Additional Notes
- Both the 2.0 16V and 2.5 V6 24V engines share an identical manual transaxle fluid capacity of 2.6 liters, indicating a common transmission unit across the two engine configurations available in the Mercury Cougar from 1998-2002.
- A 2.6-liter capacity is consistent with a compact front-wheel-drive manual transaxle, where the gearbox and differential share a single fluid reservoir rather than separate sumps as found in rear-wheel-drive layouts.
- The service interval for the manual transaxle fluid is specified as a check every 6 months, applying under normal use conditions for both the 2.0 16V and 2.5 V6 24V variants across the full 1998-2002 model range.
- A 6-month check interval, rather than a defined replacement interval, reflects a monitoring-based approach where fluid condition and level are assessed periodically rather than changed on a fixed schedule under normal use.
