Being the owner of a Luxo Barge ( how I love that Name ) ie a 2003 607 V6 I would like to know If there Is someone out there that can tell me which way does the oil flow into the Oil Cooler. Vehicle is fitted with a 4 speed auto. Looking from the front of the vehicle does the oil enter the cooler via the hole in the front cooler hold down bolt and return to the gearbox via the rear hold down bolt or Vice Versa
