Made in ever more resistant materials, like nylon, neoprene and fibreglass, this type of belt is toothed on the inner part. Each tooth is shaped to perfectly match the camshaft pulley and the crankshaft.
Toothed belts have several advantages: they do not require lubrication and are notably quiet as there is no contact between metal parts.
Remember that they must never be folded, twisted or forced because they contain fibreglass that could be damaged if subject to stress. Having it checked regularly is fundamental to preventing its accidental breakage, causing damage to the engine.
