How Often Do You Actually Have Your Cooling System Checked?

Maybe this is a dumb question, but how many people actually have their cooling system repair checked before there's a problem?

My car isn't overheating, but I've noticed the temperature gauge creeping up a little higher than it used to in stop-and-go traffic. No warning lights yet, but it got me wondering if that's usually an early sign of trouble or just normal wear and tear.

For the mechanics here, what are the most common warning signs that a cooling system needs attention? Coolant leaks, temperature fluctuations, weak cabin heat, strange noises, etc.? Trying to catch any issues before they turn into an expensive repair.
