The 3SZ engine is a 1.5L inline 4-cylinder DOHC engine used in the Daihatsu Terios and Toyota Avanza. Here are the general steps for setting the timing on a 3SZ engine:
1. Remove the timing cover to access the timing belt and timing marks.
2. Rotate the engine by hand until the timing marks on the camshaft and crankshaft gears are aligned. The specific timing marks and their positions will vary by engine model.
3. Check the position of the number one cylinder's piston. It should be at top dead center (TDC) on the compression stroke. You can use a piston stop tool to hold the piston in place.
4. Loosen the timing belt tensioner and remove the old timing belt.
5. Install a new timing belt, making sure that the timing marks on the camshaft and crankshaft gears are still properly aligned.
6. Tighten the timing belt tensioner to the manufacturer's specified torque settings.
7. Rotate the engine by hand to ensure that the timing belt is properly tensioned and that the timing marks are still aligned.
8. Replace the timing cover.
9. Start the engine and check the timing with a timing light. The timing should be set to the manufacturer's specifications.
It is important to consult a service manual or a qualified mechanic for specific instructions and torque specifications for your particular vehicle. Any mistakes during the timing setting process can cause serious damage to the engine and other components.
