Here is a nice small radiator and coolant reservoir tank that might work well for small water cooled engines such as the:
- Kubota EA, EB and EL series engines.
- Changfa type R165, R170 & R175 engines

I would think its large enough for engines up to 7hp & more.

Here is a larger radiator that is probably larger than needed for the small liquid cooled Kubota E series and Changfa R165 through R175 engines.

The Yamaha Banshee YFZ350 puts out around 34 hp.
I would think it should be a good fit for a Changfa type S195 engine.
That Yamaha rad might be a good size for my Witte BD Generator.
Tom, what's the hp rating on the Witte? I know they are large heavy engines.

Searching for small radiators !!!
Looks like Henry has another project on the go ? ;D

It's in the 10hp range and generates about 5kw.

Always thinking about something. The radiator will be for an upgrade on one of the Skunkworks projects. :)

That's one massive engine for 10hp. I was guessing around 14 to 16 hp. Has to be a low stress engine. And, it should last a while.

It's rated for 30k hours between overhauls.
That's a whole bunch of hours. There are a few modern engines that can claim 30k + hours. They are ran continuously. The Witte seems like a simple engine that requires only basic hand tools to service. That is a huge plus on its side. And, the Witte will most likely run on lower grade fuel.
Tom,
30K hours !!!!
You had better find a use for it soon, then put it into action, then.... by the time you are 93 years old it might need a rebuild. ;D
Right now I am looking for a fuel pump element. There is felt play in the one in there now and it's leaking fuel into the crank case.
