FYI, this is actually a Suzuki with Johnson badge.

My OE service manual states operating temp should be 118F-126F.
Per manual, testing in water with digital thermometer, mine starts to open about 138F and is fully open around 145F.

New t-stat #5031758 states 60C or 140F. Why the difference between manual and new temps? Buy new or reuse? This is the original t-stat.
Any input?

Mike
