Q:Where is the water pump in this truck?
on the front of the engine..running off one of the belts
Q:My water pump went, and car overheated. Can there be any other damage?
Overheating your engine is never good , but are you certain it was actually overheated or just a loose wire, faulty thermostat or other giving erratic readings.. If the Engine did not SMELL hot, if the engine performance did not change, if it did not overheat to the extreme...and quickly, it was probably NOT the water pump. Too, it probably did not damage the engine if it was overheated only to the degree that you say. I would wonder about the water pump scenario. Is it possible that you were in extended stop and go traffic in hot weather, and/or your radiator fluid was low and basically getting air in the system.? I hope your mechanic is competent and honest, and the problem was as he said. Usually there is NO Question in the symptoms that the Engine is overheated (regardless of gauge reading). The OIL would get very thin and HOT as well. Just wondering. Good luck.. P.S. I just read Avatar Country Boy's response after I submitted mine. He has some good advice too. I would add that if the engine ever overheats and loses water (or needs water) DONT EVER POUR WATER INTO A HOT OVERHEATED ENGINE !!!!! If you got the radiator cap off in the first place without getting scalded or WORSE, if you try to add water it WILL essentially EXPLODE back in your face as it hits super heated cooling system parts, and most likely crack your engine block, and/or warp your engine heads...serious engine damage. Instead, let it cool completely Again...Good luck..
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
Strictly speaking, eleven kilowatts or more is not allowed to start directly
Q:Why is the water pump smaller than the pipe diameter?
The size is only a matter of convenience or experience, and a small number of tubes are already available. As long as you can pick it up, you can use it.The so-called thick pipe to reduce resistance is a certain relationship. But it shouldn't be your decision to choose the big one. Then why don't you choose the big three? Four or the thicker ones?! @! The resistance will be smaller!!!!- - - - - - - - - - - - - - layman; look at the knowledge of fluid mechanics!!!The question is a conclusion, explain why not one or two words, learn the knowledge of fluid mechanics to know why -- try to answer it, that is to improve the water pump outlet total pressure head, intuitive feeling is to have enough pressure to pump out the water pressure. As for the big three or four, it is necessary to ensure that the flow velocity in the pipe is more uniform, otherwise the flow near the pipe wall will flow or flow too slowly due to viscous action.
Q:How long can you drive with a bad water pump?
The water pump will not spray coolant over the engine bay area. This is a sign of a heater hose split, which is far easier and less expensive to repair. But, call your manager and tell you you wont be in until the car is repaired. Driving it this way will overheat the engine and cause even more potential and expensive problems. See if any neighbor can help until you can get to the repair shop or just tow the car, this will save your engine to last many more useful years. good luck.......
Q:Is it really necessary to replace the water pump with the timing belt?
Its not necessary but still you should replace both at regular intervals as prevention is better than cure, To know more, you can call at (204) 275-9256 or visit the link:
Q:What are the categories of pumps?
Did you say the pump voltage is 220 or 380?
Q:Is water pump working?
You have essentially two correct answers, but looking at the year of your engine I would like to add some clarity. If memory serves, the 1972 engine doesn't have what we today think of as a tell-tale. Meaning that nice little stream of water that comes out of a tube on the starboard side of the engine. Using my poor memory I believe there is and exhaust port, usually one or two outlets together, centered in the rear of the engine, just below the fiberglass engine cover, maybe a little lower. And again, if memory serves, water doesn't flow in a stream from there, but kinda comes bubbling/spraying out. This will be the place to check for exhaust water, and whether or not the impeller is working. Also, like the idea of using the earmuffs, just in case there is thru-hub exhaust you can see it also. If the hub is in the water you can see it exhaust water.
Q:Water pump seized in my car..... what could it seizing cause?
well... depending on how severe the problem is, it could be many things. You could simply have to change the water pump, and be on your way. That's the best case scenario. Though, in really bad cases, I've heard of the whole engine having to be replaced. When the water pump stops working, the engine doesn't get cooled properly. So it heats up a ton, and things start to expand. The pistons can start to gouge the cylinder walls, and ultimately they will get so tight that things can't move. That's what the mechanic was talking about. Also, the water expanding could cause some internal gaskets to blow out. So there are a lot of variables at play here. Best case, it's nothing serious. Maybe as little as $100 for a new water pump (depending on the type of car). Or worst case, you fried the engine and need a new one. That can get quite expensive obviously. Hopefully, it's nothing serious.
Q:are duralast water pumps any good?
Point blank, ask the folks at Auto Zone where this water-pump was produced. If it was re-manufactured off-shore leave it on their shelves. I trust you knew these Duralast water-pumps are re-manufactured. All AC-Delco starters, alternators and water-pumps are re-manufactured in the USA. Every part inside the reused housings are factory brand new with parts made here in the US.
