Specifically:
* Harmonic Balancer: You'll find a mark, often a small notch or a line, etched onto the outer edge of the harmonic balancer.
* Timing Cover: A corresponding mark will be on the timing cover, usually near the crankshaft. This mark might be cast into the cover or painted on.
Important Note: You'll need to align these two marks to set the timing correctly. The engine needs to be at top dead center (TDC) on the number one cylinder for this procedure to work. There will usually be a mark on the timing chain cover (or possibly the camshaft) to indicate the number one cylinder's TDC position. Consult a repair manual specific to your 1988 Ford Mustang LX 2.3L for precise location of these marks and the proper timing procedure. Incorrect timing can severely damage your engine.
