Overheating

[tlzimmerman]

If it were my truck, no more of a job it is to put in or take out a thermostat I would put it back in so the truck ran at the correct temp. Same goes with coolant, they are designed to run coolant, not water....I have always been told straight water doesn't pull heat away as efficiently as coolant, and it also lowers your boiling point to run straight water.

I don't suppose it would kill it to run on water, but if you can beg borrow or steal some buckets to save your coolant you should be able to reuse it just fine.
