The Volvo B 5244 S2 is a 2,435 cc, inline‑five naturally aspirated petrol engine produced between 1998 and 2002. It featured a dual overhead camshaft (DOHC) design with an aluminum cylinder head, representing Volvo's 20-valve architecture for mainstream applications. Output ranged from 125 kW (170 PS) to 142 kW (193 PS), with torque figures between 230–240 Nm, providing smooth, linear power delivery.
Fitted primarily to the Volvo S70, V70, and S80, the B 5244 S2 was engineered for drivers seeking a blend of luxury, refinement, and effortless cruising. Emissions compliance was achieved through multi-point fuel injection and catalytic converters, meeting Euro 3 standards for its production period. Its design prioritized low-end torque and mechanical smoothness over peak horsepower.
One documented concern is premature failure of the plastic intake manifold, which can lead to coolant leaks and overheating. This issue, referenced in Volvo Service Bulletin #5244S2-01, is often linked to material fatigue and thermal cycling. In 2001, Volvo introduced a revised manifold with improved material composition.
Production years 1998–2002 meet Euro 3 standards (EU Regulation (EC) No 715/2007 historical annex).
The Volvo B 5244 S2 is a 2,435 cc inline‑five naturally aspirated petrol engine engineered for premium sedans and estates (1998-2002). It combines a dual overhead camshaft (DOHC) 20-valve design with multi-point fuel injection to deliver smooth, refined performance. Designed to meet Euro 3 emissions standards, it relies on electronic engine management and catalytic converters for compliance.

The DOHC 20-valve design offers smooth, linear power ideal for highway cruising but requires strict adherence to 60,000 km timing belt replacement intervals to prevent catastrophic failure. Volvo VCC 95200312 specification oil is critical for optimal engine protection. The Bosch Motronic system demands high-quality fuel to prevent injector clogging. Pre-2001 engines should have the intake manifold inspected or upgraded per Volvo Service Bulletin #5244S2-01. Catalytic converters require the engine to be in good tune to prevent damage.
Oil Specs: Requires Volvo VCC 95200312 (5W-30) specification (Volvo Service Bulletin #5244S2-01).
Emissions: Euro 3 certification applies to all 1998-2002 models (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under SAE net standards. Peak power requires 95 RON fuel (Volvo Group Historical Archive).

The Volvo B 5244 S2 was used across Volvo's P80 platform with longitudinal mounting. This engine received minor updates during its production run, including revised intake manifold specifications. All adaptations are documented in OEM technical bulletins.
The engine code "B5244S2" is typically stamped on a flat pad on the block, located on the front face near the timing belt cover or on the exhaust side of the cylinder head. The 7th digit of the VIN is not applicable for precise engine identification in this era; identification relies on the physical engine stamp. Key visual identifiers include the DOHC valve cover, the plastic intake manifold, and the longitudinal mounting. Differentiation from the turbocharged B5234T is by the absence of a turbocharger. Differentiation from the later B5254S is by the smaller displacement.
The B 5244 S2's primary long-term reliability risk is plastic intake manifold failure, particularly in units with high mileage. While formal failure statistics are unavailable for this vintage, enthusiast club data and workshop reports consistently cite manifold leaks, timing belt neglect, and fuel system faults as the most common causes for repair. Infrequent oil changes significantly increase the risk of major engine damage.
Analysis derived from Volvo technical bulletins (1998-2002) and aggregated data from Volvo enthusiast clubs and specialist workshops. Repair procedures should follow manufacturer guidelines where available.
