Greatwall v200 4cyl 2.0ltr turbo ...

MY 2015 Greatwall V200 diesel Snapped a Timing belt (Factory belt). .Vehicle has done alot of work since I brought itat 145000 km ... Timing belt snapped 176000 km... ..(Factory maekings on belt... Timing belt replacement is between 60,000km and 75,000km .. Factory timing bely has lasted 3x longer then reconmended... (SUPER BELT??)
♤QUESTION IS ... HAVE I DAMAGED ENGINE ?? DO PISTONS HIT VELVES?? Can i slap a Timing belt on and use as normal?? WITHOUT HEAD REPLACEMENT??
