I've got a 1988 Honda Civic that a few days started making a strange noise.
It's a loud rattle..very mechanical sounding....coming from the engine. It is
definitely not the heat shield or something like that. Being somewhat handy,
I first tried to diagnose this. The engine seems to run normally but we
haven't driven any distance since the noise started. Long story short.....it
is dripping antifreeze from around the main shaft (where the belts are). This
is almost certainly a water pump failure, yes? The noise is getting
substantial now and I'm wondering if, even the car can be driven, should I tow
it to the dealer for the replacement of the pump and timing belt? I fear for
the TB en route if I drive.

Replacing the water pump is also essentially replacing the TB too. Is this a
job I might undertake? I have many tools and have done various car repairs
like alternator, brakes, valves, etc. This job seems much bigger but possibly
do-able. Thoughts?
Thanks
