take careful note of is the year

Well, the first thing to take careful note of is the year. VW parts manuals change accordingly with each and every edition that comes out. After all, information is not stagnant. It does not stay as it is. New discoveries in different fields push the boundaries of acceptable knowledge every day. So it follows that even car parts manuals, links london too, will accommodate such changes in their technical specifications and procedural details. For instance, early car models utilized exhaust manifold heat control valves that were operated mechanically by way of a thermostat spring and a corresponding counterweight. It wasn't until the year 1975 when car models appeared with vacuum operated heat valve controls.
