I just installed a new radiator and thermostat in my truck. The cooling system was flushed before I pulled the old one out. Would it be OK to run tap water through the system to test for leaks than draining it before filling it with anti-freeze?

This is my first radiator install. Hopefully the last.

Thanks.
