The Volkswagen RE is a 1,584 cc, air‑cooled flat‑four petrol engine produced between 1973 and 1983. It featured an overhead‑valve (OHV) layout with a single downdraft carburettor and delivered 50–60 PS depending on market and application. Its air‑cooled design eliminated the need for a radiator, enhancing reliability in remote or cold climates.

Production years 1973–1983 predate EU emissions regulations; compliance is limited to national standards in force at time of manufacture .
The Volkswagen RE is a 1,584 cc air‑cooled flat‑four petrol engine engineered for light commercial and passenger vans (1973–1983). It combines a single carburettor induction system with OHV valvetrain to deliver low‑rpm torque and mechanical simplicity. Designed before Euro emissions standards, it prioritizes serviceability and durability over environmental controls.

The Volkswagen RE was used across Volkswagen's Type 2 (T2) platform with rear‑mounted longitudinal layout and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Panel Van and revised cooling shrouds in the Westfalia camper—and from 1976 the 1600E model introduced updated valve seals and carburettor jetting, 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 RE is mechanically simple and robust when properly cooled and maintained. Early models (1973–1975) are more prone to oil consumption due to cylinder wear. Later revisions improved valve seals. Regular oil changes with 20W-50 mineral oil and cooling system checks are essential for longevity beyond 100,000 km.
Top issues include cylinder bore wear causing oil consumption, carburettor idle faults, oil leaks from pushrod tubes, and overheating from damaged cooling shrouds. These are well-documented in Volkswagen TSB T2‑74‑12 and workshop manuals.
The RE powered the Type 2 (T2) Bus, Panel Van, and Westfalia Camper from 1973 to 1983, primarily as the 1600S and 1600E variants. It was not used in Beetles or other platforms. All applications are rear-engine, air-cooled configurations.
Modest gains are possible via dual-carburettor manifolds, performance camshafts, or cylinder head porting—typically +10–15 PS. However, the low 7.5:1 compression ratio and air-cooling limit safe tuning. Significant power increases risk overheating and accelerated wear without major cooling upgrades.
Typical consumption is 10–12 L/100km (24–28 mpg UK) in mixed driving for a T2 Bus. Highway cruising may achieve 9 L/100km (31 mpg UK), while city or hilly routes can exceed 13 L/100km (22 mpg UK). Carburettor condition and tyre pressure significantly affect real-world figures.
No. The RE is a non-interference engine. If the timing gears fail (rare), the pistons will not contact the valves, preventing catastrophic internal damage. This design enhances safety during timing component wear.
Volkswagen specifies SAE 20W-50 mineral oil meeting API SF/CC. Synthetic oils are not recommended due to potential oil pressure fluctuations in the wide-clearance bearings of this vintage air-cooled engine. Change every 5,000 km or 6 months.
