2003 Cadillac CTS Parts Questions & Experts Answers

• Q: How to replace the oil cooler hose on 2003 Cadillac CTS?

  A: You should start by removing the oil filter adapter to replace the oil cooler lines and then separate the engine block's oil cooler outlet fitting and oil cooler inlet fitting . Lower down the vehicle while taking out individual components based on the rpo code. For lhd, take out the Wiper Motor module; lhd vehicles need removal of Wiper Motor module and rhd vehicles need air inlet grill panel removal as well as front air inlet panel assembly fasteners from battery tray and cowl prior to taking out the front air inlet panel assembly. Move on to remove the water crossover together with the Engine Oil Cooler outlet fittings and inlet fittings while keeping note of the 4 seals' placement. You should now detach the oil cooler lines that run from the engine. The installer must position the oil lines to the engine before installing the new seals to the Engine Oil Cooler inlet and outlet fittings with a torque of 30 nm (22 ft. Lbs.). The oil cooler inlet gets tightened to 30 nm (22 ft. Lbs.) and the outlet to 30 nm (22 ft. Lbs.). Place the water crossover back into position and support your vehicle at height after which install the engine block oil cooler inlet and outlet fittings using 30 nm (22 ft. Lbs.) torque. When complete with the installation place back the oil filter adapter alongside the components following the rpo code protocol: for lhd, the Wiper Motor module; lhd models require installation of the Wiper Motor module but rhd models need positioning of the front air inlet panel assembly at the battery tray followed by cowl securing with 6 nm (53 inch lbs.) fasteners along with air inlet grill panel installation.
