Pontiac Fiero
Coolant capacity & service interval
Pontiac Fiero coolant specifications cover a capacity range of 13-13.3 liters. The data includes two model configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| Fiero 2.5 (1984-1988) |
|
| Fiero 2.8 V6 (1984-1988) |

Additional Notes
- The Pontiac Fiero carries a coolant system capacity of 13 to 13.3 liters across all listed configurations, a volume typical of a complete cooling system service fill rather than a partial top-off.
- Both the 2.5-liter four-cylinder and the 2.8-liter V6 share the same 13 to 13.3 liter capacity range, meaning the engine displacement difference between the two does not produce a variation in coolant volume for the 1984-1988 model years.
- The listed capacity applies under normal use conditions for both engine variants across the full 1984-1988 span.
- A capacity range of 13 to 13.3 liters rather than a single fixed value reflects the minor variation that can occur during a real-world cooling system drain and refill, where residual fluid in passages and the heater core affects the final fill volume.
