Roewe 550 timing belt alignment method is: Use a wheel block to secure the timing wheel of the engine to prevent the wheel from turning during chain tooth alignment; Locate the blue timing chain tooth on the engine camshaft; Align the colored chain on the engine with the small dot on the camshaft; After marking, use a wrench to clamp the timing shaft so that the marked chain tooth can be secured; Release the clip holding the engine timing wheel, and the timing alignment is complete. Taking the 2014 manual Zhi Xuan edition Roewe 550 as an example, its body dimensions are: length 4648mm, width 1827mm, height 1483mm, with a wheelbase of 2750mm.
When repairing the timing belt on my Roewe 550, I found alignment to be the most critical step. First, ensure the engine is cold and disconnect the battery for safety. Locate the timing marks on the crankshaft and camshaft, usually indicated by an arrow or TDC mark on the front engine cover. Use a special wrench to secure the crankshaft pulley to prevent rotation. Then install the new belt, starting by fitting it onto the crankshaft pulley, carefully aligning the camshaft marks—a flashlight can help inspect details. After alignment, adjust belt tension using the tensioner pulley, ensuring no slack. Double-check repeatedly during the process, as even a slight misalignment could cause engine damage, leading to repair costs of thousands. I recommend using a digital feeler gauge for precision. The Roewe 550's timing belt lifespan is about 60,000 km; regular replacement avoids such trouble. It's best to prepare a complete tool kit, but for non-professionals, I'd suggest getting it done at a 4S shop—saving both money and hassle.
When it comes to the timing belt on the Roewe 550, you need to be extra careful. The key is to prevent internal engine components from colliding. You must locate the synchronization point, which is the zero mark on both the crankshaft and camshaft, and take a photo for reference. During alignment, turn the crankshaft bit by bit while monitoring the camshaft position, securing it with a standard wrench. After installing the new belt, check the tension and adjust it using the tensioner to ensure it's tight but not overly so. The entire process is best done on level ground, and don't rush to start the engine. I remember the last time I misaligned it, it resulted in strange noises, costing nearly 2,000 RMB to fix the engine. If you're doing it yourself, the risk is quite high, especially for beginners who are prone to mistakes—it might be better to spend a few hundred at a professional shop. Regular maintenance should include cleaning the marking points to reduce misjudgment, with safe driving as the top priority.
For aligning the timing belt on a Roewe 550, I'll share a simple method: Locate the standard marks on the engine crankshaft and camshaft, which usually have notches or labels. Once aligned, the belt will be in position. When installing a new belt, start by fitting it over the crankshaft pulley first, then loop it around the camshaft, ensuring a smooth and snug fit. Adjust the tensioner to medium tightness and test by hand to prevent looseness. Double-check the marks before finishing to avoid mishaps. If the engine starts without unusual noises, you've succeeded. This job requires careful attention, as a snapped belt can damage the engine. Be meticulous if doing it yourself, and ask a friend to assist if needed.
