the oil cooler only fits with the correct side against the oil filer
flange/boss,
and naturally the hose nipples need to point up.

it really doesn't matter which way the coolant flows through it ..
and your hoses will fit naturally where they should.

I just looked at one of my vans ..
the forward pipe connects to the forward-ish pipe nipple.

the water pump pipe connects to the aft nipple.
I wouldn't be possibly to do it incorrectly even.
