suzuki df 140 help

what thermostat should I use 60 or a 70 . I was thinking the 70 would be better for fuel economy . cant read the old one

which one does it call for by the serial number? On fuel injected engines, they are programmed to work at specific temperatures, if you change the temp without changing the programming, it can cause problems. Just go with what it calls for by serial number

Use the 60, the 71 is listed as an optional t-stat most likely for cold weather useage.
