The previous limited discussions on this topic are pretty old, and not relevant to my model. The manual for the 2012 does not mention or recommend a PS cooler for towing, just the ATF cooler. Did the OE cooler improve on these later models?

I have done the rest of the towing mods as recommended, but was wondering if I should also add a 3rd party PS cooler. The only reason offered for needing this is the higher RPMs that the engine runs while towing. But I routinely cruise at 75-80 mph (Texas ), so cruising at 60-65 with the trailer shouldn't be that much different, I would think.

Recommendations for a DIY after market PS cooler?

 

The Factory Honda Power Steering cooler should suffice for towing as well as regular driving. Just be sure to change the PS fluid as reccomended ( every 60k under SEVERE conditions ) The ATF cooler IS DEFINITELY needed if youre towing a heavy trailer.

 

Thanks, I presume you are talking about the original stock PS cooler that came with the vehicle. That's what I was thinking also. I have installed the recommended Honda ATF cooler.
