Restore Efficient Engine Oil Cooling with a Complete OEM Housing Assembly

Ensure your engine oil maintains the optimal temperature for lubrication and performance with the genuine VH157012350A (S1572-01542) Oil Cooler Case Sub Assembly. This critical component is a direct OEM replacement for the external housing and core support structure of the engine oil cooler on J05E and J08E engines in Kobelco SK200-8, SK210-8, and SK250-8 excavators. A damaged or leaking oil cooler case can compromise the entire cooling circuit, leading to overheating, oil degradation, and potential engine damage. Restore the integrity of your oil cooling system with this durable, ready-to-install assembly.

Product Overview

The VH157012350A (S1572-01542) Oil Cooler Case Sub Assembly is the primary structural housing that contains the oil cooler core (element). It provides the sealed passages that direct hot engine oil and engine coolant through the cooler, allowing heat to transfer from the oil to the coolant without the two fluids mixing. This sub-assembly typically includes the main cast or fabricated case, internal baffles, and mounting provisions for the cooler core and associated gaskets/seals. Our replacement unit is manufactured to exact OEM specifications, ensuring perfect fitment to the engine block, correct alignment with coolant and oil lines, and reliable sealing to prevent leaks and cross-contamination.

Key Features & Benefits

• Direct OEM Fit & Compatibility: A perfect replacement for part numbers VH157012350A and S1572-01542, guaranteeing correct mounting, port alignment, and sealing surface integrity for your J05E/J08E engine’s oil cooling system.

• Ensures Efficient Heat Transfer: Provides the proper internal flow channels for both oil and coolant, ensuring maximum heat exchange efficiency to keep engine oil within its optimal operating temperature range.

• Prevents Leaks and Fluid Mixing: A robust, undamaged housing is essential for maintaining separate, sealed circuits for oil and coolant, preventing the catastrophic mixing of fluids that can destroy an engine.

• Durable Construction: Made from high-quality aluminum alloy or other corrosion-resistant materials designed to withstand the thermal expansion, pressure cycles, and vibration of engine operation.

• Complete Structural Solution: Replaces the entire outer casing, which is often more cost-effective and reliable than attempting to repair a cracked, corroded, or damaged original housing.

• Essential for Cooler Service: This assembly is the foundation for any oil cooler repair or rebuild. When replacing a clogged or leaking cooler core, installing it into a new or like-new case ensures long-term reliability.

Frequently Asked Questions (FAQ)

Q1: What symptoms indicate a problem with the oil cooler case (VH157012350A)?
A: Signs include:

• External oil or coolant leaks originating from the cooler housing seams or mating surfaces.

• Engine overheating due to impaired oil cooling.

• Evidence of oil in the coolant or coolant in the engine oil, suggesting internal seal failure within the cooler assembly (though this could also be the core or gaskets).

• Physical damage such as cracks, corrosion holes, or stripped threads on the housing.

Q2: What is included in this “sub-assembly”?
A: The VH157012350A typically includes the main housing/case only. It does not include the internal cooler core (element), the end cap gaskets/O-rings, or the oil cooler-to-block gasket. These are usually separate part numbers and must be ordered for a complete repair.

Q3: Can I install this case myself and reuse my old cooler core?
A: This is an advanced repair. It requires draining engine coolant and oil, removing the entire oil cooler assembly, disassembling it, and installing the new core (or a cleaned/replacement core) into the new VH157012350A case with new seals. It demands mechanical skill and meticulous cleanliness. Professional installation is recommended.

Q4: Why replace the entire case instead of just sealing a leak?
A: Cases can develop cracks or porosity that cannot be reliably repaired with sealants. For leaks at sealing surfaces, new gaskets may suffice. However, if the housing itself is corroded, warped, or cracked, replacement with this sub-assembly is the only permanent, reliable solution.

Q5: Is this an OEM genuine part?
A: This is a high-quality, OEM-compatible replacement part manufactured to the exact specifications of the original VH157012350A / S1572-01542 component, ensuring perfect fit and function.
