Old and New VW Parts: Air Cooled and Water Cooled
by : Phoenix Delray

Air cooled VW parts were needed for the early engines that were used in the models that were run off of the assembly line long ago. The later engines, including the ones that are made today, are cooled by water and are called water cooled engines. For people who are interested in restoring a VW vehicle, it is critical to make sure that you know what kind of engine is for the specific vehicle that you have.

Volkswagen aircooled parts of an engine rely on air circulating over them to cool them. Today, most engines are cooled by liquid coolant that runs through the engine, where the coolant absorbs heat. While water cooled engines have a radiator or heat exchanger, an air cooled engine does not. This is where the coolant releases heat into the air. Even though the engine is cooled by air in the end, this is not an example of air cooled Volkswagen parts at work. This would be water cooled VW parts working, because of the liquid coolant that is being used. Heat generated by the air cooled parts is released directly into the air. Some of the most frequently needed air cooled Volkswagen parts are the metal fins that cover the cylinders on the outside. These increase the surface area that the air can act on.

To get an idea of which Volkswagen models used air cooled VW parts and which ones did not, here is a very general list. The models that use the air cooled parts are the Bus, the Beetle, the Type 3, the Type 4, the Vanagon, and the Karmann Ghia. The newer models that use water cooled VW parts are the Cabriolet, the Quantum, the Cabrio, the Dasher, the Golf, Fox, Eurovan, the Jetta, the Passat, the new Beetle, and the Scirocco.

Even though the older models use air cooled VW parts, those engines are some of the most versatile internal combustion engines in the world. Volkswagen has made different versions of the engine starting with the VW Bus. The engine was first used in the 1930s. The classic Beetle may be one of the best known cars that used the air cooled VW parts. The first engine was a 36 horsepower engine, and the Type 2 Beetles and buses a few years later gave out 40 hp of power.

If you are in need of any air cooled or water cooled VW parts for your cherished Volkswagen, the most popular way to find whatever you need for your project is to look online at the various retailers and sellers that offer the VW parts on their websites.
