Gas Gas EX

Coolant capacity & service interval

Gas Gas EX coolant capacity ranges from 0,95 to 1,2 liters. The service interval is 48 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Type	Specifications
EX 250 (2021- )	Use: Normal Capacity 1,2 liter Change 48 months
EX 450F (2021- )	Use: Normal Capacity 0,95 liter Change 48 months
EX 250F (2020- )	Use: Normal Capacity 0,95 liter Change 48 months
EX 300 (2020- )	Use: Normal Capacity 1,2 liter Change 48 months
EX 350F (2020- )	Use: Normal Capacity 0,95 liter Change 48 months
EX 450F (2020-2020)	Use: Normal Capacity 0,95 liter Change 48 months

The Gas Gas EX 250 carries a 1.2-liter cooling system capacity, the largest among the EX lineup in these specifications, shared with the EX 300.
The EX 250F, EX 350F, and EX 450F all share a 0.95-liter cooling system capacity, a notably smaller volume than the two-stroke EX 250 and EX 300 models.
The difference in coolant capacity between the two-stroke and four-stroke variants reflects the distinct engine architecture of each, with two-stroke engines in the EX 250 and EX 300 requiring a larger coolant volume at 1.2 liters versus 0.95 liters for the four-stroke F-suffix models.
All six EX configurations carry a 48-month coolant change interval under normal use conditions, meaning standard riding environments without the added thermal and mechanical stress associated with severe use.
The EX 450F appears under two separate entries: one covering 2020 and another starting from 2021, both specifying identical values of 0.95 liters and a 48-month change interval, indicating no cooling system specification change between those model years.
The EX 250 entry begins with the 2021 model year, while the EX 250F, EX 300, EX 350F, and EX 450F entries all begin from 2020, placing the EX 250 as the latest introduction among the configurations listed here.
