My oil cooler was internal to the radiator... is yours off to the side or in front of the radiator? My PS cooler is off to the side.
Mmmmm...Good point. I haven't traced-down the plumbing. Could be an auxilliary trans cooler instead of an engine oil cooler on the left side of the rad, beside the aux. cooling fan.Power steering cooler on my 3500 is quite far outboard on the drivers side. The truck is also equipped with aux trans cooler and aux cooling fan.
I want to say that the power steering cooler is mounted on the core support, not in front of the radiator or AC condenser.
Seems to me there's internal rad coolers on both rad tanks.
