EcoBoost Timing Chain Problem

The #1 issue with 3.5L EcoBoost engines: timing chain failures.

What happens:

  • Timing chain stretches or breaks
  • Engine loses timing, causing catastrophic damage
  • Pistons hit valves, destroying engine

Affected years:

  • 2011-2012 most common
  • 2013-2019 less frequent but still occurs

Symptoms:

  • Rattling noise on cold starts
  • Check engine light with timing codes
  • Loss of power
  • Sudden engine failure

Cost to fix (before failure):

  • Timing chain replacement: $2,000-$3,500

Cost if engine fails:

  • Engine replacement: $5,000-$10,000

Pro tip: When buying a used 3.5L EcoBoost, verify timing chains have been replaced or buy low-mileage (under 80,000 miles).

Should You Replace With the Same Explorer Engine?

Yes—always stick with your original Explorer engine type.

Why same-engine replacement is critical:

  • Computer systems are VIN-specific
  • Transmission calibrated for specific engine
  • AWD system programming matches engine
  • Emissions compliance
  • Maintains towing ratings

Engine swaps are expensive:

  • Custom wiring: $1,000-$2,500
  • ECM reprogramming: $1,000-$2,500
  • Transmission issues: $1,500-$4,000
  • Total: $4,000-$10,000+

What to Look for in a Used Explorer Engine

1. VIN Matching is Essential

Explorer engines vary by year, trim, AWD vs RWD, and emissions type.

2. Mileage Recommendations

  • 3.5L EcoBoost: Under 80,000 miles (timing chain concerns)
  • 3.5L NA V6: Under 100,000 miles
  • 2.3L EcoBoost: Under 60,000 miles (newer)

3. Timing Chain Status (3.5L EcoBoost)

Ask: Have timing chains been replaced? If yes, when and at what mileage?

4. Compression Testing

All cylinders within 10% of each other, readings within Ford specifications.

5. Warranty Coverage

Minimum 1-year, preferably 2-3 years.

Cost Comparison

Example: 2016 Explorer with 3.5L EcoBoost failure

New from Ford: $8,000-$11,000 total

Rebuilt: $5,500-$8,000 total

Used (Used Engines Store): $4,000-$6,500 total

Savings: $4,000-$4,500 vs new

Installation Considerations

What to replace:

  • Oil and filter
  • Coolant
  • Thermostat
  • Timing chains (if EcoBoost and not recently done)
  • Water pump
  • Spark plugs

Total parts: $400-$2,500 (depending on timing chain work)
