If the fluid is hot (70C ± 90C or 158F ±194F), the level
should be in the ºHOTº range. Similarly, if it is cold (10 C
± 30 C or 50F ± 86F), the level should be in the ºCOLDº
range. If the level is at the low side of either range, add
automatic transmission fluid DEXRON
 II or III to bring the
level within the range.
CAUTION
The reservoir may be hot so be careful not to burn yourself.
NOTICE
When adding the engine fan fluid, avoid overfilling.
