I resolved this problem with a larger Dewitt's radiator and New Dual, higher Rpm spal fans, and a 160 T-stat. The stat is a "part" of the solution only.

A huge debate for decades..... not going to be solved here but one of the best articles I saw about it was from Summit.

Darryl,

Thank you for the reminder and link. Good info and article. I might eventually do the spal fans like you and others. I do have an upgraded radiator that has been doing well for me so far, but Japan summers are brutal. Thanks again.
