Advantages and Features


When it comes to making the engine installation process smoother, look to the Cat C32. Using innovative technology solutions, the C32 eliminates the need for diesel exhaust fluid (DEF) and reduces the size of the overall engine package. The DOC-only aftertreatment does not require regeneration and is maintenance free until a major engine overhaul.

Fully configurable engine with exceptional power density, a cooling package designed and backed by Caterpillar, plus a simplified engine mounted aftertreatment all help minimize total package size, simplify installation, and provide you with the quality deserve.
