Water Pump and Coolant
I am replacing my water pump and while Im at it some hoses. When I finish, I would like to make sure it does not leak before I add anti-freeze. So I thought of filling it with water for a pressure test, then draining and adding coolant.
Would there be any danger in this and for how long could I run it this way? No danger of a freeze here in Texas. Would tap water be ok for initial test or should I use distilled?
I was thinking of using motorcraft gold antifreeze, as I have read it has the proper sca. Any other suggestion on antifreeze would be appreciated.

After i did my head gaskets i ran water all summer. If they ended up leaking again i didnt want antifreeze in with my new bearings. Water is the more efficent at dissipating heat then a water/coolant mix. If you use distilled it can stay in there a long time but you may get some rust issues in a few months. But for testing tap water is ok.

Don't put anything in it and just pressure test it with a radiator pressure tester. Pump it up, go have coffee, come back if the pressure is the same your good.
If you don't have one you can borrow one from an auto parts store like Advance.

That's cool. Ive never seen one. I guess it has what pressure you need to pump to?
