Q:how to remove rear bolt from water pump?
Sometimes there are holes in the pulley and you can rotate it until the hole gives you access to the bolt. If there are no such holes, then you will probably have to remove the pulley. The pulley may be fastened with one, four, or zero bolts. If there are bolts for the pulley, remove them and proceed with common sense and use a puller if necessary. If there are zero bolts holding the pulley to the water pump, then it is pressed on and you will need to remove it with a specialty tool called a pulley puller which you can get as a loaner or cheap rental at many auto parts stores. The pulley must also be reinstalled with a pulley installer, also available as a loaner or cheap rental. Are you replacing the water pump or just removing it to do other work? If you look at a new one and it doesn't come with a pulley on it, then you know that the pulley must be removed to go on the new pump no matter what.
Q:bmw 2745i water pump?
Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
Q:Water pump belongs to power equipment or mechanical equipment?
Ownership of mechanical power equipment in assets
Q:Toyota 2006 Sienna, Timing Belt, Water Pump, Drive Belt & Trans Pan Gasket replacement?
not sure about the timing belt but water pump seems expensive, so does the drive belt but the transmission pan gasket is a rip off. it should not be $350, those are not that hard to replace. dont go to a dealer for all this, try other mechanics dealer is out to get your money but they will do a good job. other mechanics will do it cheaper but a poor job. if your car has 80K you can possibly go up to 100K, I mean timing belt does need to be checked around there, is your water pump leaking? if not then your wasting money, pan gasket is there a pink oil leak, if so then probably its time for a new pan gasket...
Q:replaced my water pump?
Sounds like foot valve to me is not seating properly and you wouldn't hear the leak under water level guess your tank has enough air gap top of tank and water level if that is insufficient pump will also short cycle should have a valve stem with internal bladder inside of tank if it is similar to my old tank. Your pressure is same as my old one and it was fine.

Q:Water pump make screech noise?
You must have a surface mounted well pump also called a jet pump or you wouldn't hear a noise from a submirsable which is at the bottom of the well. Check where the motor hooks onto the pump itself to see if there are any small oil fittings. I doubt that there are, but it can't hurt to look. If you find any use 3M or similar oil to lubricate the bearings. If the house has been vacant for awhile those bearings might be rusty from sitting, and may stop swealing on their own as you use the pump and the shaft/bearings may grind the surface rust off and stop the noise. If they don't you will have to call a service company to evaluate the problem. Here is part of jet pump potential maintainence issues: Perform necessary pump maintenance: some water pumps require inspection and replacement of internal parts such as bearings or impellers as often as after just four or five years of use. While it may be possible to ignore this maintenance for a while, the effect may be to so wear the pump or pump motor parts that complete pump or pump motor replacement are necessary.
Q:Bad water pump diagnose?
A leaky radiator could also be the cause of leaking coolant. Sometimes waterpumps rattle as they're dying.
