The fan on my 59 Lark 6 is a fair way, about 2 1/2" from the radiator. This seems to be a long way considering the other vehicles I have worked on over the years. Pulling the radiator on some cars I have owned took great care not to scrape the fins of the radiator with the blades of the fan.
The question is how close should the fan be? Does it need a shroud? Is there supposed to be a protection guard at the top of the radiator?
