The Cadillac DL 52 is a 1,490 cc, inline — three turbocharged diesel engine produced between 2022 and 2026. It features dual overhead camshafts (DOHC), 12 — valve configuration, and Daihatsu's common — rail direct injection system with variable geometry turbocharging. In standard tune, it delivered 70 kW (95 PS) at 4,000 rpm and 220 Nm of torque at 1,500–2,800 rpm, offering strong low — end performance and refinement for compact applications.

The Cadillac DL 52 was used across Cadillac's XT4/XTS platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-increased cooling capacity in the XT4 and revised intake manifolds in the XTS-and from 2024 the updated fuel pump with improved internal coatings, creating interchange limits. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DL 52 is mechanically robust with good longevity when properly maintained. Early models (2022-2024) are prone to high-pressure fuel pump wear, but post-2024 revisions resolved this with improved internal coatings. Regular oil changes (every 15,000 km), use of correct Daihatsu 5W-30 oil, and attention to fuel system ensure long-term reliability. The strong inline-three architecture supports high mileage with minimal wear when serviced correctly.
Primary issues include high-pressure fuel pump wear (especially pre-2024), EGR valve clogging, turbocharger actuator sticking, and coolant leaks from the water pump. These are well-documented in Daihatsu service bulletins and stem from component aging, thermal stress, and maintenance neglect. The 2024 pump update significantly improved system durability.
The DL 52 was used in the XT4 and XTS for European and select international markets. It was part of Cadillac's strategy to offer compact diesel powertrains in regions with demand for fuel-efficient luxury SUVs and sedans. No licensed applications outside Cadillac. The engine was developed by Daihatsu and shared with other Toyota Group models.
Yes. The DL 52 responds well to ECU remapping, with safe gains of +15-25 PS achievable on stock hardware. Aftermarket upgrades like performance intercoolers, exhausts, and EGR deletes allow even greater increases. The robust inline-three bottom end supports moderate tuning without internal modifications. Enthusiasts often pair ECU tuning with intake and exhaust modifications for improved throttle response.
In combined driving, expect 4.8–5.5 L/100km (59–51 mpg UK). Highway cruising can achieve ~4.5 L/100km (~63 mpg UK), while city driving may exceed 6.5 L/100km (43 mpg UK). Real-world figures depend on driving style and vehicle weight, with XT4 models generally more efficient than XTS. The engine's torque curve contributes to responsive urban performance.
Yes. The DL 52 is an interference engine. If the timing chain fails or skips, pistons will contact open valves, causing catastrophic internal damage. While the double-row roller chain is durable, any signs of rattle or tensioner wear should be investigated immediately to prevent engine seizure. Regular oil changes help maintain chain tensioner function and lubrication.
Daihatsu specifies SAE 5W-30 oil meeting API CK-4 standard. Use a high-quality synthetic designed for turbocharged diesel engines. Change oil every 15,000 km or annually to protect the fuel pump, timing chain, and EGR system. Proper lubrication is essential for long-term reliability, especially under sustained load or high-temperature operation.
