2008-2014 Cadillac CTS OEM Radiator for 3.6L Automatic Transmission
Direct replacement OEM radiator engineered for 3.6L engines with automatic transmission cooling. Maintains factory cooling capacity and fitment without modification. Built to handle daily driving and moderate performance use.
Does this radiator include hoses and clamps?
The radiator assembly ships alone. You'll reuse your existing hoses and clamps from the original unit — they're designed to fit directly.
Will I need a new thermostat when I install this?
The radiator itself doesn't require a thermostat change. If your old thermostat is still functioning, keep it. If you're experiencing cooling issues beyond the radiator, diagnose that separately.
Do I need to flush the cooling system before installation?
Yes — flush the system before dropping in the new radiator. Old coolant can clog a fresh core and defeat the purpose of replacement. Use distilled water to rinse, then refill with the correct coolant type for your vehicle.
