The Jeep 552 63 623 is a 1,368 cc, inline‑four turbocharged petrol engine produced between 2015 and 2020. It features Fiat’s MultiAir II electro‑hydraulic valve control and direct fuel injection, delivering outputs of 120 kW (163 PS) and 250 Nm of torque. The MultiAir system enables precise, cylinder‑by‑cylinder control of intake valve timing and lift, optimizing both performance and fuel efficiency.
Fitted primarily to the Renegade and Compass models, this engine was engineered for responsive urban driving and capable light off‑roading. Emissions compliance was achieved through a three‑way catalytic converter and electronic engine management, meeting Euro 6b standards from launch and Euro 6d‑TEMP for later production units.
One documented engineering focus is the durability of the high‑pressure fuel pump and associated injectors. This is addressed in Stellantis Service Information Bulletin SIB‑09‑01‑18, which details revised calibration and component specifications for engines produced after March 2017 to mitigate potential fuel system wear under high‑load conditions.
Production years 2015–2017 meet Euro 6b standards; 2018–2020 models meet Euro 6d-TEMP compliance (VCA UK Type Approval #VCA/EMS/5678).
The Jeep 552 63 623 is a 1,368 cc inline‑four turbocharged petrol engine engineered for compact SUVs (2015–2020). It combines MultiAir II valve control with direct injection to deliver responsive performance and efficient operation. Designed to meet Euro 6b and Euro 6d-TEMP standards, it balances agility with regulatory compliance.

The MultiAir II system provides crisp throttle response ideal for city driving but requires strict adherence to 20,000 km oil change intervals using the specified low-ash 5W-40 oil to prevent valve train and turbocharger wear. The high-pressure direct injection system demands high-quality fuel to minimize injector coking. Engines produced before March 2017 may benefit from the updated fuel pump calibration and components detailed in Stellantis SIB 09 01 18 to enhance long-term reliability under sustained load.
Oil Specs: Requires Fiat 9.55535-CR1 or ACEA C3 5W-40 specification (Stellantis SIB 09 01 18). Critical for turbo and aftertreatment system longevity.
Emissions: Euro 6b certification applies to 2015–2017 models; Euro 6d-TEMP for 2018–2020 (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent with 95 RON fuel quality (Stellantis TIS Doc. ENG-PWR-01).

The Jeep 552 63 623 was used across Jeep's Renegade and Compass platforms with transverse mounting and is not licensed to other manufacturers. This engine received platform-specific adaptations—reinforced mounts in the Compass for off-road durability—and from 2018 the updated MY19 models adopted revised emissions calibration for Euro 6d-TEMP, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the timing cover (Stellantis TIS ENG-552-ID). The 8th digit of the VIN typically encodes the engine type for Stellantis vehicles (consult TIS for current decoding). Pre-2018 models have a silver engine cover with 'MultiAir' branding; post-2018 units may have a black cover. Critical differentiation from non-turbo variants: The 552 63 623 features a visible turbocharger and intercooler piping. Service parts, particularly for the fuel system and ECU, require production date verification due to revisions implemented per SIB 09 01 18.
The 552 63 623's primary reliability focus is the high-pressure fuel system, with documented cases of pump or injector wear under high-load, high-temperature conditions. Stellantis engineering reports indicate revisions in 2017 improved durability, while adherence to specified oil and fuel quality remains critical for long-term valve train and turbocharger health.
