The timing belt of Volkswagen Jetta should be replaced every 80,000 kilometers. The following are the steps for replacing the timing belt: 1. Remove the valve cover, detach the crankshaft pulley, and take off the timing chain cover; rotate the crankshaft to bring the first cylinder to top dead center, then tighten the crankshaft fixing screw to secure the crankshaft; 2. Rotate the intake and exhaust camshafts. There are grooves at the rear of the camshafts; align the grooves of both camshafts evenly and insert the special tool; 3. Remove the old chain and install the new one. The crankshaft pulley does not have a keyway. During installation, align the round hole on the pulley with the groove on the timing chain cover.
Speaking of the timing belt replacement for Jetta, as an owner who has driven an old Jetta for over a decade, I have personal experience. When my car reached 80,000 kilometers, the belt showed obvious signs of aging. After taking it to the repair shop for inspection, the mechanic strongly recommended replacing it. He said the design lifespan of the Jetta's belt is around 80,000 kilometers, and if not replaced, there's a risk of breakage. Once it breaks, the engine could suffer severe damage, potentially costing tens of thousands to repair. I spent a few hundred dollars to replace the belt at that time, and the car ran smoother afterward, saving me future troubles. I suggest everyone not to be lazy—regularly check the belt's condition, feel for any cracks or hardening, and don't wait until the mileage exceeds the limit to panic.
