How to replace the outlet radiator hose (LF1, LLT) on Cadillac CTS?

Draining coolant should be the first step before exchanging the radiator outlet hose (LF1, LLT). Raising and supporting the vehicle is the next step for the replacement procedure. Begin by removing the air cleaner outlet duct followed by the front air deflector. The hose clamp screws on the J 38185 - Hose Clamp Pliers so the radiator outlet hose clamp can be readjusted at the engine coolant inlet pipe. The technician will then detach the radiator outlet hose from the engine coolant inlet pipe. The process starts by relocating the radiator outlet hose clamp at the radiator before extracting the hose from its position at the radiator. After this remove the hose from the vehicle. When installing the radiator outlet hose into the vehicle first apply clean coolant on its inside diameter. Install the radiator outlet hose by first positioning the clamp at the radiator. Users should then place the hose between the radiator and engine coolant inlet pipe. J 38185 - Hose Clamp Pliers can be used to relocate the radiator outlet hose clamp to its position at the engine coolant inlet pipe. Place the front air deflector next and reduce the vehicle height before setting the air cleaner outlet duct into position. Finally, fill the cooling system.
