94 Terrano and 95 Mistral

Why the hell do these two trucks over heat so easily when towing? Slight hotter on open type roads but put a hill in front of them and besides nearly stopping on the up hill they both get quite hot when towing say a car trailer and car? Done this once with both and they both unperformed the same way? Is this just the old technology? Other that that they run cool and very light on diesel...........

I would say replace the fluid in the cooling fan viscous coupling and see what happens.

Might just do that cause i flushed the rads, put coolant back in, cleaned between the rads to make sure no leaves and dirst was in there but both do the same when loaded?
