Good advice on car care, maintenance, and upgrades for your Porsche is available on both the regional and national levels. The PCA maintains an extensive archive of technical questions and answers for all models of Porsches. Chances are, if you have a question, it has already been dealt with on the PCA site (see Technical on the top menu). If it hasn’t been, you can submit a new question for a prompt and expert answer. Tech Tactics articles that were published in the Shenandoah Region newsletter The Heat Exchanger are available from below.
