Q:Was my timing belt or water pump replaced incorrectly?
12 hours on a civic DX. I am a honda mechanic and I will say that this job only takes 2 hours, 4 hours if your slow and never done it before. Mind you this includes timing belt, water pump, cam seal, crankshaft seal, serpentine belts, valve cover gasket, spark plugs if needed, Honda coolant, and valve adjustment. If you are 1 tooth off on timing your Honda will run, but it will run very rough. Sounds to me like they may have the timing 1 tooth off, 2 teeth off and the car just wont run and if it does it will barely run. This car needs to be taken back and everything i told you should have been done and done properly. What probably happened is the dealer let an apprentice work on the car, since this civic is the easiest to do a timing belt on. However its still their fault that it was not done properly.
Q:radiator problems.....or a broken water pump?
I'd say the most likely thing is the thermostat. It is the most common cause of overheating when there is plenty of water in the system. As you already know, the radiator can leak and make it get hot. You can add water and it will stay cool for awhile, until the water leaks out again. The same can be true of a leaky water pump, heater core, or hose. If there is no leak, or no obvious leak, and the system seems to have enough water in it, but it still gets hot it is more than likely the thermostat. The thermostat blocks off the water from the radiator until the engine warms up. It can be damaged by getting too hot (like when you had a bad radiator) and fail soon after. Other possibilities are an electric cooling fan that isn't working, or a blown head gasket.
Q:how to repaira water pump?
If you have to ask the question you don't have the skills to do it. You could see if there's anyone in your area who rebuilds motors and ask them to look at it, but if it smoked it's probably dead. If you want to try some simple things, take it apart, dry it out and put it back together and see if it works. If does, see if you can see where the water was leaking from and see if you can seal it back up.
Q:How many kilometres should a water pump be changed on a toyota hiace 5l engine?
Water pumps get changed when they start leaking or the impeller breaks loose. Not normally changed in a preventive maintenance program.
Q:What is the purpose of providing recirculation line & balance leak off line for a boiler feed water pump?
The feed pumps for most power plants are multistage centrifugal pumps. They have a minimum flow requirement or the balancing forces of the various impellers are lost and the pump is damaged. A recirculation line permits a minimum flow to be maintained at all times. It goes back to the deaerator so the boiler feedwater is not lost. Note: many of these pumps have the recycle automated so it is only in operation at very low flow rates. The leak off from the balancing line is recycled for the same reason.
Q:Does exercise affect the amount of salts and water pumped out of the loop of henle?
During exercise the amount of fluid passed through the LOH is increased due to the increase in blood pressure and cardiac output. The actual balance of salt and water is regulated through a different mechanism. Chemoreceptors and baroreceptors in major vessels keep track of the relative concentrations of salts and pressures in the blood vessels and direct the release of hormones that affect kidney function. For example, while exercising excessive sweating may increase the concentration of salt in the blood. To counter this anti-diuretic hormone is released to increase the amount of water reabsorbed by the kidneys. During exercise, the amount of urine produced is lessened because the water balance is used to produce sweat to cool the body. In response to the loss of water, the concentration of salt in the blood increases which triggers the thirst impulse in order to dilute to blood to normal concentrations.
Q:Variable flow variable frequency water pump how to adjust the flow?
Flow plus transmitter control
Q:is it safe to drive without a water pump?
you can drive 10 to 20 minutes with out one and then walk the rest of the way
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Low inlet and outlet
Q:Timing Belt & Water Pump?
Some cars have different designs. The water pump on my 96 Century could have been done in a matter of minutes. Where as some are much deeper in the engine. Usually, to change a water pump like this is pretty much one more step than changing the timing belt. This is why it's usually a good idea to do them both at once.
