Trim / Codes
The 1989 model year introduced the S13-generation 240SX, replacing the 200SX with the KA24E 2.4-liter single overhead cam four-cylinder engine rated at 140 horsepower, offered as a hatchback or notchback coupe with pop-up headlights. The 1990 model year was largely a carryover with only minor equipment and trim adjustments. Common service considerations for these cars include timing chain and tensioner wear, oil leaks from the valve cover and rear main seals, aging suspension bushings, and cooling system maintenance on high-mileage examples.
