I fought for years to get mine to cool..26 in rad 3 different types of cooling fans 2 different radiators ,,would be cool in traffic but heat up at highway speeds..Finally a guy had a radiator out of a Ford V10 pickup,,I made it fit,and with dual cooling fans it has a hard time getting to thermostat temp..I cant get it to run hot...most of the time I don't even use the fans, only when stopped in traffic...
