11427525333 covers a BMW oil-to-coolant heat exchanger used across several engine and chassis references, with Model intentionally left blank. Yongshang Auto records this item as OC260727-004 for purchasing traceability and sample review.
The source application information covers BMW 3 Series, 5 Series, X1, X3, X5, X6 and Z4 source applications. Because compatibility may span multiple models or production changes, the Model filter remains blank and final approval should use vehicle-specific evidence.

Lubrication Heat Rejection Across BMW Platforms
The layered core removes heat from circulating engine oil and releases it into the coolant circuit. This helps the lubrication system maintain predictable viscosity as operating conditions change.
Because the OE reference may appear across several BMW series, product approval should focus on engine-specific catalogue data rather than a single marketing model name.
Engine-Based BMW Compatibility Verification
Use the VIN to identify engine designation, production month and the original cooler number. Compare the cooler-to-housing interface and all port positions before confirming interchange.
Measure the core depth and inspect the coolant-neck angle. Review the gasket layout carefully because a mismatched seal can mix fluids or cause an external leak.
BMW Sealing Surface and Core Assessment
Inspect the stacked plates for compression damage and examine the coolant connection for deformation. Oil passages must remain free from chips, packing material and corrosion residue.
During service, diagnose the filter housing, seals and cooling system as a complete assembly. Refill with approved fluids and check for contamination after the first operating cycle.
Wholesale Supply and Sample Approval
Use 11427525333 as the principal sourcing reference and OC260727-004 as the internal item code. Send order quantity, destination, carton marking and labelling requirements when requesting a quotation.
For technical approval, buyers may submit VIN data, engine information, measurements and images of the removed cooler. Packaging and mixed cooling-system orders can be reviewed before shipment.
Frequently Asked Questions
Why is the Model filter blank for 11427525333?
The source lists several BMW series, so leaving Model blank avoids presenting one chassis as the only supported application.
What is the correct way to confirm BMW fitment?
Use VIN-based catalogue data, engine code and production date, then compare the original cooler’s interface, ports and core depth.
Which sealing risks should technicians consider?
Incorrect gaskets, damaged mating faces or internal plate failure can cause external leakage or oil-coolant cross-contamination.
What should be cleaned during replacement?
Clean the cooler housing, oil passages and nearby coolant circuit, removing old seal material without introducing debris.
How can buyers request 11427525333 pricing?
Send the OE number, OC260727-004, volume, destination and packing details; include VIN or removed-part evidence for technical confirmation.
