Capacity by engine option

Flush interval

For a 2022 Toyota Corolla, the initial coolant flush is recommended at 100,000 miles or 10 years, whichever comes first. Subsequent flushes should be performed every 50,000 miles or 5 years. Severe duty driving (e.g., frequent short trips, extreme temperatures, dusty conditions) may necessitate more frequent changes.

How to refill & bleed

1. Ensure the engine is cool.
2. Locate the radiator cap and coolant reservoir.
3. To add coolant, slowly pour a 50/50 pre-mixed solution of Toyota SLLC into the reservoir until it reaches the "FULL" line.
4. To bleed the system, with the reservoir cap off, start the engine and let it run until it reaches operating temperature. You will see the coolant level in the reservoir drop as air is purged from the system. Top off the reservoir as needed. Some models may have a bleed screw on the thermostat housing to assist with this process. Using a vacuum-fill tool is the most effective way to prevent air pockets.

Common cooling system issues

The 2022 Toyota Corolla is a relatively new model, and widespread cooling system issues have not been reported. However, some common problems on modern vehicles to watch for include:

• Water pump failure: A failing water pump can cause coolant leaks and overheating.
• Thermostat issues: A stuck thermostat can lead to the engine either overheating or not reaching operating temperature.
• Radiator leaks: Debris or damage can cause leaks in the radiator, leading to coolant loss.
