don't believe it came with a shroud and i can't get back into storage to check to radiator tank. Its gets hot when idling or moving slowly. Has a new core put in the rad that seems to work b well on the highway under light load. Would changing the stock help?
I had a similar issue with my /6 in my Duster. Driving was no issue, but it was getting hot at idle and under load. That OE /6 radiator is just damn small.
I tried replacing the thermostat, even going so far as removing it. I flushed the system and even even replaced the heater core. Same problem.
Ultimately I ended up putting a stock radiator for a V-8 in its place. They built 76 SE's with V-8's and you should have zero issues dropping one in there.
I put a 26" radiator in place of that little one and my car hasn't even come close to getting hot since.
I wouldn't mind having an upper fan shroud, but I want that more for finger preservation than cooling issues.
