If the vehicle's engine has a timing system driven by a toothed belt, what specific maintenance must be carried out?

Question

DentroTest · Accepted Answer

The toothed timing belt is an element made of elastomer materials (reinforced rubber) that wears and ages both with mileage and with the passage of time. For this reason, the manufacturer's official maintenance plan requires its periodic preventive replacement to prevent it from breaking while running, which would cause catastrophic and irreparable damage to the valves and pistons. Greasing it is completely incorrect and harmful, since lubricants, greases and oils attack and quickly degrade the rubber material of the belt.
