3.6L Pentastar Engine Options

Your option depends on your engine code. Have your full 17-character VIN ready and our team will confirm it.

Which option do I need? ERB code → Option 1 or 2 (Option 4 for 2012–2017 Wrangler JK). ERC, ERG or ERF code → Option 3.

Vehicle Fitments and Engine Codes (ERB / ERC / ERF)

Pentastar fitment varies by VIN, emissions package, drivetrain, oil cooler configuration, transmission pairing and model year. Common ERB, ERC and ERF applications span Chrysler, Dodge, Jeep and Ram from 2011 to present. Always confirm final fitment by VIN before ordering.

Note: the 2014-and-newer Jeep Cherokee (KL) V6 is the smaller 3.2L Pentastar, not the 3.6L. Have your full 17-character VIN ready and our team will confirm the engine code.

Common 3.6L Pentastar Engine Problems

Strong horsepower, fuel economy and broad application coverage, but several well-known failure points across Jeep, Dodge, Chrysler and Ram platforms. Most owners start searching for a replacement after repeated top-end noise, overheating, oil leaks or valvetrain failure.

Repair or Replace? Signs You Need a 3.6L Pentastar

Some Pentastar problems start as small drivability issues before progressing into major internal damage. Many customers contact Fraser after repeated repairs fail to permanently solve ticking noise, overheating, oil leaks or top-end failure.

• Ticking or tapping noise from the top end
• Persistent misfires or cylinder-specific codes
• Oil cooler housing leaks or coolant contamination
• Overheating or repeated coolant loss
• Low compression or failed leak-down test
• Timing-related noise or drivability issues
• Internal noise, oil starvation or bearing failure
• Replacement recommended by a licensed repair shop

We Don't Just Rebuild Pentastars. We Correct Factory Flaws.

Rocker arm failure, camshaft wear, cylinder head issues, oil consumption and timing wear are exactly why a used engine or basic rebuild is risky: without addressing these weaknesses, failure happens again. Fraser Advantage™ 3.6L builds reinforce the weak points for long-term reliability.

2. Upgraded valvetrain components. Addresses rocker arm and camshaft failure.
3. Precision machining. Restores the engine to zero-mile tolerances.
4. Improved oiling system. Reduces premature wear.
5. New pistons, rings and bearings. Ensures long engine life.

7. New timing components and oil pump. Durability and lubrication.
8. Fully tested and inspected. Every unit verified before shipping.

A Better Alternative to Another Used Pentastar Engine

A used Pentastar may already have hidden rocker arm wear, oil cooler problems, overheating history or internal damage, and the same factory defects that killed your original. Fraser remanufactured 3.6L engines are professionally renewed with updated Pentastar corrections applied where applicable.

• Zero-mileage build, not a questionable salvage engine
• Updated Pentastar wear components
• Professionally remanufactured block and cylinder heads
• Direct-replacement fitment for Jeep, Dodge, Chrysler and Ram
• Powertrain specialists: engines and transmissions every day
• VIN-based quotes to identify the correct engine code
• Shipping to commercial repair shops for easy unloading
• Core return assistance with pickup after install

Used Pentastar vs. Low-Cost Rebuild vs. Fraser Remanufactured

Many used Pentastars already have hidden rocker arm wear, oil cooler problems, overheating history or valvetrain damage you can't see during installation. Instead of gambling on another high-mileage used engine, you receive a professionally renewed replacement backed by Fraser's powertrain-focused support.

Protected Even in Situations Other Companies Would Deny

Fraser handles warranty claims directly with engine specialists, not call-center reps. Labor is reimbursed using Mitchell or ALLDATA book time.

Optional No-Fault upgrades from 1 to 5 years are available on every option. Coverage, labor reimbursement, eligibility, exclusions and claim procedures are governed by Fraser Engines' written warranty agreement.
