The Volvo B 4164 S is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 1991 and 1995. It featured a dual overhead camshaft (DOHC) design with an aluminum cylinder head, representing Volvo's modern 16 — valve architecture. Output ranged from 85 kW (115 PS) to 90 kW (122 PS), with torque figures around 140–142 Nm, providing responsive performance for compact models.
Fitted primarily to the Volvo 440/460 and 480, the B 4164 S was engineered for agile,…
Production years 1991–1995 meet Euro 1 standards (EU Regulation (EC) No 715/2007 historical annex).
The Volvo B 4164 S is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for compact hatchbacks and coupes (1991-1995). It combines a dual overhead camshaft (DOHC) 16-valve design with multi-point fuel injection to deliver responsive, rev-happy performance. Designed to meet Euro 1 emissions standards, it relies on electronic engine management and catalytic converters for compliance.

The Volvo B 4164 S was used across Volvo's 400 platform with transverse mounting. This engine received minor updates during its production run, including revised camshaft materials and updated ECU maps. All adaptations 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 S's primary long-term reliability risk is intake camshaft lobe wear, particularly in units with poor maintenance history. While formal failure statistics are unavailable for this vintage, enthusiast club data and workshop reports consistently cite cam wear, timing belt neglect, and fuel injection 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 (1991-1995) and aggregated data from Volvo enthusiast clubs and specialist workshops. Repair procedures should follow manufacturer guidelines where available.
The most common questions about engine codes, what they mean, how to find them and how this database works
The B 4164 S is renowned for its smooth, high-revving character and robust design, making it fundamentally reliable if well-maintained. Its main vulnerability is intake camshaft lobe wear, which can be prevented with strict adherence to oil change intervals and using the correct specification. With diligent servicing, these engines can run reliably for hundreds of thousands of kilometers.
The most frequent issues are intake camshaft lobe wear (often from poor oil maintenance), timing belt failure (from neglecting replacement intervals), fuel injection system faults (clogged injectors, sensor failures), and oil leaks from aged gaskets/seals. These are well-documented in vintage Volvo service literature and bulletins.
The B 4164 S engine was used in the Volvo 440, 460, and 480 from 1991 until 1995. It was eventually replaced by more advanced engine families in Volvo's subsequent compact models.
Yes, within limits. Common upgrades include fitting a higher-flow exhaust system, a performance air filter, and a remapped ECU. More aggressive camshafts are also available. Significant power gains are possible, but the engine's age and the cost of parts should be considered.
Fuel economy is good by period standards. Expect figures around 8-10 L/100km (28-35 mpg UK) in mixed driving for a car like the 440. This can vary significantly based on driving style, vehicle condition, and tire choice.
Yes. The Volvo B 4164 S is an interference engine. If the timing belt fails, the pistons will contact the valves, causing severe internal engine damage. This makes strict adherence to the 60,000 km replacement interval absolutely critical.
For original specification, a high-quality synthetic or semi-synthetic oil like SAE 5W-30 meeting API SH/SG standards is essential to protect the camshafts as per Service Bulletin #4164S-01. Modern equivalents meeting ACEA A3/B4 are also suitable.
