I don't know how much good it does but awhile back I started using the
lubricating additive for the water pump (engine at 142K) that is added to
the existing water/coolant mix.  While I feel that good/fresh coolant should
be sufficient, I just got the urge to buy some additional insurance.
Comments? Dumb or not?
