If you have this car, you are most likely going to have to fix something, it's simply getting that old. Haynes manuals have always been my favorite, their explanations just make sense to me.
Each chapter gives the proper torque settings for related fasteners, fluid levels and types etc, right at the beginning, making it a perfect reference even if you already "know" what you're doing. Thanks to modern printing practices, the photos in the book are very clear.
This book covers everything you need to know. Be warned, if you haven't rebuilt an engine before, you are not going to learn it from the explanation in this kind of book.
Be warned that all measurements are metric, so make sure your torque wrench has Nm (Newton-Meters).
