Thank you for choosing SPARKLING MACHINERY.
The 13F52000 / 400206-00340 hydraulic oil cooler is built to survive the high structural vibrations and harsh environmental dust common to heavy mining and earthmoving zones. Constructed from premium-grade brazed aluminum, this radiator group provides exceptional heat transfer rates while maintaining low internal flow resistance. Keeping hydraulic oil within its optimal temperature window preserves fluid viscosity, ensures crisp joystick responsiveness, and prevents rapid wear on internal pump components.

Why choose the SPARKLING NEW 13F52000/400206-00340 Oil Cooler?
-
- Brazed Aluminum Bar-and-Plate Core: Engineered with high-strength internal fins that withstand heavy structural pressure spikes while maximizing external cooling air contact.
-
- Anti-Clogging Louver Design: The exterior cooling fins are spaced to minimize debris accumulation from flying dust, straw, or wood chips, ensuring consistent airflow.
-
- TIG-Welded Side Tanks: The oil fluid tanks are robustly welded to the core to eliminate edge leaks and stress fractures caused by continuous thermal expansion and contraction.
-
- Direct Bolt-On Fitment: Designed with the exact mounting bracket locations and high-pressure hose connection threads designated by Doosan part numbers 13F52000 and 400206-00340.
FAQ
What are the primary signs that an excavator's hydraulic oil cooler is failing or restricted?
The most common indicator is an "Over-Temperature" warning alarm flashing on the cabin display screen during heavy digging shifts. Physical signs include an immediate loss of hydraulic power and speed once the machine runs for an hour, structural oil weeps pooling along the radiator frame bottom, or external cooling fins that are heavily crushed, packed with mud, or eroded.
If my main hydraulic pump explodes, do I need to replace the 13F52000 oil cooler?
Yes, or perform an extensive industrial flushing process. When a hydraulic pump fails catastrophically, it pumps thousands of microscopic metal shavings directly into the return lines, which lead straight to the oil cooler. Because of the tiny internal cooling channels inside a bar-and-plate radiator, these metal shards get permanently trapped. Reusing the cooler without a thorough cleanup will allow those trapped flakes to wash loose and destroy your newly installed pump.
How can I safely clean the dust and debris out of my new oil cooler fins?
Use low-pressure compressed air or a gentle water stream sprayed from the inside out (opposite of the normal engine fan airflow direction). Never use a high-pressure industrial pressure washer close to the core, as the intense water pressure will instantly bend the soft aluminum cooling fins flat, blocking off air passages and causing chronic engine overheating.
