I think the original question was: "How do I adjust the thermostat flaps?"
Drive the car for 10-30 mintues, until you are confident that the engine is fully warm. Then go to the engine bay, locate the cable that actuates the thermostat flaps, and loosen the pinch bolt that holds the cable onto the flaps cross-shaft. The spring should force the flaps to the "maximum cooling" position, so you let them go there and you pull the cable so it is
just snug or has a
tiny bit of slack to it. Tighten the pinch bolt, and you're done!
Note: Make sure that the flaps go all the way to open when you do this. Apparently mine like to bind at about 1/2 way open....
