Q:2 pumps in parallel, lift the same, the pump head is not stacked; 2 pumps in series, the same flow, pump head is not superimposed?.

2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.

Q:How can I test to be sure my water pump is working before I go to the lake and burn up my motor. `72 65hp johnson. thank you.

You can also go to a marina and buy earmuffs that hook to a garden hose and fit over your water intake. As stated above just look for a stream of water coming out the back of the engine.

Q:Hi I just brought a chrysler sebring V6 that needs a water pump. I found a water pump on OKorder for only $30 and it only had 900 miles and it works great. Should I buy it?

Compare it against the price of a new pump. 1000miles isnt a lot for a waterpump, but can you be certain the car only did 1000miles? Waterpumps can last for 100,000 miles, but if a new waterpump is only $50 or $60, I would buy a new one.

Q:How can I be sure the water pump is the problem before spending $ on repairs. 97 civic overheating.?

You check the water pump by looking at it! Underneath the input shaft of the water-pump is a small weep-hole that leaks coolant if the bearings and seals are shot. If there's no leak in that location absolutely nothing is wrong with the water-pump regardless what you read above. Change the thermostat with a factory OEM unit. Remove the radiator cap when the motor is cold. If the radiator return valve on the bottom is brown and dirty the entire cooling system should be drained, flushed and cleaned. The heater core and radiator cross fins are probably plugged full because of years of not changing the coolant. Is the electric fan working? When the motor starts to overheat, wrap a gloved hand around the top radiator hose. If it's barely warm the thermostat is sticking closed. If it's hot the radiator and entire cooling system needs to be cleaned with Prestone Super Radiator Cleaner.

Q:Hello, i have a 1987 volkswagen cabriolet that i purchased earlier this year. So far its been a pain in the butt. Recently i noticed it overheats real quick, but it didnt use to. then i noticed the coolant/antifreeze was being used up like no other! I discovered, after being parked at work, that it was leaking.it leaks basically anything i put in there now!! it leaks from the water pump housing,.,.... at least thats what the internet said it was.. its leaking from the end of the hose that connects to the engine... (the hose that comes from the coolant reservoir.)What do i do? I dont feel any cracks? does this part crack? is it an o-ring or somehting? I am really absolutely NOTHING ABOUT CARS. Please help!!

Water pumps have a seal to hold the water from leaking out the spinning shaft, and the seal always wears out about every 100,000 miles. It is probably this seal that is bad, because it is probably the original pump, and you replace the whole pump. You have to take the front belt cover off and remove the timing belt, so it is not a trivial job. Cost about $300, and takes about 2 hours. But any friend who understands timing belts can do it easily. No special tools or tricks involved, other than making sure the cam timing is correct. Once you take the 3 bolts holding the water pump housing off, you can easily tell if any hoses or clamps should also be replaced. Do the thermostat while you have it off anyway. It is only $5.

Q:Is it a must to change the entire water pump since only driplets of anti-freeze leak out over a 7day period from the bottom of the pump? Can i simply change the gasket and make it all better? Water pump is pumping and making no noise, vehicle isnt over heating.

your water weep hole is on bottom of water pump also.if its the water pump weep hole leaking.that signs of water pump shaft bearing is going bad.water pump needs replacing.

Q:I'm going on a week long hiking trip and need safe water. What brand and model of water filter/pump should i get? Whats good quality for a low price?

I like the MSR miniworks because it is reliable and easily serviceable. The downside is that it is heavy. If weight is an issue, I will either use bleach or Aquatabs to treat the water.

Q:How to install circulating water pump for cooling tower?

Water pump, cold water pump and hot water pump, the specific installation depends on the location of the cooling tower and the location of the heat exchanger, high cooling tower position, the need for hot water pump, heat exchanger position high.The cooling tower, cooling tower (Cooling tower), is using water as coolant, from a system to absorb heat emissions to the atmosphere, heat exchanged to produce steam, steam heat to volatile evaporation dissipation, convection and radiation heat transfer principle to disperse industrial waste heat or refrigeration and air conditioning to reduce evaporation cooling device therefore, in order to ensure the normal operation of the system, device as a barrel. The cooling tower can be divided into natural ventilation cooling tower and mechanical ventilation cooling tower according to its ventilation mode.

Q:my 98 expedition keeps over heating, i replaced the water pump, thermostat,coolant. it will be fine one minute then it overheats. weather im on the road or sitting at a light. i also replaced the fan clutch. thanks!

I would check the radiator first and if its not it then your looking at a bad head or head gasket if u have already replaced what u said u have

Q:my basement flooded and the water came in contact with the wiring on my water pump.Now the pump tries to turn on but shuts off without pumping any water.How do i get my pump pumping water again?
