Q: Thermostat ? on 1995 Mazda MX-6

my '95 Mazda has been running hot when sitting still or slowing down. If I rev the engine to about 4 or 5k RPM it brings the temp back to normal.
Is it the Thermostat? And if so; Where is it located?

It never hurts to replace the thermostat, they wear out and need to be replaced every 60,000 miles or so.
I would also check the cooling fan operation, it may be part of your problem.
