13. Remove transmission oil cooler tubes support bracket at left side of radiator (if equipped) (2).
CAUTION: Plastic tanks, while stronger than brass are subject to damage by impact, such as wrenches.
14. Remove the two torx screws located on the upper radiator support that hold the upper radiator mounting brackets.
15. Tilt the top of the radiator rearward so the mounting brackets slide out of the upper core support.
16. Remove radiator/condenser assembly by lifting the assembly out of the vehicle between the engine and the core support.
17. Separate the A/C condenser from the radiator.
Cleaning
Clean radiator fins are necessary for good heat transfer. The radiator and air conditioning fins should be cleaned when an accumulation of debris has occurred. With the engine cold, apply cold water and compressed air to the back (engine side) of the radiator to flush the radiator and/or A/C condenser of debris.
Inspection
Inspect the radiator tanks for cracks, broken or missing fittings also inspect the joint where the tanks seam up to the radiator core for signs of leakage and/or deteriorating seals.
Inspect radiator core for corroded, bent or missing cooling fins. Inspect the core for bent or damaged cooling tubes.
