Specific Gravity Check
WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
- Read hydrometer and thermometer indications at eye level.
- Use Hydrometer Temperature Correction to correct your hydrometer reading according to electrolyte temperature.
