My BBC typically runs around 190 to 200 degrees while going down the road in hot weather. Conventional belt driven fan. I know that is not a bad thing. At stop lights it starts to climb and I have not just sat there or idled it to see how far it would go. I am sure it will get over 220. Just wondering would it help to put a fan in front of the radiator to keep air flowing or would the fan obstruct more than help. I do not have a shroud so I will do that first to see the effects. I have not been caught in a traffic jam or bumper to bumper yet. What is the preferred distance of fan to radiator?
