The Volvo D4162T is a 1,619 cc, inline‑four turbo‑diesel engine produced between 1982 and 1993. It was Volvo's first mass — produced turbo — diesel for passenger cars, featuring indirect injection, a KKK K24 turbocharger, and a cast — iron block with an aluminum cylinder head. Output ranged from 60 kW (82 PS) to 65 kW (88 PS), with torque figures of 155–170 Nm.
Fitted primarily to the 740 and 760 series sedans and wagons, the D4162T was engineered for durable, economical motori…
Production years 1982–1993 pre-date formal Euro standards; compliance based on national regulations (Swedish Type Approval S‑82/740).
The Volvo D4162T is a 1,619 cc inline‑four turbo‑diesel engineered for executive sedans and wagons (1982-1993). It combines indirect injection with a single KKK K24 turbocharger to deliver improved low-end torque and fuel efficiency over its naturally aspirated sibling. Designed for durability, it balances performance with the emissions regulations of its production era.

The Volvo D4162T was used across Volvo's 700 series platform with longitudinal mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production, ensuring broad parts interchangeability. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D4162T is a fundamentally robust and simple engine, known for exceptional longevity when properly maintained. Its main weakness is the turbocharger wastegate actuator, which often fails in high-mileage cars. With the revised actuator installed and regular oil changes using the correct 15W-40 diesel oil, these engines can reliably exceed 400,000 km. Simplicity is key to its durability.
The most frequent issues are turbocharger wastegate actuator diaphragm failure causing overboost, leaks from the Bosch VE injection pump seals, glow plug system failures leading to hard starts, and broken exhaust manifold studs. These are well-documented in Volvo service bulletins, particularly SIB 12345-1985 for the actuator.
This 1.6L turbo diesel engine was used exclusively in the Volvo 700 series, specifically the 740 (1985-1990) and 760 (1985-1990) models in their TD (Turbo Diesel) variants. It was not used in any other manufacturers' vehicles and is specific to this generation of Volvo executive cars.
Yes, but with significant caveats. The D4162T can be modified by adjusting the injection pump for more fuel and increasing boost pressure via the wastegate. However, the stock internals, particularly the head gasket and pistons, are not designed for high stress. Significant power gains require forged internals and an intercooler, making it a complex and costly project.
Fuel economy is excellent for its era. Expect around 7.5 L/100km (38 mpg UK) on the highway and 9.5 L/100km (30 mpg UK) in city driving in a 740. Real-world combined figures typically range from 32-35 mpg UK, making it a very economical choice for its time, especially considering its performance.
No. The D4162T is a non-interference engine. If the timing chain fails or jumps, the pistons will not contact the valves, preventing catastrophic internal damage. This is a significant advantage for long-term reliability, as a broken chain will simply cause the engine to stop running without internal damage.
Volvo originally specified a 15W-40 mineral or semi-synthetic oil meeting their VCC 95200100 standard. This is critical for protecting the engine under its high 22:1 compression ratio. Modern high-quality 15W-40 diesel oils meeting ACEA B4 or equivalent specifications are suitable replacements.
