QJ Serise Submersible Centrifugal Water Pumps With Good Quality




Q:As a fact; I must remove the timing belt in order to remove both camshaft sprockets,then the metal timing belt cover which cover partially the water pump.My main question: Do I have to lift the engine and remove the two water pump studs- Which normally holding the right engine mounting.And where I can rent ,or buy a camshaft locking tool with low price
You can just jack up the motor from the oil pan with a floor jack with a piece of wood instead of removing the studs, just needs to go up a inch to get the bracket and water pump off.
Q:What do I get to bring a portAble water conection? Like as in bring a hose with you I gess? It's confusing how I described it but I just wanna use a garden hose so I can wash cars from my truck. Sorry it's hard to describe
A portable water pump. They come in a variety of sizes depending on your needs. A friend of mine runs a window cleaning service from the back of his truck. I don't know what size pump he has but I do know he also has a permanent water tank fitted as well as all the other fittings accoutrements for the job.
Q:I put the new water pump in and the metal tube that goes to the heater hose it is hitting the wheel that holds the 3 belts that goes onto the water pump. why is it doing that. got the right pump. I have a 1986 firebird V6. any ideas?
it quite is not any longer trouble-free to respond to given the coaching given. what form of motor vehicle ? in the experience that your vehicle has a waterpump this is grew to become by the timing belt, particular the save might have tousled on the cam timing as they re-assembled after setting up the pump. what's inflicting the click sound ? this is an inclination belt or any of one hundred issues. the place do you hear the sound coming from ?
Q:Our CRN series pumps used in the 414V 480V 60Hz 60Hz power supply, what would be the effect? Is not the head can be reduced, there is no water pump and lift what voltage relationship?
This is the world's Grundfos pump, if the pump itself support work under the 414V if it didn't need to worry about traffic and Yang Cheng, if the pump does not support the long time operation of the pump must lift and flow impact, and the multi-stage pump if it is Gao Yangcheng in the use of low lift it is also easy to burn the motor,
Q:I have a 2002 honda civic with 85k miles the dealer says the timing belt should be replaced. But with the water pump timing belt tensioner also have to be replaced???
The engine in your car makes the difference the 1.7 has a water pump driven by the timing belt and the 2.0 has an external water pump driven by the serpentine belt so find out what you have but if it is the 1.7 just do it.
Q:There is a loud squeecking noise coming from the water pump and the serpentime belt isnt loose!I dont know how long it would take a mechanic to do the job?
Spray some water on the belt while it's schreeching to rule the belt out. They often make noise, even when tight.
Q:I need instructions
....and we would need a make/model/year, and engine type. There's no set instructions for all cars!!!!
Q:I will be replacing my timing belt soon. The dealer is suggesting that I also replace the water pump. Is that really necessary? When do water pumps normally go out?
Nearly all engines with timing belt driven water pumps sholuld have BOTH replaced along with new rollers at certain intervals. It is an ACCEPTED from of preventative maintenance. ON many engines, the TIMING belt prevents valve damage, and the water pump bearings are used as another roller in the timing event. YOu are ALWQAYS better of by replacing ALL things involved, and by usingg ONLY the factory parts or factory timing betl KIT. ALso you should use ONLY the factory coolant type, as it will prevent further cooling system degradation over time. There is NO such thing as a universal coolant. WHAT KIND OF CAR IS THIS?? year, make,model and country of origin?
Q:i have a 1960 ford f100 and i was wondering if its better to have an electric water pump or mechanical. ive heard mechanical is worse because at low rpms it doesnt put as much water into the motor but i wasnt sure how true that was. What was is better so that my truck doesnt overheat? and how much better is one over the other if electric will just be a little better is it even worth using? also will i need to change anything on my motor to be able to put an electric water pump on it or will it just bolt on like the mechanical one does
Well your mechanical water pump is more than sufficient to pump water through your engine even at low rpms. Whether you have a electric or mechanical your can't pump more water though your engine than what your thermostat will allow you to. The advantage that i can see over electric would be the extra horse power you might get over having your mechanical
Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
