How do you align the timing belt on a Suzuki Alto?

To align the timing belt on a Suzuki Alto, first ensure the engine is at top dead center (TDC) for cylinder one. Align the timing marks on the crankshaft and camshaft pulleys according to the service manual. Once the marks are correctly positioned, place the timing belt over the pulleys, ensuring it is taut and that the tensioner is properly set. Finally, rotate the engine by hand to confirm that everything moves freely without interference.
