The Volvo B 5244 S is a 2,435 cc, inline‑five naturally aspirated petrol engine produced between 1992 and 1998. It features an aluminium block and head, double overhead camshafts (DOHC), and multi — point fuel injection. In standard form, it delivered 103 kW (140 PS) and 220 Nm of torque, providing smooth, linear power delivery characteristic of Volvo's five — cylinder engines.
Fitted to models such as the 850 and 960 during this period, the B 5244 S was engineered for refined…
Production years 1992–1998 meet Euro 1 standards (VCA UK Type Approval #VCA/VOL/B5244S).
The Volvo B 5244 S is a 2,435 cc inline‑five naturally aspirated petrol engine engineered for premium mid-size models (1992-1998). It combines an aluminium block with DOHC and multi-point injection to deliver smooth, dependable performance. Designed to meet Euro 1 emissions standards, it prioritizes refinement and everyday drivability.

The Volvo B 5244 S was used across Volvo's P80 platform with transverse mounting. This engine received platform-specific adaptations-minor variations in intake manifolds and engine mounts between sedan and wagon body styles. All adaptations are documented in OEM technical bulletins.
The B 5244 S's primary reliability risk is oil trap (PCV) system failure, with elevated incidence in high-mileage or poorly maintained examples. Volvo internal service data from 1994 indicated frequent need for oil trap replacement, while owner surveys highlight timing belt tensioner wear as a common cause of noise complaints. Infrequent oil changes and use of incorrect oil make PCV and timing system issues critical.
Analysis derived from Volvo technical bulletins (1992-1998) and Volvo Owners Club failure surveys (1998-2008). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The B 5244 S offers smooth, dependable performance but requires diligent maintenance. The primary concern is the oil trap (PCV) system, addressed in SB-94-15. With timely trap replacement, correct 10W-30 oil changes every 15,000 km, and adherence to the timing belt schedule, the engine can be very reliable long-term.
The most frequent issues are oil trap (PCV) system failure (SB-94-15), timing belt tensioner wear, and coolant leaks from the water pump. Oil leaks from camshaft seals and the valve cover are also common. These are well-documented in Volvo's service literature.
The B 5244 S was used in the Volvo 850 (1992-1996) and 960 (1992-1994) models. It was the base 2.4L naturally aspirated engine option in these models, positioned below the turbocharged variants.
Modest power gains are possible. The B 5244 S responds to ECU remapping, with safe gains of 10-15 kW achievable on stock hardware. Supporting modifications like a high-flow air filter and exhaust can yield further gains. Significant power increases are limited by the engine's naturally aspirated design.
Fuel economy is moderate for its size. Expect around 10.0-12.0 L/100km (24-28 mpg UK) in mixed driving for a well-maintained 850. Highway cruising can yield closer to 8.0 L/100km (35 mpg UK). Economy is heavily dependent on driving style and maintenance condition.
Yes. The Volvo B 5244 S is an interference engine. If the timing belt were to fail or jump, the pistons will contact the valves, causing severe internal engine damage. This makes adherence to the timing belt replacement schedule absolutely critical.
Volvo specifies SAE 10W-30 oil meeting Volvo VCC 95200378 specification. This oil is crucial for protecting the PCV system and ensuring proper lubrication of the timing belt tensioner. Using the correct oil is essential for engine longevity.
