📖Buick Excelle GT II: bestselling compact saloon requiring regular transmission and cooling upkeep

Launched in 2015, the second-generation Buick Excelle GT quickly became one of China's bestselling compact saloons. Featuring Buick's waterfall grille, a spacious four-door saloon layout and multi-link independent rear suspension, it delivered a remarkably refined driving feel in the budget-conscious segment. Keeping an Excelle GT II running smoothly requires systematic Buick Excelle GT maintenance, targeting engine cooling and transmission fluid maintenance.

Engine choices comprised the naturally aspirated 1.5-litre (L2B) engine and the punchier 1.4-litre (LVK) turbo. Power was channelled through a 5-speed manual, a 6-speed automatic gearbox or a 7-speed dual-clutch transmission on turbo models. The cooling system utilises plastic thermostat housings and radiator tanks that age with heat cycles, while front suspension wishbones bear the brunt of urban potholes.
