the motor should still be ok. get a new thermostat and either have your radiator cleaned out, or replace it

I prefer the "rod out" or replacement. It might be best to just replace the radiator

depending on how old it is. What does it look like inside (when you take off the

cap)?

You slack buggers,



Using the formula, that would make the temp range about 185-203F.

Which means yes, your running in the right temp range.
