How to install the generator belt of Changan CS75?
2 Answers
Loosen the generator fixing screw and the belt tension adjustment screw, push the generator towards the engine to minimize the distance between the pulleys, then put the belt on and align it, adjust the belt tension to the appropriate level, and finally tighten the engine fixing screw and the adjustment screw. The following are precautions for generator use: 1. Regularly clean the accumulated dirt and dust on the generator surface to maintain cleanliness and good ventilation. 2. Frequently check the tightness of all fasteners related to the generator and tighten all screws in time. 3. The tension of the drive belt should be appropriate. If it is too loose, it is prone to slipping and causing insufficient power generation; if it is too tight, it is easy to damage the belt and generator bearings. 4. When installing the battery, never install it incorrectly. Usually, the positive line is installed first, and the ground line is not installed, otherwise the diode is extremely easy to burn out.
The first time I tried replacing the alternator belt myself, I was really nervous. The engine compartment layout of the Changan CS75 is a bit complicated, and I was too lazy to check the manual at first, which made me spend a long time just finding the tensioner pulley. You'll need to prepare a wrench and a new belt—make sure the model is correct, and I recommend using genuine parts to avoid mismatches. The engine must be cool during installation to prevent burns, and the battery negative terminal should be disconnected first to prevent short circuits. Once you locate the tensioner pulley, use the wrench to turn it counterclockwise to release tension—the old belt should come off with a gentle pull. Route the new belt according to the diagram printed under the hood, aligning each pulley carefully to avoid slipping off the groove. After installation, adjust the tension—not too tight or too loose—pressing the middle of the belt should allow a slight give. Finally, tighten the tensioner pulley bolt, start the car, and test for a few minutes to ensure there are no unusual noises. This job tests your patience, but doing it yourself saves a lot of money—tools cost just a few dozen bucks. If you're unsure, better call a mechanic than risk messing it up.
