The installation tutorial for replacing the timing belt on the Changan CS75 is as follows: 1. Keep the first cylinder piston at the top dead center position, and align the notch on the outer edge of the crankshaft timing belt pulley with the raised mark on the pulley chamber. 2. Ensure that the pulley chamber and all transmission belt pulleys are clean, free of oil and water. If necessary, clean them with a clean white cloth. 3. After fixing the fuel injection pump timing belt pulley with a special tool, tighten the nut according to the specified torque. Use an M8 tool positioning bolt to position the camshaft timing belt pulley and the fuel injection pump timing belt pulley at the corresponding threaded hole positions of the pulley chamber. Assemble the tensioner assembly on the pulley chamber and fix it with a hexagonal flange positioning bolt. Taking the Changan CS75 2021 Glory Million Edition 280T Manual Elite as an example: its length, width, and height are 4650mm, 1850mm, and 1715mm respectively, with a wheelbase of 2700mm. It is equipped with a 6-speed manual transmission, and the body structure is a 5-door, 5-seat SUV.
Last time I replaced the timing belt on my CS75, I made some preparations. The tools had to be complete: socket wrench, torque wrench, and jack stands. First, disconnect the negative battery terminal for safety, then remove the radiator fan and water pump to make space. Once the timing cover is off, release the tensioner to remove the old belt. The key step is aligning the camshaft and crankshaft marks before installing the new belt—don’t be careless here, or the engine could be ruined upon startup. Adjust the tension using a tool, not manually, to avoid overtightening. After reassembly, test the engine for smooth operation. The whole process took me two hours. The CS75’s engine bay is compact, so patience is required. Generally, it’s recommended to replace it every 60,000 kilometers to save on repair costs, but I studied the manual beforehand.
For those of us who frequently repair cars, when replacing the CS75 timing belt, safety procedures are prioritized: disconnect the power, remove the auxiliary belt and front cover assembly. Use professional tools to ensure precise alignment of the crankshaft and cam gear marks during timing alignment—this step is critical, as any mistake here can lead to complete failure. Before installing the new belt, check the wheels for wear; set the tension to the standard value without exceeding the limit. During the test start, don’t rush—slowly turn it twice to check for any abnormal noises. It’s recommended to refer to the manual or seek professional service, as belt quality significantly affects lifespan. Taking the time to inspect other components, such as the water pump, is also worthwhile.
