Your snazzy new tires keep you on the road and your sharp brakes stop the vehicle in a fraction of a second, but you are traveling nowhere if your VW air-cooled engine has a problem. VWs from 1936 through the 2000s came with these types of engines. Air-cooled models work by allowing air to flow over and around the engine to cool it as you travel down the road, so it is fair to say that this engine is the most important part of your Volkswagen. The air-cooling method means your VW does not need a radiator or a way to regulate the engine's internal temperature. If you diagnose a fault with your VW Beetle air-cooled engine, it may be caused by the fins, which extend from the engine and pull away heat. Alternatively, a broken fan may stop cool air from traveling around the engine. Beetles could also have problems with the cylinders that assist the airflow, which lie horizontally near the fins. The classic flat-four engine is durable when compared to other motors; however, if it goes wrong, you can purchase VW air-cooled engine parts as well as full engines from the vast inventory on eBay.Shop the large inventory of motors, parts, accessories, and complete Volkswagen engines!
