Yes, a water pump can make a knocking noise, which may indicate several issues. Common causes include air trapped in the pump, loose mounting, or wear and tear on internal components. It's important to diagnose the source of the noise promptly, as it could lead to more significant problems if not addressed. Regular maintenance can help prevent such noises and ensure the pump operates smoothly.
my 1995 BMW 325i is making a knocking noise after i replace the water pump
Bad fuel pump, loose fuel pump, loose baffle or foreign matter in the tank.
There could be loosened internal mounts (connecting rods, pistons, pins, crankshafts or other related parts) in the compressor causing the banging or knocking noise. A simple call to a technician should resolve the issue.
If the noise is coming from where the water pump is, it is a good chance the it is actually the timing belt tensioner. These things are notorious for making awful noises when they are beginning to go out and will get worse and worse. The same engines are in an Isuzu Rodeo with the exact same problem.
check your water pump,check all your pulleys make sure their bearings are ok
Activation.
If the oil pump has failed...yes definitly. your crank has been starved for oil and has worn or spun the bearings. time for a lower engine rebuild and new oil pump.
It is possible that the bearings are going bad on the water pump but you are going to have to listen to where the noise is coming from, whether it is inside the engine ( rod knock or oil pressure issues ) or outside (pump bearings or pulley issues).I lean toward internal wear or damage to the engine since the noise goes away when it warms up which indicates that when good oil circulation is present the problem goes away, bad bearings in a water pump will always make noise until they are repaired.
After bleeding the power steering the pump may make a noise because there isn't enough power steering fluid in it.
If the fuel pump is bad it will just quit pumping gas, the electric fuel pump always makes a little noise when running.
there is probably something in the pool that got into the pump
It will normally start with a leak at the pump. If the impeller breaks you will hear a rattling noise at the pump.It will normally start with a leak at the pump. If the impeller breaks you will hear a rattling noise at the pump.
