Follow the TOP radiator hose to the engine block Remove the hose from the engine block. Thermostat should pop out. Some screw in, most pop out.
It is located at the engine at the upper rad hose, When you replace it, make sure the spring goes toward the engine.
I don't know about the 4 Cylinder, but the 2.5L V6 1999 626 has the thermostat on the lower hose area, where it attaches to the engine/thermostat housing. To replace it, I had to take the entire air box out. It took a bit of work. You also need to take off the heat pipe mount attached to the engine in order to pull the thermostat housing apart.Not the easiest job for a thermostat replacement.
According to Haynes Repair Manual #61042 for the years 1993 thur 2001 fot the Mazda 626 & MX-6 Ford Probe the engine thermostat is located on the driver's side of the engine compartment under the air breather. It is necessary to disconnect the ram-air hose & remove the air-filter compartment to reach the thermostat. The thermostat is held in place by two bolts & an "O" ring gasket. I had to replace mine & is took a "little while" to remove everything to get to the thermostat, replace the thermostat & then replace everything back in place as it was before.
