FAQ Hydraulic Oil Cooler 203-03-41380 for Komatsu PC100 PC120

What machines is the 203-03-41380 hydraulic oil cooler compatible with?

It is a direct fit for Komatsu PC100-3, PC120-3, PC120-3U, PC100L-3, PC150-3 and related models widely used in the mid-size excavator range.

How does the large 713x575mm size and dense core provide better performance?

The significantly larger cooling surface and high-density plate-fin design offer superior heat exchange efficiency compared to standard aftermarket or worn original coolers, resulting in lower operating temperatures and more stable hydraulic performance.

What is the minimum order quantity and lead time for the 203-03-41380?

Our standard MOQ is 20 units with a typical production lead time of 60 days. We support mixed container shipments with other Komatsu cooling components.

Why should professional distributors choose this aftermarket 203-03-41380 cooler?

It outperforms many competing replacements with reinforced construction, larger core size, and better heat dissipation, delivering longer service life, fewer failures, and higher customer satisfaction.

How does the 203-03-41380 hydraulic oil cooler improve excavator operation?

It maintains lower and more stable hydraulic oil temperatures, reducing oil thinning, seal damage, valve sticking, and power loss — especially important for PC100-3 and PC120-3 working in high ambient temperatures or heavy-duty cycles.
