PS heat sink cooler

Going to add a power steering heat sink style cooler. Stock Chevy pump and hydro boost, no steering ram assist.

What is everyone running 1 or 2 pass?
The ones I am looking at the 1 pass has 3/8" inlet/outlet, the 2 pass has 1/4". Not sure which is better.

Thanks

They are ok, in the rocks, crawling they have a limited capacity for heat dissipation, I am planning to add a fan mounted cooler soon like this

PSC told me to get the single pass for my full hydro setup due to flow thru. I was told the 2 pass wouldn’t pass enough volume thru.

I talked to several steering manufacturers and all of them recommended a single pass cooler. The smaller passage and fittings of the dual pass add too much flow restriction. I'm running a Russell 15" cooler with -8AN fittings and hoses with CB high flow pump on my hydro assisted TJ and have no cooling issues.
