Q:1994 honda accord lx water pump what does it do?
the water pump circulates the coolant through the engine so that the heat is moved from the engine block to the radiator where it is given up to the outside air. the circulation of the coolant is what keeps the engine from overheating. if the engine is overheating you shouldn't drive the car as it could cause the engine to seize if the water pump is 'bad' it won't move the coolant through the engine fast enough and the engine will run hot. That usually doesn't happen. What does happen is that the water pump seals wear out and they leak and the engine won't run for long with all of the coolant leaked out. the bearning in the water pump do get noisy over time and they could get real loud. Typically the worn bearing will cause a seal leak (see above) before the pump seizes. most shops change the water pump when they change the timing belt. On that car I think the timing belt and water pump were to be replaced every 90,000 miles hope that helps
Q:When is it necessary to replace the timing belt and water pump on a 2001 Mazda Protege?
That could have either the 1.6 liter or 2.0 liter engine. My information shows that if you have the 1.6 liter, at least you don't have to worry about bending valves against pistons if the belt breaks -- you'll just be stuck out on the road until you can get it towed and fixed. Not so with the 2.0 which is an interference engine. So if you DO have the 2.0, pay attention -- you don't want an expensive breakdown! You're on borrowed time at 75K. For both engines, Mazda recommends that you replace the timing belt every 60K miles. Gates (a major replacement supplier) seems to think these belts will go 105K. Since it's a factory belt, stick with 60K. As for the water pump, it's often one of those while you're already in there sort of things when you're doing a timing belt. 60K makes it a tougher call, especially with the better quality of water pump bearings and seals. If your interval were 80K ~ 100K as is true on some cars, I'd say go for it without blinking. As cheap as it'll be (it's really just the price of the pump), and it was my set of wheels, I'd do it anyway, even at 60K, if it needed to be pulled to do the belt.
Q:The reason why the pump is overloaded
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q:what do you need to do to remove water pump?
I believe if you are looking at the motor the water pump will be to your left on top of the motor and to the front. Drain the radiator. There is a big smooth pulley that turns the water pump loosen the 4 10mm bolts, remove the belt the remove the bolts. Under the pulley there will be 5 or 6 8mm bolts remove those, make sure a drain pan is under the pump because there will be some residual coolant in the motor. Scrape the old gasket off of the engine block then reverse the procedures to install the new pump. Make sure you torque the pump to the proper specs so that the pump housing does not distort. You can pick up a Chiltons manual for that car a local parts store that can walk you through this in greater detail with pictures. Good Luck

Q:water pump in 99 cadillac sts?
Yes because it what allows the engine coolant to flow to keep the car on the right temperature.
Q:Bad alternator or bad water pump pulley?
Well from your description I would say it's the water pump, as that is where the residue is but if all the pullies are spinning by hand I would suggest gtting a throwaway belt and looking for yourself. Also if you had any overheating problems before than I would lean to the water pump, or if you had any dead batteries or charging problems I would lean to the alternator then. What about the A/C compressor that could also be the problem, so could a tensioner as well. So I stick with my original statement and try to get a cheap belt and look for yourself, just make sure you wear protective glasses so if it does snap you dont lose your eyes actually just be careful when you do it OK!!! Good Luck, Tony
Q:Water pump pressure for shower?
if your sink does not need a pump, you shower won't either....most water systems are pressurized
Q:99' toyota camry 4 cyl. water pump?
camry requires special tools and not easily accesible. timing belt is a '' good idea for a 99
Q:water pump problem,heats up only when i drive?
The short answer to your question: It is unlikely that a water pump will go bad without leaking, but weirder things have happened. Your thinking is right overheating only when you drive is an indication of limited flow, either caused by a restriction (radiator, hose, thermostat), an air bubble, or a bad pump. Are you sure that the air is bled out of your system? If you have an air pocket in your engine or at the pump, you will get reduced flow. I think that the 4.7 Durango has a radiator cap, if so, with the engine cold, take the cap off, fill it, and start the engine. If you get bubbles every time you rev the engine, then you may have a bad head gasket, this would introduce bubbles in the system... Make sure that the lower radiator hose is not collapsing. Most of these hoses have a stiff spring inside to keep them from collapsing when the water pump is running. Otherwise, my guess would be that your pump is bad, or you have more restrictions in your system. Good luck.
