The Volvo B 4164 T4 is a 1,587 cc, inline‑four petrol engine produced between 1998 and 2004. It features a cast‑iron block, dual overhead camshafts (DOHC), and a Mitsubishi TD04 turbocharger with an air — to — air intercooler. This forced — induction unit delivered approximately 160 hp (119 kW) and 155 lb‑ft (210 Nm) of torque, offering spirited performance in Volvo's compact lineup.

The Volvo B 4164 T4 is a 1,587 cc inline‑four petrol engine engineered for compact sedans and wagons (1998-2004). It combines a robust cast-iron block with a modern DOHC 16-valve valvetrain and timing belt to deliver turbocharged performance. Designed to meet Euro 3 emissions regulations, it incorporated catalytic converters and precise electronic fuel injection.

The Volvo B 4164 T4 was used across Volvo's S40 and V40 platforms with transverse mounting. This engine received no significant platform-specific adaptations between sedan and wagon variants, though turbocharger and intercooler piping layouts varied slightly. All applications are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The B 4164 T4's primary reliability risk is turbocharger oil feed line failure, with elevated incidence in high-mileage or heat-soaked engines. Volvo service data indicates this was a frequent cause of turbo failure, while owner club surveys highlight ignition coil and timing belt issues as secondary concerns. Infrequent maintenance and neglect make regular inspection and adherence to OEM service intervals critical.
Analysis derived from Volvo technical bulletins (1998-2004) and Volvo Owners Club failure statistics (2010-2023). 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 4164 T4 can be reliable long-term if its critical maintenance, especially the 60,000-mile timing belt replacement and regular inspection of the turbo oil feed line, is strictly adhered to. Neglecting the oil feed line can lead to expensive turbo failure. With proper care, including regular oil changes and cooling system maintenance, these engines are known to last well beyond 150,000 miles.
The most critical issue is turbocharger oil feed line failure. Other common problems include ignition coil failure (especially on cylinders 1 and 4), timing belt failure leading to valve damage, and cooling system leaks. These are well-documented in Volvo service manuals and bulletins.
The B 4164 T4 was used exclusively in the performance-oriented T4 variants of the first-generation Volvo S40 (1998-2004) and V40 (1998-2004) models. It was never fitted to base models or later generations, which used larger 2.0L or 2.4L engines.
Yes. Common upgrades include installing a manual boost controller to increase boost pressure, upgrading the exhaust system, and performing an ECU remap. These can yield significant power gains (20-40 hp). More extensive tuning requires internal modifications like forged pistons to handle increased pressure.
Fuel economy is moderate for a turbocharged engine. Expect around 24-28 mpg (imperial) in mixed driving for an S40 T4. Highway cruising can yield up to 34 mpg, while city driving may drop to 20 mpg. Aggressive driving will significantly reduce fuel economy.
Yes. The Volvo B 4164 T4 is an interference engine. If the timing belt fails, the pistons will collide with the open valves, causing severe internal damage that often requires a complete engine rebuild or replacement.
Volvo originally specified SAE 5W-30 semi-synthetic oil. A good quality 5W-30 meeting ACEA A3/B3 or A3/B4 specifications is still recommended for these engines. For high-mileage engines, a high-mileage formulation can help condition seals and reduce oil consumption.
