Pure Mack Engine Overhaul

If your engine’s performance isn’t what it used to be, it could be time for an overhaul. And nobody knows how to breathe new life into your engine better than the people who built it in the first place.

Six Signs That It's Time for an Overhaul

The road can be rough—and make tough demands of your truck over the long haul. How do you know whether your engine needs an overhaul? If it's exhibiting any of the following symptoms, it’s probably time for some serious service.

  • Hard braking/reduced acceleration

  • Blue, black or white exhaust

  • Engine knocking

  • Increased oil consumption

  • Poor engine braking

  • Low fuel economy or oil pressure
