These trucks don't have a history of overheating problems so there's no need to over-engineer a solution to a non-existant problem. The stock radiator should do just fine. The 235 and 216 used the same radiators in the AD trucks.
My thought was to just try it and see, then fix any problem later if there is one, but thought I'd ask around in here to see if I should just skip right to a new one.
My engine is a 207, not 216. Not sure if that makes any difference in terms of what my radiator capacity/capability is compared to what was used for the 216's. Maybe it's the same as well. Don't know, but I guess I'll find out at some point when this project is complete! (This swap is not as simple as a 216-to-235 swap).
