      Wikipedia's Silhouette article gives LG6 in the first-generation infobox and lists the 3.1 LG6 V6 for 1990–1995, which dates 1990 and 1991 (no listed kit page prints LG6 for those years); 1992–1995 from the single-condition remarks "W/3.1L Engine, LG6" on the engine block heater lines of the optional-equipment weight pages (1993 and 1994 on p.40, 1992 on p.42, 1995 on p.77); the Chevrolet Lumina APV doc adds electronic fuel injection from a powertrain page not cited here; shared U-body code; cited from the Chevrolet Lumina APV kit
