The Volvo B 5244 S4 is a 2,435 cc, inline‑five petrol engine produced between 1998 and 2002. It features a cast‑iron block, aluminium head, dual overhead camshafts (DOHC), and Bosch Motronic 4.4 electronic fuel injection. In standard tune for the S70/V70, it delivered approximately 103 kW (140 PS), providing smooth, linear power for Volvo's mid — size models.
Fitted primarily to the Volvo S70 and V70 (P80 platform), the B 5244 S4 was engineered for refined, comfortable cru…

Production years 1998–2002 meet Euro 3 emissions standards (Swedish Transport Agency Type Approval Records).
The Volvo B 5244 S4 is a 2,435 cc inline‑five petrol engine engineered for mid-size sedans and wagons (1998-2002). It combines a robust cast‑iron block with a DOHC valvetrain and Bosch Motronic 4.4 electronic fuel injection to deliver smooth, predictable power. Designed to meet Euro 3 emissions regulations, it balances everyday drivability with modern emissions control.

The Volvo B 5244 S4 was used across Volvo's S70/V70 platforms with transverse mounting. This engine was part of the modular B5 family and shared many components with the B5234 variants. Minor ECU revisions were implemented during its production run, but no major facelifts created significant interchange limits for core mechanical parts. All adaptations are documented in OEM technical bulletins.
The B 5244 S4's primary long-term concern is failure of the oil trap in the PCV system, leading to excessive oil consumption and leaks. Volvo TSB-99-05 documented this as a cause of sludge buildup and damaged seals. Consistent operation and prompt replacement of the PCV system components are critical for preventing costly internal damage and external leaks.

The most common questions about engine codes, what they mean, how to find them and how this database works
The B 5244 S4 can be reliable long-term if its critical maintenance items are strictly followed: replacing the timing belt every 80,000-100,000 km and addressing PCV system failures per TSB-99-05. Neglecting the PCV system is the most common cause of oil leaks and consumption. With proper care, these engines can reach 250,000 km or more.
The most common and serious issues are PCV oil trap failure causing excessive oil consumption (TSB-99-05) and timing belt failure due to missed replacement intervals. Other common problems include coolant leaks from aging plastic components and oil leaks from seals. These are well-documented in Volvo's service literature.
The B 5244 S4 was fitted to the Volvo S70 sedan and V70 wagon from 1998 to 2000. It was used in the GLT and SE trim levels, positioned as the naturally aspirated 2.4L option below the turbocharged 2.3L and 2.4L variants.
Yes, within limits. Common upgrades include a performance exhaust, intake, and ECU remap. Significant power gains are difficult due to the engine's high compression ratio and naturally aspirated design, but drivability can be improved. Any tuning should be done cautiously to avoid overstressing the internals.
Fuel economy is moderate for its displacement. Expect figures around 10-12 L/100km (23-28 mpg UK) in mixed driving for a well-maintained car. Economy is heavily influenced by driving style, tire pressure, and the condition of the engine and transmission.
Yes. The Volvo B 5244 S4 is an interference engine. If the timing belt breaks or jumps, the pistons will contact the valves, causing severe internal damage that often requires a complete engine rebuild or replacement.
The engine requires SAE 5W-30 full synthetic oil meeting Volvo specification. This is critical for protecting the valvetrain and preventing sludge buildup. Using the correct oil and adhering to 10,000 km change intervals is essential for longevity, especially to mitigate PCV-related issues.
