Q:What does the pump lift mean?
The pump head is the parameter you must know when you buy a pump, that is, the height of the pump.To buy a pump, I think the Heathrow pump is OK. I bought it earlier this year. It's not bad yet, but the quality is pretty good.
Q:Water pump runs a lot?
No there should be a pressure adjustment switch, low around 30 when it switches on and high around 50 when it turns off. Also check air pressure in tank
Q:took car to mechanic put in timing belt engine coolant and water pump now green fluid leaking what is it?
green fluid is antifreeze. with the hood open start the car and look under the car to see where its coming from...then look up top at the hose connections,,,,,personnally i would phone the mechanic ands have him come out to the car so you dont overheat it and blow the motor.he shouldnt charge you for this as there has to be warrenty...i think he just ddidnt tighten a clamp or screwed up the water pump gasket
Q:Mercruiser 3L 4cylinder (water pump problem)?
This is your recirculating pump. If it is a marine pump, it will have a brass backed seal and no heater hose outlet. (have seen them in the casting, but no hole there) The only difference is the casting, as long as it was ordered for the boat, you should be OK. For got to ask, do you have a cabin heater in the boat?
Q:How to check a water pump on a 1998 Dodge Dakota V6?
plugged heater core? the fact that the hose gets hot lets you know that the water pump is circulating coolant.
Q:My car squeaks every time I turn it on. But the belt is tight and I have a new water pump and alternator.?
no, there's no lubing the water pump. You can have a dry bearing or worn bearing in your Alternator, power steering pump, A/C pump, etc. All these can contribute to a squeak or squeal that can drive you crazy. Glazed belts are another thing, did you check the other belts when you changed your water pump belt? is it a serpentine belt that does it all, or do you have 2 or 3 separate belts? Usually if the noise goes away after awhile, it's a bearing problem.
Q:96 Beretta Z-26 water pump?
You probably have the 3.1 v-6, so the pump is not really hard to change, and is a belt driven pump.
Q:What is the function of a submersible pump?
Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.
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:How do i replace water pump on a 2005 v6 mustang?
Drain the engine cooling system. Remove the air cleaner outlet pipe. Loosen water pump pulley bolts. Remove the accessory drive belt. Remove the water pump pulley. Remove the upper and lower radiator hose. Remove the heater hose. Remove the 12 attaching bolt and remove the water pump. Clean and inspect gasket mating surfaces. To install: Install the water pump. Use a new gasket and tighten the bolts to 89 inch lbs. (10 Nm). Install the heater hose. Install the upper and lower radiator hose. Install the water pump pulley. Install the accessory drive belt. Install water pump pulley bolts. Install the air cleaner outlet pipe. Fill the cooling system. Start the engine and check for coolant leaks.
