I am wondering if I can install a lower temperature thermostat to my Smart Passion 2009. The temp here is almost all the time above 80 F and even higher in the traffic jams . I would like the thermostat to open earlier and compensate better for the high temps outside. I did lower my wrangler to 185 from 195 and is performing better. The difference is that the Smart motor is in an aluminum block and the Jeep is an iron
one. I do not know at what temp the Smart therm. opens. Do any of our Smart owners know? Would like to see your comments on this. Would the computer and sensors be affected or give different readings.
Pls advice!!!!! Tks!
Robert said it all. Messing with the t stat is what was done on cars before computers, fuel management, and emission control systems. You will see no benefit from changing your t stat temperature rating in a modern vehicle in normal use.
