180 thermo opens at 180* and allows coolent to flow thru. you can try putting the stock 195* thermo back in.
ive resently raised my fan settings back up, i was tired of waiting forever for the car to get up to operating temps. plus the heat
dident work as good then :/
you can try putting the stock thermo back in, but the fans are still gonna run when there supposed to be turned on (its in the tune, you can adjust at what coolent temp the fans come) or you can find someone with a tuner to adjust when the fans come on.
