This radiator cross-references APDI 8012771 and Spectra Premium CU2771 for the same application.
Common Cooling System Issues It Can Address
- Coolant leaks from a cracked or aging radiator tank
- Overheating caused by restricted or inefficient heat transfer
- Reduced cooling performance from worn core fins or internal wear
- Fitment problems from a damaged or incorrect replacement radiator
- Cooling system service needs on high-mileage BMW X3 models
Installation Notes and Tips
Verify radiator dimensions, inlet and outlet sizes, and cooler configuration before installation on your BMW X3. Inspect hoses, clamps, and surrounding cooling system components for wear before transferring the new radiator into place. Confirm that the radiator seats correctly and that all connections are tightened to factory specifications during installation.
Quality Assurance
OSC tests complete radiators up to three times during production. The engine and transmission cooler circuits are checked before tank installation, the core is tested before assembly, and the finished radiator is tested again after assembly to confirm sealing and performance.
