Problems That Require a Complete Engine Replacement 

Depending on the severity of the issue, engine replacement may be the only viable option for getting your vehicle back on the road.

  • Extensive rust and corrosion
  • Damage and wear from frequent use 
  • Extreme overheating caused by a lack of coolant circulation
  • Components in the block or the head that have worn out significantly
  • Components that are severely worn out in the block or the head

Our trained technicians will do everything they can to diagnose and repair the engine. If we believe that replacing your vehicle’s engine is the safest option, we will install a brand-new, high-quality unit backed by our nationwide guarantee that is good for three years or 36,000 miles.
