Additional Notes
- The Toyota MR2 W20 (EU) cooling system capacity is 13 liters across both the 2.0i and 2.2i engine variants, a volume consistent with a mid-engine layout where coolant routing covers greater distances between the engine bay and any front-mounted components.
- The 2.0i (1990-1999) carries a time-only coolant change interval of 24 months under normal use conditions, meaning mileage accumulation has no bearing on when a flush is due.
- The 2.2i (1991-1999) has a combined interval of 40,000 km or 48 months under normal use, whichever comes first, giving a dual trigger that accounts for both calendar aging and driving activity.
- The 24-month interval on the 2.0i is notably shorter than the 48-month interval on the 2.2i, reflecting a two-year difference in the recommended service frequency between the two engine configurations despite sharing the same 13-liter capacity.
- A 48-month coolant change interval, as specified for the 2.2i, is a relatively extended schedule by the standards of the era, suggesting the cooling system was designed or specified to tolerate longer fluid service life under normal operating conditions.
