What is the installation method for the timing belt of the Chery Tiggo 3?

[Harrison]

Installation method for the timing belt of the Chery Tiggo 3: 1. Remove the valve cover, detach the crankshaft pulley, and take off the timing chain cover. Rotate the crankshaft to align it with the top dead center of the first cylinder, then secure the crankshaft with a fixing screw. 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 specialized 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. The Chery Tiggo 3 features a stylish and high-quality interior, offers a genuine urban off-road SUV driving experience, and comes equipped with the new Cloudrive 2.0 intelligent cloud-connected driving system. In terms of body dimensions, the Tiggo 3 measures 4420mm in length, 1760mm in width, and 1670mm in height, with a wheelbase of 2510mm.

I've looked up the installation procedure for the Tiggo 3 timing belt online, and the specific steps are as follows: First, remove the alternator belt, then take off the crankshaft pulley's fixing bolt. At this point, special attention must be paid to the alignment marks—the marks on the camshaft gear and crankshaft gear must precisely align with the indicators on the engine block; even the slightest misalignment can damage the valves. When installing the new belt, it's best to have two people cooperate: one presses the tensioner pulley while the other feeds the belt into the gear grooves, ensuring the gears don't rotate or shift during the process. Finally, use a specialized tool to adjust the belt tension—too loose and it may skip teeth, too tight and it will accelerate wear. After installation, manually turn the engine two full rotations to confirm the marks still align perfectly before starting. The entire process requires professional tools like a ratchet wrench, belt pliers, and a timing light. It's easy for beginners to make serious mistakes, which is why I didn't dare to attempt it myself after reading the tutorial.

Replaced the timing belt on the Tiggo 3 twice, and the process is quite meticulous. First, remove the accessory belt and the belt guard, remembering to disconnect the negative terminal of the battery to prevent accidental starts. Then locate the crankshaft position sensor and carefully move it aside. The key step is to use a tool to lock the camshaft in place to prevent it from moving—this is where most mistakes happen. Install the new belt in the direction of engine rotation, starting from the crankshaft pulley to the water pump, then to the tensioner pulley, and finally onto the camshaft gear. The belt teeth must fully engage with the gear grooves; if half of a tooth is hanging out, it could skip. After installation, check the tension: use a spring scale to pull the middle section of the belt, with a force of around 35 Newtons being ideal. Finally, manually rotate the engine two full turns to see if the timing marks realign before reassembling all components. It’s recommended to replace the water pump along with the timing belt to avoid opening the engine cover a second time.

Installing the timing belt on the Tiggo 3 has its tricks: When aligning the marks, the crankshaft locating pin hole should align with the arrow on the engine casing, and the dot mark on the camshaft should align with the notch on the rear cover. After installing the belt, immediately check the tension by pressing the middle between the two pulleys with your thumb—a 5 mm depression is the standard. Always use brand-new bolts for the entire process, as old bolts are prone to stripping. Once installed, manually rotate the crankshaft two full turns and carefully check if the marks are still aligned. If something feels off, the tensioner might not be pressed into place or the belt teeth might not be seated correctly. A poorly installed belt can even bend the valve stems in the worst case, leading to cylinder head removal and costly repairs. It's recommended to inspect the belt for cracks every 60,000 km—prevention is always easier and cheaper.
