How to align the timing of the Roewe 350?
2 Answers
The method to align the timing of the Roewe 350: Open the engine cover, there are two round holes on the camshaft that should be vertically upward. On the left side of the three-way catalytic converter, near the transmission position, there is a small hole about the size of a chopstick. Insert a sturdy iron rod into it. Turn the engine until the iron rod inserts into the small hole on the flywheel, then lock the camshaft with the two round holes vertically upward. The Roewe 350 is a compact sedan positioned in the A-segment market, launched by SAIC Motor following the Roewe 750 and Roewe 550. In terms of body dimensions, the Roewe 350 measures 4521mm in length, 1788mm in width, and 1492mm in height.
I've been in automotive repair for many years and am quite familiar with the timing alignment of the Roewe 350. The first step is definitely to disconnect the negative terminal of the battery for safety, then remove the timing cover to locate the timing marks on the camshaft and crankshaft. The Roewe 350 typically uses a chain, so you need to manually rotate the crankshaft to the dead center position to align the marks; the cam lobes on the camshaft should face upward or at a specific angle, which should be referenced from the manual. Don’t overlook the details—special tools like a crankshaft pin can be a big help. If the marks slip or aren’t aligned properly, the engine will shake violently when starting, and in severe cases, it can cause the chain to skip teeth or even damage the engine. Whenever I do this job, I always remind myself and my apprentices: take your time to ensure precision. After aligning the marks, manually rotate the engine a few times to confirm everything is correct before reassembly. I recommend checking the tension of the timing chain every 50,000 kilometers to prevent issues.
