how much would they charge me to change a water pump on my 1999 cadillac deville
They always change the water pump and timing belt together while the engine is apart. Your 1999 is probably due for both things if they have not been done. I just had mine done on a Toyota Camry. It cost a thousand dollars. Remember that these two things NEED to be changed every so often..if either the water pump, or timing belt go while you are driving..your car will die right there on the freeway...even if you are going 80 MPH.
Okay so we have a water pump outside instead of city water. A few days ago we noticed that it would turn off like always once the tank was full but then just would never turn back on. It was odd to us since it would always turn on and off at appropriate times. Now its on maybe 10 seconds and it shuts off. I took off one of the clear hoses it has and notices a green ooze inside it. I cleaned out the ooze and tapped some of the pipes in hopes of some more of it coming out. Since we have had a leak there is green stuff which i am guessing is lime, on the side of the tank. I'm also guessing this must bee the green ooze. What should I do? Now there is no water whatsoever being pumped and the time it does turn on very little water passes through. To me it sounds like something is blocking the pipes but if I pay hundreds for someone to come replace the pipes and check out the motor I dont want to end up with this problem again. If anyone has any information as to helping me I would so greatly appreciate it.
do you have shallow or deep well its the middle of summer the well could be dry you might have lost your prime on your pump there will be a bolt for priming take bolt out pour water in to hole untill full restart pump if pump doesnt fill up you might a stuck foot valve.
I would like a website that has pictures but any info would be helpful...
if you have problem with overheating you have to upgrade your radiator and upgrade your fans too installing an external waterpump you have to install it on your passenger side like many drag cars have
they say a water pump going bad is supposed to weep out of that hole....Yet I see that a new water pump kit has two gaskettes.some o rings....is it likely that it can leak from these sources and still not come out the weep hole?They talk about berring that could go bad or seals gone bad...does this occure in the area that gets inserted into the engine( the turbine portion of the pump)if you had to guess..where is the most likely area for a water pump to fail...if seems like I have wetness off to the left( back toward the firewall) and less off to the right( front of the car)..more off the left..it is very subtile off the right.I don't see anything coming out of the weep hole..BUT the weephole is directly on top( dead center)and back towards the engine in this model. I have the car jacked up on the passengers side/next to the wheel wellso the fluid is most likely to flow backwards toward the drivers side.
Yes it's possible one of the gaskets is bad,but if you're going thru the work of replacing the gasket you may as well replace the water pump,unless it's a new unit already
What is the 10KV pump unit?
The 10KV pump unit, driven by a high voltage motor, is used for drawing water!
what is NPSH for the water pump. Can you anyone explain in details? How can it calculate?
Net Positive Suction Head Equation
I went to have my car inspected for a leak at a friendly garage I know. They said I need a new water pump and in the mean time just keep the levels always checked and filled. Is it safe to drive for a while or can the pump totally fail and overheat the engine. As far as I know it's just leaking at this stage, the pulley and belts are fine.
Post basics: make, model, miles, yr, engine type. It's more likely to fail suddenly on a '95 Neon w/ 200k mi, than a 2010 Honda w/ 10k.
Give me a general intro. about submersible water pumps.
A water pump can have all the works above the water, pulling by suction and pushed by atmospheric pressure to a maximum of about 33 feet. Or it can have the motor above water and the lifting mechanism below with a long rod connecting (like an oil well with the donkey engine on the surface), but a bunch of weight and friction. Or it can be waterproofed and the motor and pump lowered down the drilled shaft on a plastic pipe with an electrical cord along side and push the water up. The last is a submersable. Similarly sump pumps and recirculating pumps where the cord, motor, and pump are under the liquid.
