VH157121880A OIL COOLER ELEMENT

Product Overview

The VH157121880A Oil Cooler Element is a critical engine component for the Kobelco SK200-8, SK210LC-8, and SK250-8 excavators equipped with the Hino J05E engine. This oil cooler element, also known as an oil cooler core or engine oil cooler, is responsible for regulating engine oil temperature by transferring heat from the oil to the engine’s cooling system . It plays a vital role in maintaining optimal oil viscosity and preventing the engine oil from breaking down due to excessive heat.

The Kobelco SK200-8 and SK210LC-8 are 20-21 ton class excavators, while the SK250-8 is a 25-ton class machine . All three models are powered by the Hino J05E engine, a 4-cylinder, 5.123-liter turbocharged diesel with intercooler . The J05E engine utilizes a liquid-cooled oil cooling system where engine oil flows through the oil cooler element to dissipate heat, maintaining the oil at its optimal operating temperature .

This oil cooler element works in conjunction with the engine’s oil filter and oil pump to maintain proper oil temperature and cleanliness . A failing or clogged oil cooler element can lead to engine overheating, oil pressure issues, and accelerated wear on critical engine components. Replacing a worn or damaged oil cooler element with this OEM-spec VH157121880A component restores proper oil cooling and engine protection .

Please verify your machine’s serial number and engine model before purchasing. The oil cooler element is located within the engine’s lubrication system and requires proper installation to function correctly .

How the Oil Cooler Element Works

The oil cooler element is an integral component of the Hino J05E engine’s lubrication system :

System Overview

Engine oil is circulated by the oil pump through the oil cooler element before being sent to the oil filter and the engine’s moving parts . As hot oil passes through the cooler element, heat is transferred to the engine coolant flowing around it, effectively lowering the oil temperature before it returns to the engine .

Benefits of Proper Oil Cooling

• Maintains Oil Viscosity: Prevents oil from thinning at high temperatures, ensuring proper lubrication of engine bearings and moving parts.

• Prevents Oil Degradation: Reduces thermal breakdown of oil additives and base stock, extending oil life.

• Reduces Engine Wear: Keeps oil at optimal operating temperature for maximum protection against friction and wear .

Related Components

According to the Hino J05E workshop manual, the oil cooler assembly works with the following components:

• Oil filter and oil filter cap 

• O-rings (non-reusable) 

• Oil pan and drain plug 

Signs Your Oil Cooler Element Needs Replacement

The oil cooler element can fail due to clogging, cracking, or contamination. Replace your VH157121880A oil cooler element if you observe:

1. Engine Overheating: The engine runs hotter than normal or the temperature gauge reads high, indicating the oil is not being cooled effectively .

2. Oil Leakage: Visible oil leaking from the oil cooler area may indicate a cracked or damaged cooler element .

3. Coolant Contamination: Oil in the coolant or coolant in the oil indicates a failed oil cooler element allowing cross-contamination between systems .

4. Low Oil Pressure: A clogged oil cooler element can restrict oil flow, leading to low oil pressure warnings .

5. Loss of Engine Oil: Unexplained oil loss without visible external leaks .

6. Increased Engine Wear: Premature wear of bearings or other engine components due to inadequate oil cooling .

7. During Scheduled Maintenance: Replace the oil cooler element when servicing the engine oil system or if the oil filter replacement schedule indicates .

Benefits

Why choose our VH157121880A Oil Cooler Element for your Kobelco excavator?

Installation Tips

• Professional Installation Recommended: Oil cooler element replacement requires draining engine oil and coolant, and proper torque procedures. Professional installation by qualified technicians is strongly recommended.

• Drain Fluids: Drain engine oil and engine coolant before removing the oil cooler element .

• Replace O-rings: Always install new O-rings when replacing the oil cooler element. According to the Hino J05E workshop manual, O-rings are non-reusable .

• Clean Mounting Surfaces: Remove contamination on the joint surface between the oil cooler and cylinder block using a scraper .

• Apply Liquid Gasket: When reinstalling, apply liquid gasket [Threebond TB1207 (silver) or equivalent] continuously at a width of 1.5 to 2.5 mm .

• Install Within Time Limit: Install the oil cooler within 20 minutes after application of the liquid gasket .

• Check D-ring Orientation: If applicable, face the D-ring flat area toward the oil cooler .

• Dispose Properly: Dispose of drained engine oil in accordance with specified environmental procedures .
