I've got a 360 with a brand new radiator and I've noticed some annoying behavior this summer/fall. When idling temp climbs to 220+, I've never seen 225 and going down the road it runs right at 200. The vehicle has always had a flex fan in it. Would a clutch fan do better in this situation? I do have a good shroud. Is 220 to high? Should I just push my alarm light up to 230F? Am I worrying about nothing?
