SG Tool Aid 33650 Top Dead Center Indicator Whistle Tool

The SG Tool Aid 33650 Top Dead Center Indicator is a precision diagnostic tool that uses an audible whistle to accurately identify when a piston reaches Top Dead Center (TDC) on the compression stroke. This innovative tool whistles as the piston approaches TDC and stops when the piston reaches the exact top position, eliminating guesswork in timing-related diagnostics and adjustments.

Key Features:

• Audible whistle system provides precise TDC identification on compression stroke
• Eliminates guesswork when diagnosing jumped timing belts and timing chains
• Essential for valve adjustments and installation of distributors, timing belts, and timing chains
• Universal 2-in-1 fitting threads into both 14mm and 18mm spark plug ports
• Extended 27-inch overall length provides easy access in tight engine compartments
• Includes detailed instructions for proper use

Important Note: Not for use on diesel engines. This tool is designed specifically for gasoline engines with spark plug access.
