AMC Gremlin

Coolant capacity & service interval

AMC Gremlin coolant capacity ranges from 6,1 to 13,2 liters. Service intervals include checks at 6400 and 9600 km, with fluid changes required at 12 and 24 months. The data covers 5 configurations.

Additional Notes

  • The AMC Gremlin 304 V8 (1971-1976) carries the largest cooling system capacity across all listed engine configurations at 13.2 liters, which reflects the greater heat rejection demands of a V8 engine compared to the inline six-cylinder variants.
  • The Gremlin 121 (1977-1978) has the smallest listed cooling system capacity at 6.1 liters, consistent with the smaller displacement of a four-cylinder engine requiring less coolant volume to maintain operating temperature.
  • The Gremlin 199 (1970-1971) is the only configuration listing two distinct capacity values: 9 liters for the base cooling system and 10 liters when a heater is included, indicating the heater core adds measurable volume to the total coolant circuit.
  • The Gremlin 232 and the Gremlin 258 share an identical cooling system capacity of 9.9 liters despite differing in displacement, and both carry the same check interval of 9,600 km with a 12-month change interval under normal use conditions.
  • The Gremlin 199 (1970-1971) specifies a coolant change interval of 24 months under normal use, which is twice the 12-month interval listed for the 121, 232, 258, and 304 V8 configurations.
  • The Gremlin 199 (1970-1971) also specifies a check interval of 6,400 km, which is shorter than the 9,600 km check interval shared by all other listed engine configurations.
  • The Gremlin 232 spans the full 1970-1978 model year range covered by the specifications, making it the only engine configuration present across the entire listed production period.
