What does the charge air cooler do on a Komatsu wheel loader?

The charge air cooler, also called an intercooler, cools the compressed intake air from the turbocharger before it enters the engine. Cooler intake air helps maintain power output and protects engine components during heavy load cycles. That makes it an important part on turbocharged Komatsu wheel loaders like the WA380, WA470, WA480, WA600 and WA800.

Are Komatsu wheel loader charge air coolers new or rebuilt?

The charge air coolers we carry for Komatsu wheel loaders are new replacement units. Depending on the model, the core is either a bar-and-plate or a tube-and-fin design, so make sure the cooler you order is matched to your specific loader.
