99 Yukon Radiator Replacement - Suggestions?

[drakon543]

Correct, no external cooler on the driver's side, only the cooler previously pictured on the passenger side. When I removed the hard lines of the radiator the passenger side was transmission and driver's side was oil, with each having about a cup or so of fluid coming from the lower connections.

east was refering to the driver side lines that had engine oil in them. the engine oil cooler is built into the radiator. they only came with an aux additional trans cooler for the towing package as far as i know.
