Trim / Codes
The 1998 Q45 carried over the second-generation model introduced for 1997, powered by a 4.1-liter V8 mated to a four-speed automatic transmission, with the Q45t trim offering a firmer suspension and additional equipment. Changes for 1998 were minimal, as the redesign was only a year old. Common service considerations include timing belt replacement on the interference V8, regular transmission fluid service, and inspection of aging suspension and electrical components. Higher-mileage examples may also exhibit oil consumption and alternator failures.
