My advice after doing it is not to. Not until you start modding and notice an increase in normal operating temps.
Thats understandable, less time in the radiator, basically recirculating hot coolant. So maybe in conjunction with the pulley, you could have either a fan override or just set the ECM/PCM to turn on the fans at a lower operating temp? Cooling down the radiator significantly more, making up for short time spent in the cooling ducts?
Does that change anything significantly or would it be more worth it to just install a fan override ALONE to battle high temps on hot days?
