Product Advantages
Core strengths
Choose the hydraulic oil cooler that suits you best.
Precise Fit for CAT E320 Excavator
Specifically engineered for Caterpillar E320, 320, 320L, and related excavator models. All mounting interfaces, port dimensions, and bracket positions are identical to OEM specifications-enabling direct replacement with no modifications or adaptations required.
Optimized Flow Path, Low Resistance & High Flow
Internally designed oil passages maximize cooling efficiency while minimizing hydraulic oil flow resistance. Reduces energy loss and improves overall machine fuel economy.
Premium Aluminum Core, Lightweight & Durable
Constructed from high-strength aluminum alloy, offering excellent thermal conductivity, corrosion resistance, and significant weight savings. Each core undergoes rigorous pressure and leak testing to ensure no deformation or leakage under long-term heavy-load operation.
Reinforced Structure, Vibration & Impact Resistant
Features reinforced end plates and mounting brackets engineered to withstand the high-frequency vibration and shock loads typical of excavator operation. Ensures long-term, stable performance in harsh working conditions.

FAQ
Q:My E320 excavator frequently runs with high hydraulic oil temperature. Could this be caused by the cooler?
A: Possibly, but not necessarily the only cause. High oil temperature can result from multiple factors:
1) Clogged cooler fins (dust, mud);
2) Cooling fan failure or blocked airflow;
3) Excessive internal leakage in the hydraulic system (worn pump/valves);
4) Internal blockage or leakage in the cooler itself. We recommend first checking if the cooler surface is clean and the fan is operating properly, then using an infrared thermometer to measure the temperature difference between the cooler inlet and outlet. If cooler blockage or leakage is confirmed, this product is the ideal direct replacement.
Q:Is this cooler made of aluminum or copper?
A:This is a high-strength aluminum alloy cooler. Compared to traditional copper core coolers, aluminum offers advantages including lighter weight (approximately 40% reduction), excellent thermal conductivity, and superior corrosion resistance-making it the mainstream choice for modern construction equipment. The core is manufactured using vacuum brazing technology for high strength and reliable sealing.
Q:What is the most important consideration during installation?
A:System cleanliness and sealing are absolutely critical!
1) Thoroughly clean all oil line connections before installation to prevent contaminants from entering the hydraulic system;
2) Replace O-rings or gaskets with new ones to ensure leak-free connections;
3) Use a torque wrench and tighten to specified torque to prevent overtightening (which can damage threads) or undertightening (which can cause leaks);
4) After installation, start the engine and cycle all hydraulic functions to bleed air, then inspect all connections for leaks.
Q:How can I confirm this cooler fits my 320 excavator?
A:The most accurate method is to check the part number label on your original cooler and verify it is 7Y-1960. Alternatively, you can provide your excavator model and size of the oil cooler to us for final verification. The 320 series has multiple variants (320, 320L, 320N, etc.), and cooler configurations may vary slightly between them.
