This may be of interest to some folks who wish to have more cooling.

Not sure I understand the description: "New, radiator and fan for small air cooled engines"
But, agree it could be used to supplement cooling in a WATER-COOLED vehicle.
In a motorhome, pretty easy to put in a "T" with ball valves or 3 way ball valve off the hoses to the dash heater core.
