How do you repair the thermostat on a Mazda Millenia?

HOW TO REPAIR A THERMOSTAT FOR 1995 MILLENIA MAZDA? A few months ago I decided to replace the thermostat on my '95 Millenia (bad decision!!), since the repair shop wanted a couple hundred to do it. I spent an hour looking for it on the passenger side of radiator/cooling hoses. But no!! It is on driver side where the big rubber hose from bottom of radiator connects to a metal pipe and then to thermostat housing. Getting it all apart is the fun part (NOT!!) which took me another 2 or 3 hours. You have to remove or disassemble a bunch of stuff to get to the housing--but just follow your nose and it will all come apart. The new part was about $25, so the labor is the costly part. If you're patient, though, you can do it--and it feels good to get it in and working when you finish up!! Good luck!!
