Having problems with your Caterpillar C15? A new engine rebuild kit from Highway and Heavy Parts may be just what you need!
Your Caterpillar C15’s power and reliability start with the core parts deep inside the engine, where compression, cooling, and lubrication all come together. Over time, those internal components – pistons, liners, rings, and bearings – wear down and slowly lose their ability to seal, cool, and support the engine the way they should. Once that happens, you’ll start to see blow-by, oil consumption, fuel dilution, rising temperatures, and a noticeable drop in performance.
The longer those issues are ignored, the faster they snowball into bigger problems like scored liners, damaged pistons, or even a complete engine failure. That’s why a complete engine rebuild kit is so critical for a C15. Replacing everything at once restores the engine’s foundation, brings compression back to spec, and stops small issues from turning into expensive downtime.
