Anyhow overheating issues are not usually 'engine specific' in the regard that most problems will lie with the RW pump, intake strainer, low FW reservoir levels, FWC pump, and often a clogged mixing elbow that restricts cooling water flow.
If mechanics have investigated and not been able to find the problem, either they're not very good mechanics or it's an oddball issue and/or and oddball engine.
So we need more details and information on what's been checked and confirmed to be OK.
btw.. welcome to the forum. I've moved your post to the Diesel Engine forum, a more appropriate place for it.

New engine in a e37
URGENT! Must be out of Bresil in the next two months (by law) Engine overheating. Mecanics (many) don't find the problem. Somebody alreday changed the engine Perkins 4.108 for an other make who fit well in a Endeavour 37? Many thanks!
