Summershandy 54 Posted December 24, 2017 Once again, inquiring minds want to know. At the front of the rad, the "shroud" has 2 removable covers. I've seen pictures of other engines with or without them on. I don't see where they would be used for any access to anything. I'm thinking they would be used in the winter months a lot like the grill covers to see on the exterior of trucks to help with engine heat. I also would imagine having them off in the summer would create a better air flow for the rad. Any thoughts anyone? Share this post Link to post Share on other sites
GARY F 195 Posted December 24, 2017 My guess it helps to force the air to the rad. Share this post Link to post Share on other sites
