Hi I have a 93 mercury villager mechanic replaced water pump and belts but dnt think thy timed it wen I picked it was thn wen I brought it it first gt hot again then was driving engine shut down
Before entirely blaming the village mechanic I would guess the water pump was probably not the only thing wrong and either the failing water pump caused another fault, made another existing fault worse or perhaps wasn't the original fault causing the symptoms.
Water pumps are very reliable and mostly only two things go wrong; either the bearing begins to fail and becomes noisy or the seal wears out and they begin to leak. Mostly these two things happen together but neither prevents the pump from pumping as long as the coolant level is kept topped up and so overheating and other symptoms cannot directly be caused by the water pump.
There have been a few isolated cases of the pump impeller falling off but that is very rare and something I have seen only once in forty years.
If a leaky pump caused the coolant level to fall significantly the engine could overheat and it is that overheating that tends to cause subsequent symptoms that need further diagnosis.
Overheating can shift large quantities of sediment from the engine block which can block a radiator. Overheating can damage thermostats, sensors and cylinder head gaskets. A damaged cylinder head gasket can soon cause lots more symptoms and eventually write-off and engine.
It is possible your village mechanic didn't time the engine correctly but on the face of things all he is guilty of is not testing the car thoroughly enough after his repair. Often this is caused by a lack of good communication between the owner and repairer.
