Q:LSvtec Oil and Water Pump Question?
you need the GSR/Type-R water pump. This is one of the major causes of LS/VTEC failure. The GSR/Type-R has 22 teeth while the LS/GS has 19 teeth. The extra teeth cause it to spin faster pushing more water through the system. Any time you change something related that uses the timing belt, I ALWAYS install a new timing belt, and tensioner. That way there are no worries later.
Q:I think our water pump over heated, will it go back to normal after it cools down? It wasnt turning off?!?! ?
I assume you have a water well pump. The experience I have had, is it will come back on once the thermal safety switch cools down. However, I think you still have work here to do because each time this happens, you are shortening the life of your pump. First you need to determine why it ran hot to begin with. Could be lots of reasons, but just to name a few. -Is your water tank in good shape, with the correct air pressure? -Is the tank waterlogged, too old or leaking? -Any leaks in the service in or to the house? -Is your contact switch working properly, clean contacts, good wire, good connections, breaker etc.? -Is there water running somewhere your not aware of? -Last but not least, the check valve and foot valve leading to the well could also be defective. Just my opinion, I hope this helps to get you thinking. Good luck; flip;
Q:water pump leaking antifreeze?
Unfortunately, this usually requires a new pump. It's possible (but unlikely) that the gasket is leaking - more likely, the seal around the pulley shaft is the problem. Replacement is the only option. Usually, this is done at the same time as the timing belt - has this been done yet? If it was done before you got the car, its possible they tried to save a few bucks by skipping the water pump. This is usually a bad move - the pump almost always wears out at about the same time - but it is cheaper, if they were planning on getting rid of the car soon. And since one usually needs to be removed to access the other...you get the idea. Good luck!
Q:how to tell if water pump bearing is bad?
No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!
Q:Does this water pump exist?
Yes but you need a hydrological manual secretor to recreate the same power as with electricity.
Q:should I buy a used water pump with under 1000 miles?
Yes. Most salvage yards will give a 30 day warranty. It's worth a try. Make sure when you replace the water pump you also replace the timing belt. The reason is, in order to get to the water pump the parts all have to be removed so you might as well replace it when the mechanic is in there. Your timing belt could go out next week and you'd have to pay all of the labor again.
Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
Variable frequency water pump refers to the motor, variable frequency pump should be driven by variable frequency motor pumpFrequency conversion, that is, adjustable frequency, frequency conversion motor is able to adjust the speed, adjust the flow, to achieve the purpose of energy saving, but also start small current, maintenance advantages of small workload
Q:How to change a water pump on a 1991 Mercury Topaz?
Water Pump RemovalRemoval: Disconnect battery ground cable and drain coolant from engine. Loosen water pump idler pulley bolt and remove belt from water pump pulley. Remove water pump inlet tube. Remove three water pump retaining bolts and water pump, Fig. 16. Installation: Clean both gasket mating surfaces on water pump and cylinder block. Install three water pump retaining bolts and tighten to 20-30 N-m (15-22 ft-lbs). Connect water pump inlet tube on water pump. Install water pump belt on pulley and adjust tension to specification. Connect battery ground cable. Replace engine coolant. Operate engine until normal operating temperature is reached. Check for leaks and recheck coolant level. Couldn't get the picure but this should help, the pump is located on the backside of the engine, just be carefull, this engine is really easy to get the pulley on backwards then the belt won't line up right.
Q:How do I quiet a noisy water well pump?
It sounds to me like water hammer. There are a few ways to address it, probably the easiest is to add an expansion tank. To find out, try connecting a garden hose somewhere in the system, preferably a cold water pipe. Drain all the water from the hose and put a nozzle or plug on the end so the air can't escape, then turn the valve on. The air in the hose will act as a cushion and, if water hammer is the problem, you won't hear it while the hose is connected. That is not a permanent solution, just a simple test that might give you an answer. Good luck
Q:Radiator hose or Water pump?
2001 is not very old! If you can't see coolant leaking from some point when the engine is warm (and you WILL see it, and be able to track where it is coming from, if from a hose, a pipe, the radiator, or the pump, or a welch plug or some particular place in the engine bay), you could have a cracked head or block, or a blown head gasket. Another simpler possibility is the thermostat has gone bad. If the leak is from a head gasket or a crack inside the engine, a pressure test can be placed on the whole system to establish this. There could also be signs of coolant in the oil.
