C15 2004 Engine

The Cat® C15 on-highway engine comes packed with the power, performance and reliability Cat owners have come to expect and soon it can be spec'd with 600 or 625 horsepower. As the leading choice for owner-operators, fleets and heavy haulers who want high horsepower performance combined with unmatched durability and superior resale value, the C15 delivers.
Built to last with series turbochargers, a higher compression ratio, and higher cylinder pressure to produce improved performance, better throttle response and increased fuel economy. And like all heavy duty engines with ACERT technology, the C15 also features rugged components such as steel single-piece low friction pistons, four-bolt connecting rods and a high-efficiency water pump.
With peak torque ratings up to 2050 lb-ft, the C15 provides excellent startability and exceptional hill-climbing capability. And even with 625 horses under the hood, you can still expect low maintenance costs and long engine life.
