I have a 1957 TR-3 with engine upgrades, including the addition of a Hayden Electric Fan. Living in South Fla our summers are usually in the high 90's. Recently I was returning from a car luncheon and was caught in bumper tp bumper traffic in 98 degree weather. The temp gauge was between 185-230 most of the way home. Has anyone tried a shroud around the electric fan to get a better air flow to the radiator?
