2 Answers
The firing order of the Buick Excelle is 1-3-4-2. Here are some relevant details about the Buick Excelle: 1. Positioning: The Buick Excelle is positioned as an entry-level family car, featuring a dynamic exterior and high-quality interior, offering a premium experience for "your first car." The all-new drivetrain ensures smooth performance and fuel efficiency. It also comes standard with the 10th-generation OnStar assistant, providing full-time connectivity, a built-in 4G-LTE mobile hotspot, and eConnect smart connectivity technology supporting Apple CarPlay and Baidu CarLife. 2. Exterior: The new-generation Excelle adopts Buick's latest family design language, featuring the brand's signature winged grille with dark mesh texture and a high-gloss chrome-plated shield-shaped outer contour, exuding youthful vitality. The winged headlights and grille form a dynamic, diving angle, enhancing the sporty appearance.
As a mechanic with years of experience, the ignition coil sequence for the Buick Excelle is typically 1-3-4-2, designed for four-cylinder engines. The exact model depends on the year, like the older 1.6L engine which follows this order. Why is the sequence important? Because precise ignition timing ensures synchronized combustion in the engine. If the order is messed up, the car will shake like an earthquake, lose acceleration power, and could even damage spark plugs or sensors. During routine maintenance, I use marking methods to check coil wiring, ensuring each one corresponds to the correct cylinder. If the engine warning light comes on, don't force it—check the manual or visit a professional shop first. After all, the ignition system is the core, and proper maintenance can extend the vehicle's lifespan.
