Noisy afterrun coolant pump

[David Eaton]

i have had success in r&r'ing these things.  check price and availability of
the new item 1st though (my re-conditioned one is now my spare).  common
failure mode is coolant seepage, or water ingress past the motor seals.
relatively straight-forward to disassemble and re-condition.

		The rotor in your pump might be seized. See archives for the
discussion
		of this topic. The pump has a magnetic coupling between the
motor and
		the rotor. This magnet attracts all metal and rust particles
which flow
		with the coolant up to the point when the rotor seizes. I'd
check if
		your pump actually generates any coolant flow.
