Q: Weap seal is starting to leak and getting some noise from the water pump. These cars are not as easy as a 1969 Camaro to change the water pump. Can you please give me some guidance? Thx in advance.: is replacing the water pump on a 2000 the same as a 2001 chrystler 300 m

Q: Where is the water pump located on a 1993 mitsubishi eclipse with a 1.8 motor: it is belt driven pulley near the center of engine, unless mitsu made that one timing belt driven in which case you can't see it with-out dissassembling front part of engine.

Q: What does the pump lift mean?: The pump head is the height or length of the distance from the pump to the outlet

Q: I need instructions: need to know what type of car and motor size

Q: I installed a new water pump on a Cherokee straight-6 engine, the upper radiator hose is not heating up and the engine is starting to make a funny noise. The thermostat is new and was working fine before. The coolant reservoir is full and no more coolant will drain to radiator / engine. Anyone know why waterpump is not circulating coolant?: Did you prefill the radiator before you started it? Did you put the thermostat in upside down? After it cools, remove the radiator cap and fill the radiator with the engine idling.

Q: Today I see the saying that if your pipe diameter has been selected, then the pipe diameter on the pipe diameter should be smaller. I don't know why: In order to reduce the water outlet resistance of pump outlet.The statement should be: if your pump has been selected, then the outer outlet pipe caliber than the water pump outlet diameter one.

Q: Why can't sprinkler system and hydrant system share water pump in fire fighting system?: Why not share mainly because the two impurities contained in the water system: fire hydrant system requirements of different impurities in the water spray system requirements loose, but more stringent requirements, therefore, the former can be welded steel pipe, the latter must use galvanized pipe, the purpose is to prevent rust plug flow indicator or end of the spray head.

Q: Our watrer pump on our well will constantly prime itself when we use the water in our house.As you are running the tap the water will gain pressure on and off like someone is using another tap in the house. Any suggestions?THanks in advacne: How old is the Pump ? Could the Impeller be worn out ? Is there a replaceable filter ? Could it possibly be stopped up ? Are there any leaks in the pipe leading from the well ? Is there a way that you could measure the current being drawn by the pump, with an Amp Meter, to determine if it's pulling more Current than it should be ? Until these questions are answered, it's probably just going to be a guessing game.

Q: Would I notice a difference in driving if I changed my timing belt and water pump?: If your car is overheating then you might need to change your water pump. If the pump is making a bunch of noise, the bearings might be worn out in it too. The timing belt just keeps your overhead cam in time with the crankshaft - you should replace it at the intervals recommended by the manufacturer - especially if your engine is considered an 'interference' engine - meaning that if it jumps time the valves will hit the pistons. You won't notice any difference in performance with either component though. For performance, check your plugs, plug wires, air filter, run some fuel injector cleaner through your gas, and replace the fuel filter. Other performance related issues include - fuel pump failing or reduced compression (due to piston rings being worn out).

Q: After the pump has the control box, but also the power distribution box, the control box and the distribution box is not the same box?: This look at the specific situation, the water pump circuit is divided into power, power and control signal two parts,They can be placed in a larger cabinet, which is convenient for future inspection and repair.There is power and signal is separated from the general distribution box and put some air contactors, frequency converter etc.,There are some buttons, lights, etc. in the control box.
