The Chrysler EXF is a 2,400 cc, inline‑four petrol engine produced between 2002 and 2004. It features sequential multi‑port fuel injection, a cast‑iron block, and a dual overhead camshaft (DOHC) valvetrain. This engine was designed as a refined, efficient powerplant for Chrysler's compact and midsize vehicles, delivering 150 hp (112 kW) and 162 lb‑ft (220 Nm) of torque.
Fitted primarily to the JR-platform minivans and PT Cruiser, the EXF was engineered for smooth, quiet operation and responsive performance in urban and highway driving. Emissions compliance for its production period was achieved through its electronic fuel injection and catalytic converter system, meeting the applicable US federal Tier 2 Bin 5 standards for light-duty vehicles.
One documented engineering update involved the oil pump pickup tube O-ring. Early 2002 production units used an O-ring material prone to hardening and cracking over time, potentially leading to oil pressure loss. Chrysler addressed this by revising the O-ring material specification for all production from mid-2002 onward, as detailed in Technical Service Bulletin 09-003-02.

The DOHC design provides smooth, refined power delivery ideal for passenger comfort but requires strict adherence to the 105,000-mile timing belt replacement interval to prevent catastrophic failure. The 9.5:1 compression ratio allows for reliable operation on regular unleaded fuel. Regular oil changes are critical to prevent sludge buildup, which can clog the oil pickup tube. Replacing the original O-ring (pre-mid-2002) with the revised material (Part No. 05017093AA) is a recommended preventative measure during timing belt service.
Oil Specs: Requires API SJ 5W-30 specification (Chrysler Owner's Manual 2002). API SN or SP 5W-30 is an acceptable backward-compatible replacement.
Emissions: US Federal Tier 2 Bin 5 certification applies to all 2002-2004 model year vehicles (EPA Certificate #A-02-08).
Power Ratings: Measured under SAE net standards (J1349). Ratings are for the base EXF configuration in minivan applications (Chrysler Powertrain Guide 2002).

The Chrysler EXF was used across Chrysler Corporation's JR and PT platforms with transverse mounting and was not licensed to other manufacturers. This engine received platform-specific adaptations-primarily related to accessory drive layouts and engine mounts for different body styles. All adaptations are documented in OEM technical bulletins.
The engine code "EXF" is stamped on a machined pad on the front of the cylinder block, near the timing cover (Chrysler Service Manual 81-270-0201). The 8th digit of the VIN will be "F" for vehicles equipped with this 2.4L DOHC engine. Visually, it can be identified by its cast-iron block, aluminum cylinder head with "2.4L DOHC" casting, and the timing belt cover on the front of the engine. It is distinct from the earlier SOHC 2.4L (code EDZ) by its DOHC head and different intake manifold.
The EXF's primary long-term reliability consideration is adherence to the timing belt replacement schedule. Internal Chrysler service data indicates that the majority of catastrophic engine failures are due to neglected timing belt changes, leading to valve and piston damage. The engine is otherwise robust, but sludge buildup from infrequent oil changes can lead to oil starvation and bearing failure. Strict maintenance is critical for longevity.
