FAQ

Q1: How can I confirm this oil cooler core fits my Doosan 250LC-V?
A: Please verify the part number stamped on your original oil cooler. It should match “65.05606-5020”. Additionally, confirm your engine model is the D1146. If your machine has a different engine variant, please contact our support team with your machine serial number for verification.

Q2: Is this a complete oil cooler assembly or just the core?
A: This product is the oil cooler core (the internal heat exchanger matrix) only. It does not include the housing, gaskets, or mounting brackets. We recommend replacing all related gaskets and seals during installation to prevent leaks.

Q3: What is the recommended maintenance after installing a new oil cooler core?
A: After installation, run the engine and check for leaks at the connection points. Monitor the engine oil temperature gauge during the first few hours of operation to ensure it stays within the normal range. It is also good practice to check the engine oil level and condition, as old, contaminated oil can reduce the efficiency of the new cooler.
