I have heard that there are two different types of timing belts that are found on vehicles today. Is this so?
Yes, Originally belts were constructed of neoprene, which is still used, but due to increased engine demands , a new “tougher” belt has been constructed. It is made of HSN(highly saturated nitrile material that has high tensile strength cord construction to minimize stretch and tough wear resistant fabric on the working tooth surface, designed to handle wide speed variations and constant driveline power requirements.
