How to align the timing marks for Santana 1.8?

[ElisaFitz]

Align the crankshaft according to the marks on the crankshaft timing belt pulley, generally requiring the No. 1 cylinder piston to be at the top dead center position. Below is relevant information about the timing belt: 1. Definition explanation: The timing belt is an important component of the engine's valve system. It ensures accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific transmission ratio. 2. Purpose: The timing belt serves as a link between the upper and lower parts. The upper part connects to the timing pulley on the engine cylinder head, while the lower part connects to the crankshaft timing pulley. The timing pulley is connected to the camshaft, which has cams. The contact points of these cams are the small rocker arms. The rocker arms generate pressure through the power transmitted by the timing belt, achieving a lifting effect.
