now if you drive like grandma,then disregard all of my replies even though the water temp is still going to rise at idle or in traffic with stop and go.especially if you dont have the uprev fan control.with the 180 stat,my water wants to run at 192 and jump to 200 at idle.i have also read the ecu starts cutting timing when water hits 190.so with the oem stat,you dont have very long from a cold start before the ecu starts to cut timing,or power.my car runs great when my water is at 160-170.wish i could keep it there 100% of the time after initial warm up .
