Cold Case Radiator what fan and shroud are you using ?
Old post but chiming in maybe this helps someone ….As of September 2024 the “gap” problem is still not resolved just installed a cold case radiator and mancini fan shroud and there is a fat *** gap by the top tank. I’m thinking some high heat silicone rubber strip to fill in the gap . My thought is the silicone is a safer bet with any vibrations while running …it’s a tight fit right where the hoses are .I had to slightly modify the shroud nothing crazy just a little cutout so the hoses fit comfortably . I think if Cold Case just pushed back the side brackets ~1/2 inch it would definitely help or somehow add extra material on the sides of the tank to have the mounting holes practically flush.
