AMC Pacer
Coolant capacity & service interval
AMC Pacer coolant capacity ranges from 13,2 to 15 liters. Service intervals consist of checks every 12000 km or 8 months and changes every 12 months. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| Pacer V8 (1978-1980) |
|
| Pacer 232 (1975-1980) |
|
| Pacer 258 (1975-1980) |

Additional Notes
- The AMC Pacer 232 and 258 inline-six engines share an identical cooling system capacity of 13.2 liters, indicating no meaningful difference in coolant volume between the two displacement variants despite the 258's larger bore and stroke.
- The Pacer V8, available from 1978-1980, carries a notably larger cooling system capacity of 15 liters, reflecting the greater thermal output and larger block size associated with V8 architecture compared to the inline-six configurations.
- Across all three engine configurations, the coolant check interval is set at 12,000 km or 8 months under normal use conditions, whichever comes first, combining both a distance and a time threshold.
- The coolant change interval for all three configurations is specified at 12 months under normal use conditions, meaning calendar time rather than mileage alone governs the replacement schedule.
- The 8-month check interval arriving before the 12-month change interval creates a built-in mid-cycle inspection point, allowing condition assessment roughly two-thirds of the way through the annual service period.
- The 1.8-liter difference in cooling system capacity between the inline-six engines at 13.2 liters and the V8 at 15 liters is a relevant factor when calculating the correct antifreeze-to-water ratio during a coolant service fill.
