To effectively diagnose a vacuum leak in your 1997 Chevrolet Astro, begin with a thorough visual inspection of the vacuum lines and connections. Look for any signs of wear, cracks, or disconnections that could indicate a problem. While the engine is running, listen carefully for any hissing sounds, as these can be telltale signs of a vacuum leak. Utilizing basic tools such as a smoke machine or carburetor cleaner can significantly aid in your diagnosis. Familiarize yourself with the vacuum diagram specific to your vehicle, as this will guide you in identifying potential leak points. A practical method to confirm leaks is the spray test; while the engine is running, spray carburetor cleaner or a similar substance on the vacuum lines and gasket joints.
