Product Details

Product Overview

This high-quality Oil Cooler Core, referenced under part number 1-21723-0290, is a direct replacement component specifically designed for the Isuzu 6BD1 diesel engine. It is a critical component for the engine’s cooling system, ensuring that engine oil is maintained at an optimal operating temperature to prevent overheating and premature wear.

Commonly used in heavy machinery such as the Hitachi EX200-1 excavator, this oil cooler core is manufactured to meet or exceed OEM specifications. It is a brand new, 100% new unit, offering a reliable solution for maintaining the thermal balance of your 6BD1 powerplant. Please verify your existing part number (1-21723-0290) and engine model to confirm fitment before purchase.

Key Features & Benefits

• Precise Fitment: Designed with exact dimensions and port configurations to match the OEM 1-21723-0290 specification for the Isuzu 6BD1 engine and Hitachi EX200-1 chassis.
• High Thermal Efficiency: The core construction maximizes surface area for superior heat dissipation, ensuring stable oil temperatures under heavy load conditions.
• Durable Construction: Manufactured using high-grade aluminum or copper-brass materials (as per OEM spec) to resist corrosion and vibration fatigue common in construction equipment.
• 100% New Condition: This is a brand new, non-remanufactured unit, ensuring zero wear and maximum service life from the moment of installation.
• Direct Replacement: Engineered as a direct bolt-on replacement, requiring no modifications to existing oil lines or mounting brackets.
• Cost-Effective Maintenance: Replacing a clogged or leaking oil cooler core is significantly more economical than replacing the entire cooler assembly or risking major engine damage due to overheating.

FAQ

1. Is this the complete oil cooler assembly or just the core?

This listing is for the Oil Cooler Core (the internal fin and tube element) only. It does not include the outer housing, gaskets, or O-rings. You will need to transfer the new core into your existing housing. We recommend purchasing a gasket and O-ring kit separately for a complete seal.

2. How do I know this will fit my Hitachi EX200-1?

This part is specifically designed for the Isuzu 6BD1 engine, which is the standard power unit for the EX200-1. To confirm compatibility, please check the part number stamped on your existing oil cooler core. It should read 1-21723-0290 or a similar variant. You can also measure the core dimensions (length, width, and thickness) and compare them with our product images. If in doubt, please contact us with your machine serial number.

3. What are the signs of a failing oil cooler core?

Common symptoms include: 1) Engine oil overheating (indicated by high oil temperature gauge readings). 2) Coolant in the oil (appears as a milky, frothy substance on the dipstick). 3) Oil in the coolant reservoir. 4) Visible leaks from the cooler housing area. If you notice any of these issues, immediate replacement is critical to prevent catastrophic engine failure. Our core is a direct solution for this problem.
