Where are the camshaft marks for a Fiat polio?

The camshaft marks on a Fiat Punto (commonly referred to as "Polio" in some regions) are typically found on the camshaft sprockets. They align with corresponding marks on the engine's timing cover or the cylinder head when the engine is at the top dead center (TDC) of the first cylinder. It's crucial to ensure these marks are correctly aligned during timing belt installation to maintain proper engine timing. Always refer to the specific service manual for your model year for precise locations and procedures.
