How to align the timing of Santana?

[Louise]

Santana timing method: Align the crankshaft according to the marks on the crankshaft timing pulley, generally requiring the No. 1 cylinder piston to be at the top dead center position. Install the camshaft timing pulley and align the marks on the camshaft. For dual camshafts, align the positions of both camshafts separately, then install the timing belt/chain. Below is an introduction to engine timing: 1. The engine valve timing mechanism controls the timing and duration of engine intake and exhaust. 2. Its function is to open and close the intake and exhaust valves of each cylinder in sequence according to the engine's working order, allowing fresh air to enter the cylinder and expelling the exhaust gases after combustion. 3. If the engine's valve timing is disrupted, the engine will not function properly.
