounds per square inch. They pump water with all kinds of contaminates and chemicals dissolved in the water. Finally they can have all kinds of service conditions from a few minutes at a time once a day to continuous operation. All of these factors enter into what you need to have a good quality pump.

Q:What is the influence of the speed of the pump motor on the pump?

Low speed, the pump has a certain wear and tear

Q:Here we have 3 sets of centrifugal pumps, as production water, 2 by 1, because the production is not allowed to stop, so we want to change for a pump, the original two pumps to stop, and three water pumps on the amount, and then stop the pump, but not on the third pumps the amount, do not know what the reason, the master to help, thank you very much..

The problem you are experiencing is stressThe above answer is only considered in the case of water absorptionJust imagine, two pumps are normal work, the same suction pipe, how can there be dissatisfaction with water or vacuum state?.According to my experience analysisYour system is three sets of parallel, lift and flow should be the same, if not the same, not in this discussion, the topic should be set up.Lift is the same, that is, in two or three units at the same time, the resulting system pressurization is the same, and water will increaseBut now your traffic is increasing at two units, but it will not increase at threeYou have selected pipeline system design, in the design of head flow under single condition is constant, if the increase in open water pump, the pressure is constant, increasing water content, according to the continuity equation Q = A X V, then the flow velocity in the tube will increase;But when the third pumps, 2Q becomes 3Q, normally velocity should be larger, but the Darcy formula shows that the velocity increases, extension resistance and local resistance will be increased, and the double square, so you can open third pumps for reasoning, when the resistance effect caused by the pipeline the increase of water flow in the pipeline can not be reused, the general formula of constant current, now the whole pipeline in turbulent stateThat is, third pumps to do the work in the water and pipe wall friction in the loss, and actually did not play a role in water supplyThe solution is to increase the flow rate by increasing the water supply pipeline

Q:How hard is putting in a water pump for my 5-series on a 1-10 scale ?and how do i put it in ? details please !? i dont have a chitlon for it . ive worked a lot on this car and i do know some things about it, but not very car savy. Thank you !!

What is easy for you may be hard for others, so I would not give the job any hardship rating. But the approximate job entails doing these...descriptions from viewpoint of person standing infront and looking towards the engine... a) remove fan blade with fan clutch by turning big nut clockwise (reverse thread) b) remove fan belt, then remove pulley attached to water pump c) remove radiator fan shroud if you can to have more space to work in d) put basin underneath engine to catch coolant and detach radiator hose connected to water pump e) remove 6 bolts holding water pump and remove pump f) clean surface of engine block to remove left over sealant/gasket g) install new pump and other removed parts in reverse order h) add coolant, bleed (using bleeder screws in thermostat housing and upper radiator hose), then top-off coolant to proper level marked on expansion tank near windshield. i) ran engine or roadtest, then recheck coolant level after overnight stay or when engine cools down.

Q:antifreeze leaking from the water pump. antifreeze wont stay in car, car overheating. 96 chevy cavalier. 2.4

So what is your question? If you know the problem, either replace it yourself (which I would NOT recommend), or take it to a mechanic, to have it replaced. On this particular vehicle, it's a major undertaking, since the water pump is driven by the timing chain, if I recall correctly. To access it requires removing the engine mount, and front timing chain cover. Installation requires having the engine re-timed. Although I'm not familiar with GM products, as a rule of thumb, engines that use a timing chain, are usually an INTERFERENCE engine (which means piston/valve damage WILL result, if mistimed). The labour time guides lists 8 hours for this repair on this particular vehicle, with this particular engine. That should tell something, since water pumps are usually listed for about 2 to 3 hours labour on most vehicles. Hope this helps.

Q:What causes a water pump on a car to go bad????? and are they a pain to change by yourself?????

the corrosion is the main cause, corrosion is caused by using water coming by the faucet, that water came with some minerals and stuff and the engine at high temp activate those minerals and react causing that brown water (acid water) so the best way is adding a nice mixture of coolant and destilated water is the best but if you dont have that water at hand use some radiator coolant aditive, it will neutralize the effects of the regular water coming from the faucet making that will not make your water pump last forever but your whole system will last many more years

Q:i need the location of the water pump or for the thermostat thank you

The water pump is timing belt driven and is under the plastic timing cover on passenger side. These water pumps have a history of breaking, due to the fact they have a plastic impeller and it shears off the shaft, which causes the engine to overheat. First you want to remove the thermostat and then check the water pump. Follow the lower radiator hose to where it connects to the engine. That flange is where the thermostat is at. After you remove the thermostat you can shine a light in the hole and put your finger in there, if the impellar of the water pump moves, it needs to be replaced. If it does, then you might as well replace the timing belt and tensioner, seeing how you have to remove it to get the water pump off.
