Speak in shorthand. Don't expect much help. 160 too cold.
Now, if you can manage to put a complete sentence or two together and tell us what year vehicle we're talking about, and what sort of cooling system it has, somebody might be able to make some intelligent suggestions. If you're running a modern cooling system with a 15 pound pressure cap, the coolant temperature can go to approximately 250 degrees without boiling over. If you happen to have an older pickup with a zero or 4 pound system, the temperature doesn't need to go above about 200 or so.
Modern V8's are designed to run between 195 and 220 degrees so the parts can heat up and expand to get proper running clearances. Unless the radiator is boiling large quantities of coolant out of the overflow pipe, IT'S NOT OVERHEATING!
