Dodge Repair: trans. cooler line locations: 04 Dakota, line attachment points, radiator

Question
Is the upper or lower line to the radiator the return line? [for aux. cooler] 2003 dakota V6 auto. 4wd,thanks

Answer
Hi Todd,
If these lines are positioned on the right side and low on the radiator assembly, then the '04' manual I have shows the upper one is the supply line and the lower is the return line to the transmission. It should be applicable to your '03. Let me know if that is not where your line attachment points are positioned.
Please 'rate' my answer (see below).
Thanks,
Roland
