The Jeep 552 63 842 is a 3,604 cc, V6 naturally aspirated petrol engine produced between 2011 and 2013. It features a 60‑degree V6 layout, dual overhead camshafts, and variable valve timing (VVT) on both intake and exhaust camshafts. This powertrain delivers 210 kW (285 PS) and 353 Nm of torque, with its high redline and linear power delivery engineered for responsive on-road performance.
Fitted exclusively to the Grand Cherokee (WK2) in markets like Europe and Australia, the 552 63 842 was designed for drivers seeking a smooth, powerful alternative to diesel options. Emissions compliance for its production run was achieved through precise fuel injection and efficient combustion, meeting the Euro 5 standard.
One documented engineering focus was optimizing the variable valve timing system for low‑end torque and high‑rpm power, as outlined in Fiat Powertrain Engineering Bulletin FP‑PENT‑02. This involved specific calibration of the oil control solenoids and cam phasers. The engine was succeeded by the updated Pentastar variant with improved fuel economy and emissions.
All production years (2011–2013) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/9876).
The Jeep 552 63 842 is a 3,604 cc V6 naturally aspirated petrol engine engineered for flagship SUVs (2011-2013). It combines dual overhead camshafts with variable valve timing on both intake and exhaust to deliver smooth, linear power. Designed to meet Euro 5 standards, it balances strong performance with regulatory compliance.

The naturally aspirated V6 provides smooth, predictable power ideal for highway cruising but requires strict adherence to 12,500 km oil change intervals to protect the variable valve timing (VVT) system. Stellantis MS-6395 (5W-20) oil is critical for optimal VVT solenoid operation and fuel economy. The engine requires premium unleaded petrol (95 RON minimum) for optimal performance and to prevent knocking. The timing chain is designed for the engine's lifetime, but oil degradation can accelerate wear on the tensioners and guides. Software updates for emissions and drivability are available via dealership diagnostics.
Oil Specs: Requires Stellantis MS-6395 (5W-20) specification (Stellantis SIB 11 03 22).
Emissions: Euro 5 certification applies to all model years (VCA Type Approval #VCA/EMS/9876).
Power Ratings: Measured under SAE J1349 standards (Stellantis TIS Doc. TGC-5530).

The Jeep 552 63 842 was developed by Fiat Powertrain for Jeep's WK2 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts and a unique intake manifold runner for the Grand Cherokee. All adaptations are documented in OEM technical bulletins.
Locate the engine code “552 63 842” stamped on a machined pad on the left (driver’s side) bank of the engine block, near the front (Stellantis TIS TGC-5522). The 8th digit of the VIN is “R” for this petrol V6 model. Visually, the engine is identifiable by its V6 configuration, plastic intake manifold with “Pentastar” branding, and lack of a turbocharger or intercooler. Critical differentiation from the later 3.6L Pentastar: This early version has a different intake manifold design and VVT calibration. Service parts, particularly for the VVT system and intake, are specific to this engine code and model year.
The 552 63 842's primary reliability focus is on the variable valve timing (VVT) solenoids, with elevated failure rates noted in high-mileage vehicles where oil changes were extended. Stellantis internal data indicates this is a common cause of check engine lights, while UK DVSA records show minimal MOT failures related to the engine. Using the correct oil viscosity and adhering to service intervals are critical preventative measures.
Analysis derived from Stellantis technical bulletins (2011-2013) and UK DVSA failure statistics (2018-2024). Repair procedures should follow manufacturer guidelines.
