Mike, sorry to hear about the water pump and steaming breakdown.
Not to emphasize any bad news, but I am with Dennis on the potential for
engine damage.
I actually had 2 steamy breakdown events ('89 2.1):
- water pump blew on the freeway, I limped the van a few hundred yards to
the next exit ramp (narrow walled trench freeway in the city, kids on board,
didn't want to stop in a bad place)
- a couple years later that firewall multi-connector plastic fitting blew
(same deal, buzzers, lights, adrenaline, etc) right on an exit ramp. There
was literally a huge chunk of the plastic that went missing (by the way
gowesty has metal replacements for this thing which I then installed).
A year later, can't pass smog test: root cause, burnt exhaust valve. Can't
say for sure, but it is quite probable that these steamy events were the
cause, only because in both cases I ran the van for 30-60 seconds more to
get to a place where I was more comfortable to stop. Maybe if I had stopped
right away I could have avoided an expensive head replacement.
