Additional Notes
- The Nissan Altima L31 (USA) cooling system holds 7.6 liters across both the 2.5 and 3.5 engine variants for the 2002-2006 model years, a figure that reflects the total system fill volume rather than a partial or overhaul-specific quantity.
- Under normal use conditions, the coolant change interval for the 2.5 engine is 30,000 miles or 24 months, whichever comes first, placing routine service on a two-year cycle.
- A first change only interval of 60,000 miles or 48 months applies to the 2.5 engine, meaning the initial factory-fill coolant is rated for a longer service life before the standard normal-use schedule takes over.
- The 3.5 engine shares the same normal-use interval of 30,000 miles or 24 months as the 2.5, with the 7.6-liter capacity remaining identical between the two engine configurations.
- The first change only interval for the 3.5 engine is also 60,000 miles or 48 months, consistent with the extended initial service life specified for the 2.5 engine under the same condition.
- The identical 7.6-liter cooling system capacity across both the 2.5 and 3.5 engines for 2002-2006 indicates no variation in system volume despite the difference in engine displacement between the two configurations.
