I have just finished flushing the cooling system and replacing the coolant.
Of course, when I started the engine the water pump began whining for the
first time!  I was advised by a friend in the recycling business - who
refused to sell me a used pump - to buy a dealer's pump and not an
aftermarket product.  He says the system is too stressed to rely on some
unknown manufacturer producing a pump that can move the coolant 24 ft from
the engine to the rad and back.  What is the experience out there?
