What coolant should I use?

Hello everybody

I'm looking to do a coolant flush in my 1966 C10 with a 305 engine.
I'm not sure what coolant is in there now so I'm going to flush it out, what type should I use to replace the existing coolant?
Thanks

I'm in Cali also and I have always used Prestone 50/50 and have never had a problem. If you decide to dilute it with water you will want to use distilled water.

Cheap regular Prestone is fine.
