tbelt warning light refers to the timing belt alarm light, and the timing belt should be replaced as soon as possible. The functions of the belt are: Ensure the accuracy of intake and exhaust timing; Ensure the synchronization of engine ignition and cylinder movement; Ensure the smooth power output of the engine. The method to replace the car belt is: Lift the vehicle and remove the right front wheel inner fender liner; Remove the generator belt and the generator belt tensioner; Loosen the crankshaft pulley screw; Open the engine hood and remove the water tank; Remove the engine mounting bracket and the protective cover on the belt; Unscrew the generator fixing screw and remove the generator; Remove the cylinder block mounting bracket and take off the crankshaft pulley; Rotate the crankshaft to the top dead center position of the cylinder and mark it; Remove the belt and the tensioner.
I've been driving trucks for twenty years, and this thing is the timing belt warning light. It once lit up on the highway, scaring me into pulling over immediately. The timing belt is like the heart's metronome of the engine—if it snaps, the valves and pistons can collide and turn into scrap metal. Common issues include belt wear, tensioner failure, or skipped teeth, and it usually needs replacement every 80,000 kilometers. Once, a teammate tried to save money by not replacing it, and the engine overhaul ended up costing five figures. If you see this light come on, don't push your luck—find a safe spot to pull over, turn off the engine, and call a tow truck to take it to the repair shop. Replacing the belt, including parts and labor, only costs a few hundred bucks. Don't penny-pinch and risk a major loss.
Previously, my used car had this warning light on, and I found out from the manual that it indicated a timing belt issue. This component controls the opening and closing timing of the engine valves, and being made of rubber, it can crack or even break over time. The most troublesome part is that it can fail without any warning. Last time, my neighbor's car had the belt snap, which directly bent the valve rods. I learned to inspect it myself by unscrewing the oil cap and using a flashlight, only to find the belt edges were frayed. I recommend replacing it every 60,000 to 80,000 kilometers as per the maintenance manual, and for some cars, the water pump should be replaced at the same time. Remember, if the light comes on, don't continue driving—the engine could seize at any moment.
