The Volvo B 5244 T3 is a 2,435 cc, inline‑five turbocharged petrol engine produced between 1998 and 2005. It features a cast‑iron block, aluminum head, dual overhead camshafts (DOHC), and multi — point fuel injection. This unit delivered 147 kW (200 PS) and 285 Nm of torque, engineered for refined yet spirited performance in Volvo’s executive models.
Fitted to models such as the S60, V70, and XC90 (early T5 variants), the B 5244 T3 was designed for drivers seeking a balance of…
Production years 1998–2005 meet Euro 3 emissions standards (Swedish Transport Agency Type Approval #STV/B5244/1998).
The Volvo B 5244 T3 is a 2,435 cc inline‑five turbocharged petrol engine engineered for executive sedans, wagons, and SUVs (1998-2005). It combines a unique five-cylinder architecture with DOHC and a low-inertia turbocharger to deliver smooth, linear power. Designed to meet Euro 3 emissions standards, it balances responsive performance with everyday drivability.

The Volvo B 5244 T3 was used across Volvo's P2 platform with transverse mounting. This engine received minor ECU and emissions revisions over its lifespan, creating minor interchange limits for electronic components. All adaptations are documented in OEM technical bulletins.
The B 5244 T3's primary reliability risk is failure of the turbocharger control solenoid, as documented in Volvo TSB 3-01-009. This can lead to erratic boost pressure and reduced performance. While the engine's mechanical components are robust, neglecting the 60,000 km timing belt interval remains a critical secondary risk, though the non-interference design prevents catastrophic damage if it fails.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the B 5244 T3 is fundamentally reliable mechanically and can last 300,000+ km with proper care. Its main weaknesses are the turbocharger control solenoid (prone to electrical faults) and the timing belt, which must be replaced at 60,000 km. Otherwise, its robust design and over-engineered components provide excellent longevity for a performance engine.
The most common issues are turbocharger control solenoid failure (causing erratic boost), timing belt failure (if not replaced), oil leaks (turbo seals, valve cover), and ignition coil failure. These are all well-documented in Volvo service literature and are generally straightforward to fix.
The B 5244 T3 was used in the first-generation S60 (2000-2004), second-generation V70 (1998-2004), and the first-generation XC90 (2002-2005). It was marketed as the T5 engine, offering a balance of performance and refinement in Volvo's executive lineup.
Yes, significantly. The B5244T3 responds very well to ECU remapping and boost controller upgrades. Stage 1 tunes can reliably increase power to 240-260 PS and torque to 350+ Nm without any hardware modifications. More significant gains require upgraded turbos, intercoolers, and internal components.
Fuel economy is typical for a high-performance 2.4L turbo engine. Expect around 11-13 L/100km (21-25 mpg UK) in mixed driving for an S60 or XC90 T5. Highway cruising can yield closer to 8-9 L/100km (31-35 mpg UK), while aggressive driving will be much higher. Driving style heavily influences consumption.
No. The B 5244 T3 is a non-interference (free-running) engine. If the timing belt breaks, the pistons and valves will not collide, preventing catastrophic internal damage. This is a significant safety feature, though the engine will still stop running and require a new belt.
A good quality mineral or semi-synthetic oil meeting API SG/CC specifications is recommended. SAE 10W-40 is ideal for most climates. Modern equivalents to the original specification are readily available. Change oil every 10,000-15,000 km or annually.
