Product Features

• Structure: A stacked plate design made from corrosion-resistant, high-temperature stainless steel. The plates are precision-welded to create efficient heat exchange channels, with integrated copper-plated mounting flanges for secure installation and enhanced heat transfer.

• Performance: Delivers high heat transfer efficiency to dissipate excess heat from engine oil, preventing oil degradation and maintaining lubrication performance. The robust stainless steel construction withstands high pressure and temperature fluctuations.

• Design: Directly interchangeable with the original equipment cooler core, ensuring a perfect fit and seamless integration with the engine’s lubrication system.

Core Function

1. Heat Dissipation: Cools hot engine oil using coolant from the engine’s cooling system, maintaining oil temperature within the optimal operating range (typically 80–100°C).

2. Oil Protection: Prevents thermal degradation of engine oil, preserving its viscosity and lubricating properties to reduce wear on engine components like the crankshaft and bearings.

3. Engine Efficiency: Maintains consistent oil temperature to ensure stable engine performance and extend the service life of both the oil and engine.

Engine Oil Cooler Core D18-002-30 SHANGCHAI – Premium Replacement for Heavy-Duty Diesel Engines

When your SHANGCHAI-powered fleet demands reliable thermal management, the Engine Oil Cooler Core D18-002-30 delivers precision-engineered heat dissipation that keeps lubricant temperatures within optimal operating range. Sourced directly from METTLEAD Truck Parts’ quality-controlled production line in China, this cooler core maintains consistent oil viscosity under extreme load conditions — protecting your engine investment mile after mile.

Designed as a direct-fit replacement for OEM part number D18-002-30, this oil cooler core eliminates guesswork during installation and restores factory-level cooling efficiency to SHANGCHAI D-series diesel engines commonly found across construction, logistics, and mining applications.

Key Features and Buyer Benefits

Engineered for Thermal Precision

• High-Density Plate-Fin Construction — Maximizes heat exchange surface area, reducing oil temperature by up to 15–20°C under full-load operation compared to worn or clogged units.
• Aluminum Alloy Core Material — Delivers superior thermal conductivity (approximately 205 W/m·K) while resisting corrosion from coolant and oil additives.
• Precision Brazed Joints — Vacuum-brazed seams ensure zero-leak performance at operating pressures up to 1.0 MPa, extending service life beyond 8,000 operating hours under normal conditions.

Direct OEM-Equivalent Fitment

• Exact Dimensional Match — Bolt pattern, port orientation, and gasket seating surfaces replicate the original D18-002-30 specification, enabling drop-in replacement without adapter modifications.
• Factory-Tested Seal Integrity — Each unit undergoes pressure testing at 1.5× rated operating pressure before shipment to eliminate DOA failures.

Procurement Advantages from METTLEAD

• Factory-Direct Pricing — No middlemen. You purchase at production-tier cost, improving your per-unit margin on fleet maintenance contracts.
• White-Label & Custom Packaging Available — Rebrand with your own logo and part numbering system for aftermarket distribution.
• Bulk Order Flexibility — MOQ as low as 5 pieces for trial orders; scaled pricing for container-volume purchases.

Technical Specifications

Application Scenarios and Compatible Vehicle Models

The Engine Oil Cooler Core D18-002-30 serves as a critical thermal management component across a wide range of heavy-duty applications powered by SHANGCHAI diesel engines:

On-Highway Logistics

Long-haul trucks and tractor units equipped with SHANGCHAI SC-series engines rely on this cooler core to maintain stable oil temperatures during sustained high-speed operation. Fleets running 12+ hour daily cycles particularly benefit from the enhanced heat rejection capacity.

Construction and Earthmoving Equipment

Wheel loaders, excavators, and bulldozers operating in high-ambient-temperature environments (quarries, desert construction sites) subject their engines to extreme thermal stress. This cooler core prevents oil degradation that leads to premature bearing wear and turbocharger failure.

Mining and Off-Road Vehicles

Dump trucks and haul vehicles working under continuous heavy-load conditions generate significant crankcase heat. The D18-002-30 cooler core dissipates this thermal energy efficiently, protecting critical engine internals during uphill loaded hauls.

Compatible Engine and Vehicle Platforms

• SHANGCHAI D6114 series engines (commonly found in XCMG, SANY, and LIUGONG equipment)
• SHANGCHAI SC9D / SC8D series engines
• SHACMAN trucks fitted with SHANGCHAI powertrains
• FOTON AUMAN heavy trucks with SHANGCHAI engine options
• Various Chinese-brand construction machinery OEMs specifying SHANGCHAI power units

Frequently Asked Questions

What symptoms indicate a failing Engine Oil Cooler Core D18-002-30?

Common signs include elevated oil temperature readings on the dashboard gauge, coolant contamination with oil (milky appearance in the expansion tank), oil pressure fluctuations, and visible external leakage around the cooler core mounting area. If your SHANGCHAI engine consistently runs oil temperatures above 110°C under normal load, the cooler core likely needs replacement.

Is this Engine Oil Cooler Core D18-002-30 an exact replacement for the original SHANGCHAI part?

Yes. This unit replicates the OEM D18-002-30 dimensional specifications, including bolt spacing, port diameter, and gasket contact surfaces. It installs directly into the original mounting location without any modification to hoses, brackets, or adjacent components.

How does the Engine Oil Cooler Core D18-002-30 handle high-ambient-temperature environments?

The plate-fin design provides approximately 30% more heat exchange surface area per unit volume compared to tube-type coolers. Combined with the high thermal conductivity of the aluminum alloy construction, this core maintains effective oil cooling even when ambient temperatures exceed 45°C — common in Middle Eastern, African, and Southeast Asian operating environments.

What is the expected service life of this oil cooler core?

Under normal operating conditions with properly maintained coolant (correct concentration, regular replacement intervals), the D18-002-30 cooler core delivers reliable performance for 8,000–12,000 operating hours. Premature failure is typically caused by coolant neglect (corrosion), over-pressurization, or physical impact damage.

Can I order a small trial quantity before committing to bulk?

Absolutely. METTLEAD accommodates trial orders starting from 5 pieces, allowing you to verify fitment, quality, and customer acceptance before scaling to container-volume procurement. Trial orders ship within 3–7 business days from confirmation.

Does the Engine Oil Cooler Core D18-002-30 come with gaskets and seals?

The standard package includes the cooler core unit. O-rings and mounting gaskets can be supplied upon request — please specify when submitting your inquiry so we can quote the complete installation kit.
