Product Features

• Structure: A plate-fin heat exchanger made of corrosion-resistant stainless steel, with a multi-layered design to maximize heat transfer surface area. It features integrated inlet/outlet ports and mounting brackets for direct installation.

• Performance: Efficiently transfers heat from the engine oil to the coolant, maintaining oil temperatures between 80–100°C. The stainless steel construction resists corrosion and thermal fatigue, ensuring long service life.

• Design: Factory-calibrated to match the original engine’s flow and pressure requirements, with a direct-fit design that requires no modifications.

Core Function

• Prevents engine oil from overheating, which can cause oil degradation, loss of lubrication properties, and accelerated wear of critical engine components.

• Maintains consistent oil viscosity, ensuring reliable lubrication of the crankshaft, bearings, and camshaft across all operating conditions.

• Extends the service life of the engine oil and reduces maintenance costs by slowing the rate of oil breakdown.

Oil Cooler VG1246070012 for SINOTRUK HOWO Engines – OEM-Grade Thermal Management Solution

When your SINOTRUK engine runs hard under heavy loads, the oil cooler is the silent guardian that keeps lubricant temperatures in check and protects critical internal components from thermal degradation. The Oil Cooler VG1246070012 is engineered to deliver consistent, reliable heat exchange performance across demanding operating conditions — from scorching desert hauls to high-altitude mountain routes. Built to OEM specifications, this cooler ensures your fleet stays productive and your maintenance costs stay predictable.

At JINAN METTLEAD AUTO SALES CO.LTD., we supply this genuine-spec oil cooler directly from our China-based warehouse network, offering factory-direct pricing without compromising on quality control. Every unit passes strict dimensional and pressure testing before it ships to your door.

Key Functions and Benefits

Precision Thermal Regulation

This oil cooler maintains optimal lubricant temperature between 85°C and 105°C during sustained operation, preventing oil viscosity breakdown that accelerates bearing wear and shortens engine life. Its aluminum-plate heat exchange core maximizes surface area contact, dissipating heat up to 30% more efficiently than aftermarket alternatives with inferior fin density.

OEM-Matched Fitment

Manufactured to match the exact mounting dimensions, port alignment, and flow characteristics of the original SINOTRUK part number VG1246070012. That means zero modification during installation — your technicians can complete a swap in under 90 minutes with standard tools.

Extended Service Life

The cooler core uses corrosion-resistant aluminum alloy with brazed joints rated for operating pressures up to 1.2 MPa. Reinforced gasket seals resist degradation from high-temperature oil exposure, delivering a reliable service interval of 200,000+ km under normal operating conditions.

Reduced Downtime, Lower Total Cost

A failing oil cooler doesn’t just risk engine damage — it sidelines your truck. By maintaining proper oil temperature, this component protects turbochargers, pistons, and cylinder liners from premature wear, helping you avoid costly unplanned repairs that eat into your fleet’s profitability.

Technical Specifications

Application Scenarios and Compatible Vehicle Models

The Oil Cooler VG1246070012 serves as a direct replacement across multiple SINOTRUK platforms equipped with WD-series engines. Here’s where this part works hardest:

• SINOTRUK HOWO A7 6×4 Tractor Trucks — Long-haul logistics operations where sustained high-speed cruising generates continuous thermal load on engine oil.
• SINOTRUK HOWO 8×4 Dump Trucks — Mining and construction sites where low-speed, high-torque operation pushes oil temperatures to their limits.
• SINOTRUK SITRAK C7H Heavy-Duty Tractors — Premium fleet applications demanding maximum uptime and component reliability.
• SINOTRUK HOWO T7H Series — Mixed-use fleets operating across variable terrain and climate conditions.
• SINOTRUK HOWO Concrete Mixer Trucks — Continuous PTO-driven operation that places additional thermal stress on the lubrication system.

Whether your trucks are hauling containers across African highways, moving aggregate in Southeast Asian quarries, or delivering goods across Central Asian trade corridors, this oil cooler is built to handle the thermal demands your engines face daily.

3. Visual inspection for surface defects and brazing integrity
4. Packaging integrity check before dispatch

Bulk Order Advantages

As a factory-direct supplier, we offer tiered pricing for volume orders. Whether you need 10 units for a regional workshop or 500 units for a national distribution network, our supply chain scales to meet your demand with lead times as short as 3–7 business days for stocked items.

Frequently Asked Questions

How do I confirm that VG1246070012 is the correct oil cooler for my engine?

Cross-reference the part number stamped on your existing oil cooler housing. VG1246070012 fits SINOTRUK engines in the WD615 and D12 family. If your current cooler shows a different suffix, send us a photo and your engine nameplate data — our technical team will confirm compatibility within 24 hours.

What are the signs that my oil cooler needs replacement?

Watch for these warning indicators: milky discoloration in your coolant (oil contamination), unexplained coolant loss, elevated oil temperature readings above 120°C under normal load, or visible external oil seepage around the cooler housing gaskets. Any of these symptoms suggest internal seal failure or core perforation.

Is this oil cooler identical to the original factory-installed part?

Yes. This unit is manufactured to the same dimensional tolerances, material specifications, and performance parameters as the original equipment part. It uses the same mounting bolt pattern, port thread size, and flow capacity — ensuring a seamless drop-in replacement without any adapter fittings or bracket modifications.

Can I use this oil cooler with non-OEM coolant or oil?

The cooler is compatible with standard heavy-duty engine oils (CI-4 / CJ-4 grade) and ethylene glycol-based coolants. We recommend following SINOTRUK’s specified oil and coolant grades to maximize seal longevity and heat transfer efficiency. Avoid mixing coolant types, as chemical incompatibility can accelerate internal corrosion.

What is the expected lifespan of this oil cooler?

Under normal operating conditions with proper coolant maintenance, this oil cooler delivers reliable performance for 200,000 to 300,000 km. Harsh operating environments (extreme dust, corrosive water, or frequent thermal cycling) may reduce this interval. We recommend inspecting the cooler during every major service interval.

Do you ship internationally, and how is the part protected during transit?

We ship worldwide via sea freight, air freight, and express courier. Each oil cooler is individually boxed with foam cushioning and moisture-barrier wrapping to prevent damage and corrosion during ocean transit. For bulk orders, we palletize and shrink-wrap shipments for added protection.
