Radiator Assembly

The first steps to replace the Radiator include disconnecting the negative Battery Cable as well as removing the Radiator Cap. Raise your vehicle properly and eliminate any safety hazards before removing all lower shroud clips. Drain the cooling system by opening the Drain Plug until the required fluid leaves the system. Keep the Drain Plug closed after the procedure. Automatic transmission operators should detach their transmission oil cooler lines located at the bottom of the Radiator before sealing open ends to block leakage. After lowering the vehicle you should disconnect the lower Radiator Hose before proceeding to take off the Radiator overflow hose then the upper Radiator Hose. Secure the Radiator by removing two upper Radiator shroud clips while removing one bolt from each Radiator side on the installation process without damaging the Radiator fan. The Fan Shroud needs to be leaned toward the engine while you lift the Radiator out of its position in the vehicle. To mount the Radiator position each bolt on both sides then put in the 2 upper Radiator shroud clips along with the upper Radiator Hose and Radiator overflow hose. Apply needed torque to the vehicle before mounting the lower Radiator Hose, transmission oil cooler lines and installing the 2 lower Radiator shroud clips. After vehicle position is lowered you must fill the cooling system before reconnecting the negative Battery Cable. The inspection process ends when you operate the engine while checking for coolant leaks and making sure the system has the right coolant level together with looking for automatic transmission fluid leaks and confirming correct fluid level.

The Radiator service commencement requires disconnecting the negative Battery Cable followed by Radiator Cap removal. Properly elevate the car and remove all the lower shroud clips before draining the cooling system through the Drain Plug. Close the plug after draining. You need to disconnect Automatic Transmission Oil Cooler Line connections located at the Radiator bottom while applying caps to these open tubes to stop fluid leaks. You must remove the lower Radiator Hose followed by lowering the vehicle before taking out the Radiator overflow hose and upper Radiator Hose. The installation requires removal of two upper Radiator shroud clips together with one bolt from each Radiator side without damaging the fan part of the Radiator. The engine-side of the Fan Shroud should lean toward the engine block while the Radiator must be lifted vertically through the vehicle opening. Position the Radiator inside the space before securing it with one bolt each side and attaching the upper Radiator shroud clips as well as the upper hose and the overflow hose. The installation of the lower Radiator Hose and transmission oil cooler lines requires a maintained vehicle height for secure attachment at the bottom of the Radiator. Before lowering the vehicle reattach the negative Battery Cable then add fluid into the cooled system through the installed clips on the lower Radiator shroud. To complete the procedure start the engine while inspecting for coolant leaks and verifying proper cooling level and automatic transmission fluid conditions with appropriate fluid levels.

Lean the fan shroud toward the engine and lift the radiator out of the vehicle.
