Q:Do I need to change the water pump if I replace the timing belt ? and does the water pump connect with the timing belt ? if the water pump goes out will it bend the rods ?
i would get out of that thing they are nothing but trouble always! a have a freind got a nice chevy ,never been happier?
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:My well is 58 meters deep, the water level is 20 meters, the water level has not been measured. What's the maximum water pump I should choose?
First, determine the size of the electrical well and then the depth. Is it water injection or pumping?The pressure of water injection pump is much higher. If you pump water, it depends on how much water you need every hour Plus you enter the water depth of +10 meters, you can basically a good selection.
Q:And if it needs to be replaced, does that spell trouble for a car? I see a car I might like to buy, but the ad says that the water pump needs to be replaced. Someone please enlighten me. Thanks.
a water pump circulates the coolant thru the radiator to keep the engine cool. Some are outside of the engine and fairly easy to replace. others are stuck in at rediculous places and require special tools and dynamite to remove. It better be an awful nice car but at least the seller was honest about it so maybe he would be honest about th rest of the car. Its not a BIG expense but maybe you sould get an estimate so you know and can add that to what you will have to pay for the car. and get it fixed right away so you don't have to replace the engine too.
Q:I have a cabin cruiser and I recently took it out of storage and had it de winterized. Now everything seems to work except for the fresh water pump for the sink, shower and toilet. Does this type of pump need to be primed? If so how do you prime it? Thank you for the help.
most likely the pressure switch is stuck/corroded. this is a common problem with on demand type pumps.try tapping on the pressure switch to see if it will work.if the pump is installed properly,the motor should be at the top and the pump and switch will be at the bottom.i consider these pumps disposable. expect to replace it every couple of years.
Q:I am leaking antifreeze, but only when the car is sitting after it has been running for a while, and its quite frustrating..it's coming around where the hoses are, I just got the thermostat/thermostat housing replaced, and also the heater hose and it seems to be coming from the same general area AS those...My car doesn't leak all the time it seems, so I'm not sure what this could mean. It has not over heated, my ac isn't also working at all.I have taken it back to the mechanic two times in the last 2 days and they cannot determine it's having a leak or not..which is quite ridiculous!! It seems to them that they think I'm crazy or something, I just don't like to see antifreeze underneath my car, I mean who does? Does this sound like a water pump? Where exactly is the waterpump located?
i would say its where you had ur stuff replaced before. They might not have the clamp on hosestight enough. Or the housing isnt tightened enough and or they overfilled especially with them not tightening it all up. Seen it happen alot. And it happens because they dont recheck for any leaks after the work is dne and make sure everything is all nice and tidey before they give it back to customer. If it was ur pump u would overheat and not have enough pressure to leak in any hoses or housings but only ur pump weep holes is where it would leak...
Q:i want to change the water pump on my on a 70 hp (70C) nissan outboard motor and i never pulled a lower unit, not sure what to expect thanks for any help
CW pushes water up into the motor housing.
Q:the impeller on my calpump pw1200 water pump will not turn. what is the problem? and how do you fix it
CLR soak. Remove the calcium and lime from the tap water use. I would use a 50/50 solution in the inlet and give it 30 min then plug it back in with the in and out in a bucket with the 50/50 mix until it runs like new.
Q:I live in a residential/country area, and I have a well pump down cellar. I notice that, even if I am not using any water, nothing is running (toilet, etc) it tends to cycle on and off every hour or so. The pressure is always good, so that's not an issue. I am just wondering....is it normal for it to do this?
No problems. It just means that the check valve in the pump is leaking off slightly and the pressure is dropping down to kick the relay in. As long as it doesn't do it every few minutes when water isn't being used, you have nothing to worry about. If you have a facet with a drip, it will do the same thing.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
It's better not to start directly. It's a great test for your motor and contactor. Do a star three start, conditional on doing a star three plus autotransformer start, reducing the starting current. Reduce future maintenance costs. Since do not think about every day to do pump repair.
