To tighten the timing chain on a Fiat Seicento SX, first ensure the engine is off and cool. Remove the timing chain cover, then inspect the tensioner and chain for wear. Adjust the tensioner according to the manufacturer's specifications, which may involve using a special tool or manually resetting it. Once adjusted, reassemble the cover and ensure everything is properly aligned before starting the engine.
