The thermostat on the 2002 Mazda 626 2.5 liter V6 is located at the opposite end of the lower radiator hose (near the block). It is nestled between the air-cleaner assembly and the intake manifold (on the driver side). You have to first remove the air-cleaner housing (The top half has several things attached to it; you don't have to completely remove the top half - just sort of move it aside after it hans been unencumbered; the bottom half must be completely removed as this is the area you will be working in.) The thermostat housings' top half can then be ubolted from the bottom half but you can not remove it or pull it aside to gain access to the actual thermostat until you unbolt the ignition coil pack. Mazda uses a strange metal sleeve to protect the lower radiator hose (I assume that's what it's for). There are three bolts holding the pack on (if I remember correctly, two of them hold the sleeve in place as well). After you free the sleeve you can then move the thermostat housings' top half aside and pull the thermostat out. Good luck putting it all back together - it's sort of like a jigsaw puzzle. BTW this is by far the hardest thermo I've ever had to replace.

Follow your upper radiator hose away from the radiator. there will be either a little block or snub nosed area. behind that should be your thermostat. sometimes it's a little bit more difficult to get to, but it is usually an easy remove and replace.

Where is the thermostat located in my 1995 mazda 626

The thermostat is located on the engine block, where the upper radiator hose connects to the engine. You'll see a large elbow-like component that is attached to the engine with 2 bolts.
Just follow that upper radiator hose and you got the location. When you remove that housing (elbow-like component), you'll see the thermostat.
Make sure you note which end of the thermostat is up and which end is down. Don't reverse the install.
