Had to solder the radiator up today

[Jerry]

While I'm messing about trying cure my ailing cooling system is it OK to use plain water instead of the green stuff?

I'll probably need to drain it down a few times before I've cured all the problems so I'd like to use water so I can just dump it on the ground.

In the haynes manual it says not to use plain Jane water in a pressurized system because it'll boil where the green stuff won't :hmm:

The boiling point of water at sea level is 212 degrees F. That's about where the Jeep engines run. The boiling point for 50/50 glycol mix is up around 250 or 260 degrees. Plus, plain water in the engine will start things rusting inside your block before you can blink. Save your coolant when you drain it, strain it through cheesecloth, and re-use it.

Thank for the advice, I'll use coolant :thumbsup:
