'morning listees,
Anybody have an opinion as to whether a used
water pump with 100,000 miles on it, tho working,
would be worthwhile to keep on hand as a backup?

My repair funds are nill at moment & I am considering
a used one offered for $20.
I understand that there is a lot of labor involved in
replacing a water pump--would this mean that installing
a used on with 1000,000 miles would be a false economy?

Advice appreciated,
Phaedra
