Komatsu WA500-6 Intercooler Hose Description
YNF17033 intercooler air hose replaces Komatsu part number 425-03-33531, specifically designed for WA500-6 wheel loaders. This molded rubber pipe delivers compressed air from the turbocharger to the intercooler, enabling optimal cooling and efficient combustion. Constructed from heat- and oil-resistant EPDM rubber with reinforced textile layers, it resists cracking, swelling, and collapse under pressure or vibration. Precision-molded to fit the OEM layout, the hose ensures a leak-free seal and quick installation. It’s a reliable solution for turbocharged engine systems operating in demanding construction or quarry environments.

Knowledge Base
Intercooler hoses like 425-03-33531 are crucial in maintaining air pressure and engine efficiency. Over time, exposure to heat, oil mist, and vibration may degrade rubber integrity. Proactive replacement with YNF-grade hoses prevents boost loss and engine derate in high-performance wheel loaders.
