The Volvo B4164S3 is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 1995 and 1998. It features a cast iron block, aluminum head, and dual overhead camshafts (DOHC) driven by a timing belt. This compact and efficient engine was engineered for Volvo's entry-level models, balancing fuel economy with adequate power for urban driving.
Fitted primarily to the Volvo S40 and V40 (first generation), the B4164S3 was designed for responsive, economical motoring with an emphasis on low emissions and reliability. Emissions compliance was managed through Bosch Motronic 4.3 electronic fuel injection and catalytic converters, meeting Euro 2 standards for its production era.
One documented service consideration is the susceptibility of the plastic intake manifold to cracking at the coolant passages, potentially leading to coolant leaks into the intake, as noted in Volvo Service Bulletin #SB-95-22. The engine was succeeded by the updated B4184S series with revised manifold design.
Production years 1995–1998 meet Euro 2 emissions standards (VCA UK Type Approval applicable for registered imports).
The Volvo B4164S3 is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for compact sedans and wagons (1995-1998). It combines a dual overhead camshaft design with Bosch Motronic fuel injection to deliver smooth, efficient power for daily commuting. Designed to meet Euro 2 emissions standards, it prioritizes mechanical simplicity and low running costs.

The DOHC 16-valve design provides a smooth, rev-happy power band ideal for city driving but requires strict adherence to the 80,000 km timing belt replacement interval to prevent catastrophic engine failure. SAE 5W-30 semi-synthetic oil is recommended for optimal cold-start protection and fuel efficiency. The plastic intake manifold is a known failure point; inspect for coolant leaks or cracks. The Bosch Motronic system is generally reliable but sensitive to sensor faults.
Oil Specs: Requires SAE 5W-30 specification (Volvo Owner's Manual 1996). Modern synthetics meeting ACEA A3/B3 are suitable.
Emissions: Certified to Euro 2 standards for all production years (1995-1998) (VCA UK Type Approval applicable for registered imports).
Power Ratings: Measured under SAE net horsepower standards (post-1972). Output is consistent across applications (Volvo Workshop Manual 1995).

The Volvo B4164S3 was used across Volvo's S40/V40 platform with transverse mounting. This engine received specific ECU calibrations for different trim levels, creating minor power variations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat pad atop the block, near the gearbox flange on the firewall side (Volvo Workshop Manual 1995). The casting number for the B4164S3 block is 'B4164'. Visual identification: Features a DOHC valve cover, Bosch Motronic ECU and wiring harness, and a distinctive plastic intake manifold with integrated coolant passages. Differentiate from the larger B4184S by its smaller displacement and earlier production date.
The B4164S3's primary reliability risk is coolant leakage from the plastic intake manifold, which can lead to hydrolock or internal corrosion if coolant enters the cylinders. Volvo service data from the mid-1990s indicates this was a frequent cause of warranty claims, particularly in vehicles subjected to frequent thermal cycling. Strict adherence to the 80,000 km timing belt schedule is also critical to prevent interference engine damage.
Analysis derived from Volvo technical bulletins (1995-1998) and workshop manuals (1995-1997). Repair procedures should follow manufacturer guidelines.
