Common Symptoms of a Failing Ingenium Engine
Timing Chain Wear
The timing chain system on the Ingenium engine can experience premature wear under extended service intervals. Symptoms include cold-start rattles, timing fault codes, reduced performance, and potential engine damage if not addressed.
Oil Dilution & Lubrication Issues
Short-trip driving and extended oil change intervals can lead to fuel dilution in the oil, reducing lubrication effectiveness and increasing internal wear.
We recommend oil and filter changes every 5,000-7,000 miles using manufacturer-approved oil to maximize engine life.
Cooling System Concerns
Cooling system components such as plastic coolant fittings and housings may degrade over time, leading to leaks or overheating conditions.
We recommend inspecting and upgrading cooling system components during installation where applicable.
Warranty
Every remanufactured engine includes a 12-Month / 12,000-Mile Limited Warranty.
Extended warranty options are available.
Professional installation is required to maintain warranty coverage.
Core Return Program
A rebuildable engine core is required.
- No upfront core charge in most cases
- Core must be returned within 30 days
- Failure to return a rebuildable core will result in a $2,500 core charge
