Additional Notes
- The Chevrolet Corvette C4 (USA / CAN) cooling system capacity is 15.8 liters across all listed configurations, spanning the standard 5.7 V8 variants and the ZR-1.
- A 15.8-liter coolant capacity is consistent with a large-displacement V8 engine, reflecting the volume required to fill the engine block, cylinder heads, radiator, heater core, and associated hoses.
- The 5.7 V8 configurations covering 1985-1991, 1989-1991, and 1991-1996 all share identical service specifications, with a check interval of 12,500 km and a change interval of 48,000 km or 24 months, whichever comes first.
- The ZR-1, produced from 1989-1995, carries the same 15.8-liter capacity and the same 12,500 km check and 48,000 km / 24-month change intervals as the standard 5.7 V8 models.
- The 24-month time limit on the coolant change interval means a calendar-based threshold applies regardless of distance traveled, which is relevant for low-mileage vehicles that may not reach 48,000 km within two years.
- The 12,500 km check interval is shorter than the 48,000 km change interval, indicating that coolant condition and level are to be inspected periodically between full drain-and-fill services.
