How to align the timing of the Roewe 350?

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.

As a DIY car enthusiast, I've worked on the timing of my Roewe 350 several times. Simply put, it's all about aligning the marks step by step. First, prepare a socket wrench and the manual, then turn off the power and remove the timing cover. Locate the small mark on the crankshaft and rotate it to a specific angle, then align the marks on the camshaft gears as well. If it's a chain, make sure the chain links are properly seated. During the actual operation, you might encounter a loose chain or faint marks—taking photos can be a big help. I used to take pictures with my phone to double-check if I made any mistakes. The key is not to rush; if you do, the marks might misalign, and incorrect timing can prevent the engine from starting or cause a significant increase in fuel consumption. So, always test the engine after finishing the job. By the way, regular replacement of the chain or belt can extend its lifespan. If the Roewe 350 uses a chain, it's relatively more durable.

As a new car owner who just learned how to adjust the timing, I found the Roewe 350 isn't too difficult but requires caution. The basic method is to open the hood, refer to the user manual to locate the timing marks on the camshaft and crankshaft, then align them properly. During operation, use a wrench to slowly rotate to the dead center point, ensuring the marks perfectly coincide without misalignment. If you're worried about mistakes on your first attempt, you can watch demonstration videos online first – YouTube has free tutorials that explain the steps in detail. Don't neglect safety: disconnect the battery and wear gloves to prevent cuts. If alignment fails, don't force it – misalignment can damage the engine and lead to expensive repairs. I recommend practicing multiple times during the learning phase or asking a friend to supervise until you're comfortable doing it independently. Also remember to regularly check the chain for signs of wear.

As a safety-conscious driver, I always consider the risks first when dealing with the timing of my Roewe 350. Misaligned timing can range from the engine failing to start to severe damage like pistons hitting valves, potentially ruining the engine. The alignment method involves following the manual's guidance to align the timing marks on the crankshaft and camshaft, possibly requiring specialized tools like locking pins to secure positions. The steps are straightforward but require precision in details: for instance, stopping the crankshaft at a specific angle and ensuring the cam gear marks match perfectly. Always disconnect the battery before actual operation to prevent accidental starts; if you're not experienced, it's best to take it directly to a professional shop to avoid DIY mistakes that could lead to accidents. I once experienced incomplete mark alignment, resulting in constant strange noises while driving. After repairs, I learned my lesson and now have a technician regularly check the chain and wear levels every few tens of thousands of kilometers to prevent issues. Safety first is far more important than saving money.
