The Jeep 552 63 088 is a 2,987 cc, 60 — degree V6 turbo — diesel engine produced between 2011 and 2018. It was developed by Fiat Powertrain Technologies for global Jeep applications, featuring a DOHC 24 — valve layout, common rail direct injection, and a variable geometry turbocharger (VGT). In standard form it delivered 177 kW (241 PS) and 550 Nm of torque, providing strong, flexible pulling power ideal for larger SUVs.

Production years 2011–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 compliance depending on market .
The Jeep 552 63 088 is a 2,987 cc V6 turbo-diesel engineered for large SUVs and off-road vehicles (2011–2018). It combines common-rail direct injection with a single variable-geometry turbocharger to deliver high torque and refined cruising capability. Designed to meet Euro 5 (and later Euro 6) standards, it balances heavy-duty performance with emissions control.

The Jeep 552 63 088 – Diesel (Fiat Powertrain) was used across Jeep's WK2 platform with longitudinal mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-reinforced engine mounts in the Grand Cherokee and a specific exhaust routing for the Commander-and from 2015 the emissions system was updated for Euro 6 compliance, creating minor software and hardware interchange limits. All adaptations are documented in OEM technical bulletins.
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.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 63 088 offers strong performance and refinement, but its long-term reliability is heavily dependent on using the correct fuel and oil. The high-pressure fuel pump is a known weak point in early models. Vehicles with a full service history using Fiat-spec fluids and fuels can be very durable, often exceeding 200,000 km with proper care.
The most frequent issues are high-pressure fuel pump failure, clogging of the EGR valve and cooler, turbocharger actuator faults, and leaks from the oil cooler gasket. These are well-documented in Fiat Powertrain service bulletins and are often linked to maintenance practices or fuel quality.
This engine was primarily used in the Jeep Grand Cherokee (WK2) from 2011 to 2018. It was also fitted to the Jeep Commander (XK) in select international markets from 2011 to 2013. It was marketed as the '3.0L CRD' diesel engine in these vehicles.
Aftermarket ECU tuning is common on the 552_63_088 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is respectable for a large V6 diesel SUV. Expect combined figures of approximately 8.5–9.5 L/100km (30–33 mpg UK) for the Grand Cherokee. Real-world consumption will vary significantly based on driving style, load, and terrain, with highway driving yielding the best results.
Yes. This is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is robust and designed to last the engine's lifetime with proper oil maintenance.
Fiat Powertrain mandates the use of Fiat 9.55535-S1 specification oil, typically a 5W-40 synthetic. This specific formulation is critical for protecting the high-pressure fuel pump and turbocharger. Using non-approved oil can lead to premature component failure and is not covered under warranty.
