Hi Paul,
You may want to consider changing out the water pump too, while you're
in there. I know the old saying, if it ain't broke..don't fix it, but my
experience was that I changed my water pump and checked my timing belt
and tensioner, then drove the car for weeks, only to discover an oil
leak at the cam seal....so had to go back in to change out all the
seals. So my new saying is(on cars with an unknown history), if in
doubt, swap it out. It's the old, measure twice, cut once theory. It's
an easy area to work on, but why do double the work! Just my $.02. Good
luck.
