Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
The engine code is essential for ordering parts, diagnosing issues, and verifying compatibility. It is not the same as the VIN or chassis number. This guide shows exactly where to find it - by model and engine type - using official Jeep and DVLA sources
A unique identifier (e.g., VM6, 30E, 57H) used for parts and service.
The vehicle identification number that holds encoded vehicle and engine information.
The chassis or frame number used for registration and legal identification.
Locate the engine code on the driver's side of the engine block, near the cylinder head. The VIN 8th character will be 'F' for Pentastar engines. Also check the engine cover label.
The engine code is located on a label attached to the valve cover. The VIN 8th character will be 'S' for EcoDiesel. Look for '3.0L EcoDiesel V6' marking.
Open the hood and look at the engine cover. The code GME-T4 or 'Hurricane' will be visible. VIN 8th character is 'U' for 2.0L turbo hybrid.
The engine code is cast into the side of the block near the distributor. Look for '4.0L' or '242 CID' markings. Classic AMC engine family.
Engine code locations per Jeep Service Manual. V5C field definitions from DVLA Guide to Vehicle Registration. VIN structure compliant with EU Regulation (EC) No 715/2007, Article 7.
A technical breakdown of Jeep's core engine systems including Pentastar V6, EcoDiesel, GME-T4 Hurricane turbo, and 4xe hybrid technology with documented reliability impacts. All data sourced from Stellantis Technical Service Information and EU Regulation (EC) No 715/2007
The 3.6L Pentastar V6 is Jeep's signature engine, introduced in 2010. It features dual overhead camshafts, variable valve timing (VVT), and produces 285-295 horsepower with excellent reliability.
The Pentastar uses aluminum construction, dual VVT on both intake and exhaust camshafts, and a maintenance-free timing chain. It features electronic fuel injection and can run on E85 flex fuel in some applications.
VM6 (2010)
285-295 HP, 260 lb-ft torque
VM6 + eTorque (2018)
Mild hybrid system added
VM6 (2021+)
Improved cooling, stop-start
Oil consumption
Some units consume oil between changes
Cylinder head issues
Early models (2011-2013) had head failures
Thermostat housing
Plastic housing can crack

The most common questions about engine codes, what they mean, how to find them and how this database works
Confirm the full engine designation using vehicle-specific manufacturer records and the engine marking. An engine serial number, a registration record and a marketed power badge are not automatically the same identifier. Match the VIN/build data and the installed engine before selecting parts or a replacement.
No. A factory-application reference and a replacement-interchange decision are different. Match the full engine designation, vehicle build data, emissions equipment, controls and relevant supplier/OEM information.
No. Records have different review states. Read the correction notice, source scope and application limits on the individual record. Missing technical fields must not be inferred from similar engine codes.
