The Vauxhall 28TD is a 2,771 cc, inline‑six turbo‑diesel engine produced between 1983 and 1993. It features an overhead camshaft (OHC) layout with indirect injection and a cast‑iron block with an aluminium alloy head. In standard form it delivered 63–70 kW (85–95 PS) and 190–210 Nm of torque, offering robust low‑end pulling power for executive and commercial applications.
Fitted to models such as the Senator Mk2, Carlton Mk2, and Bedford CF van, the 28TD was engineered fo…
Production years 1983–1993 predate formal Euro emissions standards; compliance limited to national regulations of the era .
The Vauxhall 28TD is a 2,771 cc inline‑six turbo‑diesel engine engineered for executive sedans and light commercial vehicles (1983–1993). It combines indirect injection with a KKK turbocharger to deliver strong low‑rpm torque and mechanical robustness. Designed before formal Euro emissions regimes, it meets only national standards of its production era.

The Vauxhall 28TD was used across Vauxhall's Senator and Carlton platforms with longitudinal mounting and also fitted to the Bedford CF van. This engine received platform-specific adaptations—revised engine mounts in the Carlton Mk2 and altered coolant routing in the Senator Mk2—and from 1988 the facelifted models adopted MLS head gaskets and updated torque sequences, creating minor 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 28TD is mechanically robust if maintained properly, but pre-1988 versions are susceptible to head gasket failure under load or overheating. Post-1988 models with MLS gaskets are significantly more durable. Regular coolant changes, correct torque procedures, and avoiding over-fueling help ensure longevity beyond 250,000 km.
Top issues include head gasket failure (pre-1988), turbo oil seal leaks, Bosch injection pump wear, and glow plug/relay faults. These are documented in Vauxhall service bulletins and workshop manuals from the mid-1980s to early 1990s.
The 28TD powered the Carlton Mk2 (1983–1993), Senator Mk2 (1983–1993), and Bedford CF van (1984–1990) in 2.8L turbo-diesel form. It was never licensed to other manufacturers. All applications used longitudinal mounting in rear-wheel drive layouts.
Modest gains are possible via injection pump recalibration (+10–15 kW), but the non-wastegated turbo and indirect injection limit potential. Over-fueling risks exhaust manifold cracking and head gasket failure. Most owners prioritize reliability over tuning due to the engine’s age and commercial heritage.
Typical consumption is 9.5–10.5 L/100km (27–30 mpg UK) in mixed driving. Highway cruising can achieve 8.2 L/100km (34 mpg UK), while city or load use may exceed 12 L/100km. Economy depends heavily on driving style and injection pump condition.
No. The 28TD is a non-interference OHC engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. This design enhances reliability in timing system failures.
Vauxhall specifies SAE 15W-40 mineral oil meeting API CD/CE standards. Modern synthetics are not recommended for original-spec Bosch pumps due to potential seal incompatibility. Change every 10,000 km or annually.
