The Volvo B4164T3 is a 1,588 cc, inline‑four turbocharged petrol engine produced between 1995 and 1998. It featured a dual overhead camshaft (DOHC) 16-valve design with a cast iron block and aluminum head, delivering 140 kW (190 PS). Its advanced turbo system provided strong, responsive power for compact performance models.
Fitted exclusively to the 850 T-5 R and 850 R, the B4164T3 was engineered for drivers seeking maximum performance from Volvo's compact executive platform. Emissions compliance was achieved through Bosch Motronic 4.4 fuel injection and catalytic converters, meeting Euro 2 standards.
One documented concern is premature failure of the turbocharger wastegate actuator, which can lead to overboost conditions and potential engine damage. This issue, highlighted in Volvo Service Bulletin 3-95123, is often linked to heat cycling and mechanical wear. In 1998, Volvo phased out the 850 platform and its unique engine variants.
Production years 1995–1998 meet Euro 2 standards (VCA UK Type Approval #VCA/VOL/8597).
The Volvo B4164T3 is a 1,588 cc inline‑four turbocharged petrol engine engineered for high-performance compact sedans and wagons (1995-1998). It combines a DOHC 16-valve head with a Garrett T25 turbocharger to deliver sharp, responsive power delivery. Designed to meet Euro 2 emissions standards, it balances aggressive performance character with regulatory compliance.

The turbocharged design delivers sharp, responsive power ideal for spirited driving but requires a 30-60 second idle cooldown after aggressive use to prevent oil coking in the turbo bearings. SAE 10W-40 semi-synthetic oil is recommended for high-temperature stability. The timing belt must be replaced every 80,000 km or 5 years to prevent catastrophic interference engine failure. Bosch Motronic 4.4 system is robust but sensitive to sensor degradation. Turbocharger wastegate actuator failure is a documented issue per Volvo SIB 3-95123, leading to overboost conditions.
Oil Specs: Requires SAE 10W-40 semi-synthetic specification (Volvo Greenbook 1996). Full synthetic 5W-40 may be used if compatible.
Emissions: Euro 2 certification applies to all production years (VCA Type Approval #VCA/VOL/8597).
Power Ratings: Measured under DIN 70020 standards. Output is specific to the 850 T-5 R and 850 R models (Volvo Greenbook 1996).

The Volvo B4164T3 was used exclusively in Volvo's high-performance 850 platform with longitudinal mounting. This engine received no significant platform-specific adaptations during its short production run, as it was the top-tier engine for the limited-edition 850 T-5 R and 850 R models. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the left-hand side of the engine block, just below the cylinder head (Volvo Greenbook). The code will read 'B4164T3'. Critical differentiation from other B4xxx engines: The 'T3' suffix denotes the high-output 190 PS variant with specific ECU mapping and turbo configuration. Visually, the Garrett T25 turbocharger, red valve cover (on 850 R models), and performance-oriented intercooler piping are definitive identifiers.
The B4164T3's primary reliability risk is turbocharger wastegate actuator failure, with elevated incidence in engines subjected to aggressive driving. Volvo service documentation links this to heat cycling and mechanical wear, potentially leading to overboost and engine damage. Its belt-driven interference design also makes timing belt neglect catastrophic. Adherence to maintenance schedules is non-negotiable.
