The 2019 Toyota Corolla cooling system holds approximately 6.9 quarts (6.5 liters) of Toyota Super Long Life Coolant (SLLC) for the 1.8L 2ZR-FAE engine and 7.2 quarts (6.8 liters) for the 2.0L M20A-FKS engine.
Quick Answer
- Total Cooling System Capacity: 6.9 – 7.2 quarts (6.5 – 6.8 liters)
- OEM Coolant Spec: Toyota Super Long Life Coolant (SLLC), pink, Pre-diluted Hybrid Organic Acid Technology (HOAT).
- Mix Ratio: Pre-mixed 50/50 ethylene glycol solution.
Capacity by Engine Option
| Engine | Capacity (Quarts) | Capacity (Liters) |
|---|---|---|
| 1.8L 2ZR-FAE | 6.9 | 6.5 |
| 2.0L M20A-FKS | 7.2 | 6.8 |
Flush Interval
Toyota recommends the first coolant flush at 100,000 miles (160,000 km) or 10 years, whichever comes first. Subsequent flushes are recommended every 50,000 miles (80,000 km) or 5 years. For severe duty, it's wise to consider shortening these intervals, perhaps by 25-50%, especially if you frequently drive in extreme temperatures, tow, or operate in dusty conditions.
How to Refill & Bleed
Refilling and bleeding the cooling system on a 2019 Toyota Corolla is a straightforward process, but proper air removal is crucial to prevent overheating.
- Drain the old coolant: Locate the drain plug on the bottom of the radiator and open it. Ensure the engine is cool before doing this. Some models may have an additional drain on the engine block.
- Close the drain and refill: Once drained, close the radiator drain plug. Slowly pour new Toyota SLLC into the radiator overflow reservoir up to the "FULL" line.
- Bleed the system: Start the engine with the radiator cap off (or reservoir cap if filling through the reservoir). Let it run and reach operating temperature with the heater on full blast. This helps open the thermostat and circulate coolant through the heater core. Watch for air bubbles rising to the surface. Gently squeeze the upper and lower radiator hoses to dislodge air pockets.
- Top up: As air escapes, the coolant level will drop. Continue to add coolant to maintain the proper level. Once no more bubbles appear and the fan cycles on and off a few times, replace the radiator cap or reservoir cap.
- Final check: After driving, let the engine cool down and recheck the coolant level in the overflow reservoir. Top up as necessary.
Note: The 2019 Toyota Corolla typically does not have a specific bleed screw. The self-bleeding design relies on the radiator cap and expansion tank to release air. A vacuum fill tool can expedite the process and ensure a thorough air bleed, especially after a complete system drain.
