History of the Volkswagen T25
First built in August 1979, the T25, also known in the USA as a Vanagon, and in Germany and the majority of Europe as a T3, was a huge success and a radical jump forward from the evolution between Splitscreen and Bay Window Campers and Transporters.
As you will be able to read below, by the end of production, the humble 1979, 1600cc CT model was replaced by a fuel injected 2100cc DJ unit and the practical, but not great, off road 2 wheel drive configuration was available as a four wheel drive (4x4) model known as a Syncro. The Syncro had a very respectable set of gearboxes and running gear produced in Austria by Puch. The syncro was available in 14 inch and 16 inch wheel sizes. As with the 2 wheel drive version, it could be ordered as a van, window van, microbus, Caravelle, Carat delux microbus, single cab pickup, double cab pickup and even in mid and high top versions, as well as a VW approved camping version made by Westfalia in Germany.
10 useful facts about the T25 (T3)
- The washer bottle is refilled by lifting the cab mat up, where you will find the washer bottle cap.
- To top up the brake fluid and on post 1981 versions, clutch fluid, you will need to remove the black cover to the instrument panels. But be careful, if you are a bit rough, the plastic tags holding the assembly to the dashboard break off!
- On a 2 wheel drive model, both petrol and diesel versions, the fuel tank is at the front (reassuringly straight under the drivers and passengers seats!) Because it has a concave top to the tank, mud and dirt can sit on the top of the tank and rust it out. Worth keeping an eye on.
- German produced vehicles post August 1985 were dip treated in the factory for rust prevention.
- If you have air in the water-cooled petrol or diesel models cooling system, it can cause them to overheat. To bleed out the system the front of the vehicle needs to be 30 to 45 cms higher than the rear (take care jacking up vehicles). The bleed valve is behind the grill.
- The Westfalia models with an elevating roof use the original hole that was designed for the metal ‘tilt and slide’ sunroof and is by far the strongest model of camper with an elevating roof.
- The last South African produced transporters came with a 5-cylinder petrol engine that in Europe was fitted to the Passat and Audi 80.
- The 1900cc and 2100cc water-cooled petrol engines are very ‘fussy’ about what antifreeze you use. If you use a run of the mill antifreeze, it can corrode the head studs in a very short number of months, causing all sorts of issues, including loss of power, water leaks into the bores etc. Always use the correct fluid like the J10916, which is made by FEBI in Germany to VW’s original specification.
- Porsche has created a version of the VW Transporter, but called it a B32, it was built as a limited edition. The van was equipped with 3.2 liter Carrera engine and was originally developed as a support vehicle for the Porsche 959, which took part in Paris-Dakar race.
- Lastly, a regular call to JK staff is “how do I check and fill up the oil on my T25?” There’s a flap behind the rear number plate. Pull the tag and all will be revealed…
Production history and technical updates
May 1979 Hanover built the first models of the ‘third’ generation Volkswagen Transporter. It was a total redesign of the old Bay Window, being wider with larger windows and tailgate, and a new front style. Very little was carried over from the previous model. There was new suspension, which moved away from the torsion bar system. Powered by either a 1600cc 50bhp (37kw) or 2000cc 70bhp (51kw) air-cooled engine.
February 1981 Introduction of a water-cooled 1600cc diesel engine with 50bhp (37kw). This engine originally came from the Golf.
September 1981 Introduction of the Caravelle, offering a more luxurious interior.
October 1981 Saw the first water-cooled flat four petrol engines in two versions: DF 1900cc 60bhp (44kw) and DG 1900cc 78bhp (57kw). Rear air intakes became plastic inserts.
1982 End of production of air-cooled engined models in Germany.
August 1983 Introduction of a higher spec ‘Caravelle’ with the option of a 4 lamp square grille.
1985 The year of a full ‘revamp’ of the model. Changes included new exhaust systems, front suspension, sliding door locks, fuel injection systems, to name but a few. It is said over 1000 changes were made in this year alone. 1985 also saw the introduction of the Syncro, a four wheel drive vehicle, which was built with Steyr/Daimler/Puch in Austria. Capable of climbing a 54% gradient utilizing a center viscous coupling.
1986 ...Onwards vehicles did not suffer so badly with rust as a result of a new rust treatment in the production process.
September 1990 The last T25 left the Hanover factory, however production carried on in South Africa until the end of 2002. The last Syncro was built in 1992.
Type 25 chassis numbers
The chassis number, also known as the VIN, can be found stamped inside the offside door pillar. Find the 10th digit of the VIN (Vehicle Identification Number) and, using the table below, this digit will give you the model year. Please note that the build dates run from August to July not January to December, so for example a 1981 model could have been built in late 1980.
The last 6 digits are the serial nos.

Type 25 paint codes
Please note, most of the versions sold as “Campers” started out as vans or microbuses and were converted by companies such as Viking, Devon and Bilbos. They very often painted the bottom half to give it a distinctive 2 tone look, but almost certainly not using original VW colours! JK supply a wide range of camper interior parts for conversion and restoration. Paint code information is correct to the best of our knowledge, however, we accept no responsibility for erroneous information.
