Let me add this little nugget.

You bought the car used. You have no idea of the condition of any fluids or when they were changed last. Things to look at, oil, coolant, trans fluid, brake fluid and last diff fluid (this crap seems to last forever, must be the smell that keeps it good). At minimum at least check the coolant.

Once again the gauge on the dash is not linear or very accurate. You're guessing at 200.

It's never a bad idea to look things over and inspect them. Pulling the rad gives you a chance to check your hose condition, rad for for leaks or possible problem spots, clean the rad and gives you areal good opportunity to learn on a relatively simple project.
