The Volvo D24T is a 2,383 cc, inline‑six turbocharged diesel engine produced between 1982 and 1993. It features a single overhead camshaft (SOHC), indirect injection via pre — chambers, and a mechanically controlled K27 turbocharger, delivering outputs of 85–90 kW (116–122 PS) and 230–240 Nm of torque. Its robust cast — iron construction was engineered for durability and longevity in demanding conditions.
Fitted primarily to the 240, 740, and 760 series sedans and wago…
Production years 1982–1993 meet pre-Euro and Euro 1 standards depending on model year and market .
The Volvo D24T is a 2,383 cc inline‑six turbocharged diesel engine engineered for rear-wheel-drive sedans and wagons (1982-1993). It combines indirect injection with a single K27 turbocharger to deliver strong low-end pulling power and renowned mechanical durability. Designed to meet pre-Euro and Euro 1 emissions standards, it prioritizes reliability and serviceability over high output.

The Volvo D24T was used across Volvo's rear-wheel-drive platform with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 760 for luxury sedan duty-and no significant facelift revisions affecting core compatibility occurred during its production. 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.
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.
Analysis derived from Volvo technical bulletins (1985-1993) and aggregated owner club maintenance data (2000-2023). 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 D24T is renowned for exceptional long-term reliability and durability, often exceeding 300,000 km with basic maintenance. Its main weakness is the turbocharger oil seals, which are prone to failure in high-mileage engines. Addressing this and maintaining the glow plug system ensures decades of dependable service.
The most frequent issues are turbocharger oil seal leaks causing blue smoke, glow plug or relay failures leading to hard cold starts, and injection pump timing drift causing poor running. Coolant leaks from the plastic thermostat housing are also very common. These are well-documented in Volvo service literature.
The D24T was used in the Volvo 240 Series (1982-1993), 740 Series (1985-1990), and 760 Series (1985-1990), specifically in the 'Turbo Diesel' trim level for all models. It was not used in any other Volvo vehicles or licensed to other manufacturers.
Yes, but gains are modest. The primary method is adjusting the Bosch VE pump's maximum fuel screw and boost compensator, potentially yielding +10-15 kW. Upgrading the turbo to a K27 hybrid or K28 can help, but the engine's indirect injection and high compression limit significant power increases without risking head gasket failure.
Fuel economy is excellent for its size and era. Expect around 8.5 L/100km (33 mpg UK) in combined driving for a 240, and slightly more for heavier 740/760 models. Real-world figures typically range from 30-35 mpg UK, making it a very economical choice for its time.
No. The D24T 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 major advantage for long-term ownership and maintenance peace of mind.
Volvo specifies a 15W-40 diesel-rated oil meeting their VCC 95200312 standard. Using a quality diesel oil with adequate detergents is crucial for protecting the turbocharger and keeping injectors clean. Change intervals should not exceed 10,000 km or 12 months.
