Q:I have a 2007 Chevy Silverado Classic with a 4.3 liter engine I'd like to replace the water pump on the truck?
this is not that big a deal, this engine is 3/4 ths of a chevy sbc 305, which is basically the same as small block chevys from 1955 forward-the good thing is that this can be done quite easily in the car, just remember this engine has a serp belt, so take note of where the belts go and how the pulleys are aligned with all the accessories. DO NOT break the seal on the a/c unit, just take off the compressor and set it to the side, same with the power steering and alt. Once you get through the pulley system, just remove 4 bolts on the front of the pump, remove it, you have already drained the coolant, and keep it, either reuse it or dispose of properly, remove the pump, and clean off the old gaskets from the front of the engine block. Take the old pump with you, get one that is the exact same as the one you took off-do not allow the old pump to be taken by the parts store, buy an all new unit, not a rebuilt, and keep your old one until the new one is installed and functions properly-I know, I am probably overly protective, but many times I have brought home what appeared to be the correct pump, and it did not work, then I did not have my old one to look at to see exactly what i needed...good luck, as far as the paint, well, use a solvent to soften whatever is stuck to the paint, if it in fact is concrete, not cement as that is the powder that concrete is made from, then try a little vinegar, it is slightly acidic, will dissolve the concrete, and the spot can be removed gently, hopefully without chipping the pain-here is the good news, concrete does not chemically bond with paint, so you should have no problem...good luck, be careful.
Q:1997 jeep wrangler water pump?
$70-$150 +cost of pump. Most shops have certain maintenance hours for certain jobs. Call around for exact pricing. Honestly, if you have a sockets (metric) and wrenches you can do it yourself in about an hour or two, maybe less. You don't have to mechanically inclind to replace the water pump on the 97 Wrangler. If you do it, I do recommend buying a Haynes/Chilton's book if you don't really have a clue. If you need to buy the tools, book, pump (gasket should come with it), water pump RTV, and coolant. That will still be a lot cheaper than paying somebody. Plus, you will get the joy of doing it yourself. Also, you could put the savings into a high-flow pump, vice original equipment.
Q:How can you drain a pool without the use of an electric water pump?
Hey, your idea about buckets and a bunch of friends sounds like fun. Have a pool draining party! Get a case or two of beer, grill some hamburgers. Then everyone in the pool and have fun. Of course tell them to bring their own buckets.
Q:Where online can we find a small water fountain pump?
fountains are us
Q:Why would a newly installed water pump leak?
Take it off again and inspect the metal around the hole it is going in. Make sure there are no gouges or major damage. Besides that have a friend do the seal. I know what I am, doing and sometimes just a different method, or a new set of hands does the trick. That is probably the problem.
Q:can I use copper spay gasket to seal my water pump gasket on my truck?
Sure, why not? Usually, the metal area when most water pumps are bolted too are cleaned with a scraper of some kind and old gasket matter is removed. That surface should be cleaned, flat, and free of irregularity. Most mechanics, if they use any kind of stickum - like contact cement from a tube, or the costlier, but not-needed specialty sealers, is applied to the pump surface so the gasket stays put and not move when installing the bolts. The glue does not do any actual sealing, just the fiber gasket will. None needs to be applied to the engine side that you scraped clean. Make sense to you? It's probably a good idea to service the cooling system with a non-caustic flush cleaner before hand -since all the coolant will come out during the change. Then add a additive that neutralizes acids with the new anti-freeze.
Q:How many kinds of pumps are there? What are the advantages of soft start?
The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.
Q:Would a missing bolt in the water pump make it leak?
/i thini it might... I would just get a bolt from a local carquest, autozone, aidauto where ever cant be anymore than 5 bucks... best best better than overheating your engine and getting stuck for a couple of bucks
Q:what's wrong with my water pump?
what the hell are you working on?? Need just a little more input
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
