The Jeep 552 63 624 is a 3,604 cc, 60-degree V6 naturally aspirated petrol engine produced between 2015 and 2020. Developed by Fiat Powertrain, it features dual overhead camshafts (DOHC), variable valve timing (VVT), and sequential multi-port fuel injection. In standard form, it delivers 210 kW (285 PS) and 353 Nm of torque, providing a smooth, linear powerband ideal for highway cruising and moderate off-road use.
Fitted primarily to the WK2 Grand Cherokee and occasionally the Commander, this engine was engineered for drivers seeking refined performance and everyday drivability. Emissions compliance was achieved through precise VVT control and a close-coupled three-way catalytic converter system, meeting Euro 6 standards across its entire production run.
One documented concern is premature failure of the plastic intake manifold, which can crack near the throttle body mounting flange, leading to unmetered air leaks and lean running conditions. This issue, highlighted in FCA Technical Service Bulletin 09-015-17, is attributed to material brittleness under sustained thermal cycling. Revised manifolds made from a more heat-resistant polymer were introduced in mid-2018.
Production years 2015–2020 meet Euro 6 standards for all markets (VCA UK Type Approval #VCA/EMS/5679).
The Jeep 552 63 624 is a 3,604 cc V6 petrol engineered for SUVs and off-road vehicles (2015-2020). It combines DOHC architecture with variable valve timing to deliver smooth, responsive power and efficient cruising. Designed to meet Euro 6 standards, it balances performance with modern emissions control.

The naturally aspirated V6 provides predictable, linear power ideal for daily driving but requires strict adherence to 16,000 km oil change intervals using MS-6395 (5W-20) specification to protect chain guides and VVT solenoids. The plastic intake manifold is susceptible to cracking on early builds; units before 06/2018 should have the manifold upgraded preventatively per FCA TSB 09-015-17. The engine is sensitive to fuel quality; use of 95 RON (or higher) is recommended for optimal performance and emissions control.
Oil Specs: Requires FCA specification MS-6395 (5W-20) (FCA Owner's Manual). ACEA A5/B5 is not a sufficient substitute.
Emissions: Euro 6 certification applies to all models and years (VCA Type Approval #VCA/EMS/5679). No market-specific variations.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across all model applications (FCA TIS Doc. V6P-2015).

The Jeep 552 63 624 was used across Jeep's WK2 platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts for the Grand Cherokee SRT-and no significant facelift revisions, ensuring broad interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the left cylinder block, near the alternator (FCA TIS V6P-2015). The 8th VIN digit is 'C' for this petrol V6. Visually, it is distinguished by its cast aluminum intake manifold spanning both cylinder heads and the absence of a turbocharger. Critical differentiation from diesel V6s: The petrol unit lacks an EGR cooler and DPF. Service parts for the intake manifold are specific to production date; units before 06/2018 require the revised manifold (Part No. 68219875AB) per FCA TSB 09-015-17.
The 552 63 624's primary reliability risk is intake manifold cracking on early builds, with elevated incidence in hot climates or under sustained high load. FCA internal data indicated a notable failure rate before 80,000 km for pre-2018 units, while UK DVSA records note vacuum-related issues as a common MOT advisory. Sustained high under-hood temperatures make the preventative manifold upgrade critical.
Analysis derived from FCA technical bulletins (2015-2020) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
