Trim / Codes

The 1999 Nissan G20 marked the model's return to the U.S. market after a two-year absence, built on the Nissan Primera platform with a 2.0-liter SR20DE four-cylinder engine. Changes for the model year were relatively minor, with the sedan offered in base and SE trim levels. Common service considerations include timing chain tensioner wear, oil leaks around the valve cover and cam seals, and inspection of the timing chain at higher mileage. The SR20DE engine requires premium fuel and consistent oil changes to maintain reliability.

  The 1999 Nissan G20 is a front-wheel-drive compact sedan powered by a 2.0-liter SR20DE inline-four engine, offered with either a five-speed manual or four-speed automatic transmission. Because the SR20DE is an interference engine, timing belt replacement at the manufacturer's recommended interval is critical, with the water pump and belt tensioner commonly serviced at the same time. Typical maintenance focus includes valve cover and oil pan gasket leaks, spark plug and ignition coil service, and oxygen sensor replacement. Automatic transmission fluid changes and suspension wear items such as struts, ball joints, and control arm bushings are also common service areas.
