Re: Loss of coolant....can I damage water pump with engine startup???
Your biggest risk is baking out the valve seals. They are up top and
when the temp hits red, you are cooking them really fast. This can turn
a nice engine into a smoker.
See if you can fill it and run it with the rad cap off. If it will stay
stable then maybe you can make it that way, but....
It really isn't a good thing to chance, when a pump bearing blows out,
the fan or pulley can even come spinning off.

No - just use plain water - it's all going to puke out anyway. You
aren't helping the engine and you are harming the environment.
Leave the cap loose (but not off) so pressure won't build up in the
system. If it is really dumping out, stop every couple of minutes to
top up. With the cap loose you don't have to worry about a geiser out
the top. I don't think the water temp will get high enough to worry
about pouring cold water in a hot rad - it's probably junk anyway.
Pick a time of day when there is little traffic so you don't waste
time sitting in line at the intersections.
My 2 cents.

Re: Loss of coolant....can I damage water pump with engine startup???
Doesn't anyone use a tow strap anymore? If you can keep water in it, your
ok. If you can run it without a cap,I would check water about every 1/2 mile
or so. Overheating the cyls and head will cost a lot more than a tow.
