- Q: All water pump have diferent caracteristics, but it is imposible to overcome a certain hight...what is that hight and why?
- If you are talking about the limit on the suction side of a pump then the answer is about 34 feet. This is because due to atmospheric pressure that is all the water can be raised without the portion at the bottom of the column starting to vaporize. 14.7 psia (atmospheric pressure) equals 33.9 feet of water.
- Q: We have just replced our hot water heater in our camper. When we turn on the water pump we hear it kick on and run. When we turn on a faucet water comes out then slowly goes away untill nothing comes out at all. It has been a year since we used the water tank, so its been full of air. The camper is pretty old, i dont know the specific date though. Could it be low water pressur? any help would be greatly appreciated.
- Can't you hook the garden hose directly to the camper? That way you could see if there is air in the line or if the pump is tired and needs to be replaced.
- Q: As I wrote last night, I have a Isuzu Rodeo V6 3.2L 4X4. I guess I misunderstood my husband. I talked to him this morning and he said that it did overheat but the gauges on the inside of the car wasn't showing that it was overheating. It wasn't spewing coolant but the coolant that was just filled up a couple of weeks ago is empty. Does anyone know what the problem is?
- you need to have your coolant system pressure checked asap,by a technician at a shop you trust,,get some friends recomendations,if you dont have a regular mechanic. while you dont list the year,or milage of your izuzu, water pumps can fail at any time,and i have replaced them under warrenty,on vehicles with as little as 20000 miles on them. a failed water pump can cause the overheating,,a stuck thermostat,can cause overheating,also a partially clogged radiator can cause this problem,but diagnosis should be done by a reputable shop. one last problem that can cause the overheating,is blown headgaskets,or a cracked head,an exsperienced technician can detect this by performing a hydrocarbon test on your coolant system. also you said your temperature gauge is not working? have a technician check the temp gauge sending unit,,it sounds like it needs replacement. i know car troubles are hard to swallow this close to CHRISTMAS,but get the vehicle to a shop asap,driving the vehicle while its overheating can cause perminent engine damage. i hope this information helps you
- Q: Variable flow variable frequency water pump how to adjust the flow?
- Flow plus transmitter control
- Q: i was coming home from from work and my jeep thew the serpenteen belt and my water pump is the only pulley not moving good like the rest and is leaking coolent. and people with just dump **** to say dont comment on this
- With either engine your jeep cherokee would have a 2.5 or 4.0. Both have the same pump, and the 2.5 would be easier because you would have more space from the smaller engine. But there not hard to replace. A repair manual would be help full if you have never replaced a water pump before.
- 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: Im considering installing an electric water pump in my car and i dont know much about electric water pumps yet so if you could tolerate a couple of dumb questions....? are electric water pumps reliable enough to be put into a daily driver (i just used the meziere name as an example, its the only name i am familiar with in electric water pumps)? i realise what the engine is basically done if the water pump goes.... could a change this small ever show up on either mpg or hp readings for a 200hp v6? finally, if the electric water pump just isnt worth the reliability risk, would a water pump underdrive pully do (almost) the same job of freeing work from the engine without putting the motor in harms way? thanks!
- I personally would not use an electric water pump on a street car. But ive seen them last pretty long on some cars. You can underdrive the pump but Im pretty sure the HP benefit of the electric pump is better. Meziere makes good quality electric pumps. If your going to go electric, go with Meziere.
- Q: How important is a torque wrench,if so what is the proper fp torque for pump/pulley ?
- It shouldn't be that critical for water pump bolts. It is extremely important for something like engine head bolts because of the extreme pressures inside the cylinders. Just refrain from over-tightening. I've replaced a number of water pumps and have never used a torque wrench.
- Q: I have a 1999 Chevy Cavalier Z24 2.4 engine and the water pump needs replaced how much would this cost me to take to a garage to have fixed?
- good okorder and see what is up with the price. The estimator sectrion may be able to give some idea of what a water pump sells for and the labor costs. One major problem with all of the front engine front wheel drive cars is the cost of replacing a water pump can be 2 to 4 times as much in labor as the front engine rear wheel drive vehicles of the 70a and 80s for example my suburban was a total of 200 dollars not so with the cavalier The water pump itself was not too bad but the labor getting to it sucks. 104 to 199 dollars for a waterpump and 627 to 800 dollars for the labor could bring you a bill for 732 to 999 dollars lets hope its the cheaper of the estimates
- Q: I need a new timing belt and I'm getting that done soon, but my mechanic says that water pumps are usually replaced along with the timing belt at the same time. Does it really need replaced?
- yep replace at the same time better safe than sorry it'll cost more if it leaks later and you need to replace it
