Additional Notes
- The Honda Accord III CA cooling system capacity varies by transmission type across all listed configurations, holding 6.9 liters with an automatic transaxle and 6.3 liters with a manual transaxle.
- The 0.6-liter difference between automatic and manual transaxle configurations reflects the additional coolant volume routed through the automatic transmission fluid cooler, which is typically integrated into the radiator on vehicles of this era.
- The DX, LX, and LXi trims spanning 1986-1989 share identical coolant capacities for both transaxle types, meaning trim level alone does not influence cooling system fill volume.
- The Accord III LXi appears across two overlapping row entries, one covering 1986-1987 and another covering 1987-1989, with both entries carrying the same 6.9-liter and 6.3-liter capacities and the same service interval.
- The specified coolant change interval for all listed configurations under normal use conditions is 48,000 miles or 48 months, whichever comes first, reflecting a four-year or roughly 77,000-kilometer service cycle.
- A 48-month coolant change interval aligns with the service life of ethylene glycol-based antifreeze formulations common in the mid-to-late 1980s, which were not extended-life coolants and required more frequent replacement than modern long-life formulas.
