How to Install the Timing Belt on a Excelle?
3 Answers
The installation method for the Excelle timing belt is as follows: 1. Align the timing mark on the crankshaft timing gear with the notch at the bottom of the rear timing belt cover; 2. Align the timing marks on the camshaft timing gears, then install the timing belt and the right engine mount bracket; 3. Rotate the water pump clockwise until the pointer on the timing belt automatic tensioner aligns with the notch on the tensioner bracket. The Excelle has a length of 4468mm, width of 1765mm, height of 1469mm, a wheelbase of 2611mm, and is equipped with an engine that delivers a maximum horsepower of 107hp, maximum power of 79kW, and maximum torque of 133Nm.
Installing the timing belt on a Buick Excelle is a technical job that requires patience and the right tools. Last time I helped my neighbor with it, we had to remove the engine cover first and use a lift or jack to raise the car for easier access. Check the alignment marks on the crankshaft and camshaft, and only remove the old belt after ensuring they're properly aligned. When installing the new belt, make sure the tension is just right—not too loose or too tight, as it can easily slip off. After adjusting the tension with a tension gauge, manually turn the engine two full rotations to check if the marks still align. The whole process can't be rushed; if the timing belt isn't installed correctly, it can lead to valve damage or even engine failure. It's recommended to inspect it every 60,000 km, and it's best to consult a professional or refer to the vehicle's manual. If you're doing it yourself, have wrenches and a work light ready, be careful not to cut your hands, and expect it to take about two hours.
I think the installation of the Excelle timing belt should be done step by step. Before starting, turn off the engine and let it cool for a while—safety first. Remove the air filter and fan cover, locate the belt tensioner, loosen it, and take out the old part. Remember the position of the timing marks; the alignment of the crankshaft and camshaft marks is crucial for the entire engine's operation. When installing the new belt, handle it gently to avoid twisting, and adjust the tension with a wrench—it should rotate about 90 degrees. Finally, manually rotate the crankshaft to check synchronization. If everything is fine, reassemble all components. Regular belt replacement is essential—if the Excelle's belt ages and isn't replaced, it can skip teeth and damage the engine. If you're doing it yourself, find a helper for lighting, wear protective gear, and don’t rush the process—it usually takes about half a day.
