Additional Notes
- The Mercury Topaz cooling system capacity of 7.6 liters applies across all listed configurations, covering the 4WD, GS, LS, XR5, and LTS trims.
- A 7.6-liter cooling system capacity is a service fill figure, representing the total volume of coolant the system holds during a standard drain-and-refill procedure.
- The normal use interval for coolant changes is set at 48,000 miles or 36 months, whichever comes first, across all three configurations.
- The 36-month time limit on the coolant change interval reflects the chemical degradation of antifreeze additives over time, which occurs independently of mileage accumulation.
- The 4WD configuration carries the same 7.6-liter capacity and 48,000-mile interval as the front-wheel-drive GS, LS, XR5, and LTS trims, indicating no cooling system volume difference tied to the drivetrain type.
- The GS and LS trim specifications cover the 1988-1994 model years, while the 4WD and XR5/LTS configurations share a 1988-1992 span, with all rows referencing identical capacity and interval values.
