How to align the timing belt marks on Peugeot 408?

Peugeot 408 alignment method for timing belt marks: 1. Remove the timing belt; 2. Align the marks on the two large gears at the outer end of the camshaft; 3. There is a mark at the 12 o'clock position, after alignment, locate the scale on the plastic cover at the crankshaft end; 4. Rotate the crankshaft to align it with the zero mark; 5. After the timing is aligned, install the belt. The Peugeot 408 is a compact car under Dongfeng Peugeot. Taking the Peugeot 408 2020 230THP 10th Anniversary Edition as an example, its body dimensions are: length 4750 mm, width 1820 mm, height 1488 mm, wheelbase 2730 mm, and fuel tank capacity 53 liters.

I've been driving a Peugeot 408 for several years and have replaced the timing belt myself multiple times. Aligning the marks is absolutely crucial. First, you need to locate the correct positions: there's usually a small indentation or notch on the engine crankshaft pulley, and similar markings on the camshaft gear. When aligning, start by turning the engine to top dead center (TDC) to ensure all components are synchronized. Then, install the new belt step by step, making sure the tensioner is adjusted just right—too loose and it'll slip, too tight and it may snap. I recommend using a locking tool to secure the camshaft to prevent shifting. After aligning the marks, manually rotate the engine two full turns to verify the markings still align. If there's any deviation, you'll need to start over. Last time I forgot to check before starting, the engine shook violently—luckily I stopped it in time before major damage occurred. Don't cut corners; taking the time to do it meticulously can save you from costly overhauls.

In the maintenance of timing belts, alignment marks are crucial, especially for models like the Peugeot 408. The marks on the crankshaft and camshaft must be precisely aligned. The general method is to slowly rotate the engine to the top dead center position using a wrench, then locate the reference symbols on the wheels—usually a small dot or line. When installing the belt, ensure all teeth are aligned carefully to avoid being off by half a tooth. After tensioning, don't forget to double-check to confirm there's no displacement before starting. If not aligned properly, the engine timing will be disrupted, leading to valve collision with pistons, which can cause major trouble and cost thousands to repair. Regular maintenance should include checking the belt's wear and tear; replace it promptly when worn out to maintain engine longevity.

This is my first time learning this, and seeing others align the timing belt marks on the Peugeot 408 looks quite intimidating. Simply put, just look for the marks on the engine: there's a dot on the crankshaft and a line on the camshaft—align them and you're good. But when actually doing it, be careful. The engine must be completely stopped, and the belt should be installed slowly from the side, ensuring each tooth is perfectly seated. After alignment, rotate the engine to test for any unusual sounds. If you're unsure, it's best not to mess with it and seek help from a professional shop, as damaging the engine would be a huge loss. Remember to check the belt regularly to prevent it from breaking and leaving you stranded on the road.

Misalignment of timing belt marks poses significant risks. For example, incorrect installation on a Peugeot 408 may cause internal engine component damage or even complete engine failure. During alignment, ensure the reference marks on both the crankshaft and camshaft—typically notches or dots—are perfectly matched during installation. The procedure involves: first rotating the engine to a specific position (top dead center), then securing components, installing the belt, and adjusting tension. Before completion, manually rotate the engine to verify alignment—if marks deviate, the installation is incorrect. Never rush the process; complete each step meticulously with safety as the top priority. Additionally, considering belt material aging, replacement every 60,000 kilometers is recommended.
