The GRM belt is one of Chery Bonus's weaknesses. Some of the main problems of the belt are:
- a reduced resource-at the declared resource of 40,000 km, the belt has to change more often, sometimes every 10 to 15,000 km;
- Low quality-belts of EMG are rapidly relaxed, stretched and cracking, with the result that the resource is reduced;
- The damage to the GRM Chery Bonus can without any prerequisites to pull out several teeth, resulting in damage to the valves and the pistons.
Therefore, it is necessary to monitor the GRM-belts and the first signs of wear are better replaced. At the same time, a new tension clip is installed with the replacement of the belt.
