Repair Instructions

Step 1: Identify and Replace Leaking Components

Coolant Hoses: If any hoses are cracked or swollen, replace them. Use a hose clamp tool to remove the old hose and install the new one.
Radiator: If the radiator is leaking, it may need to be replaced. Disconnect the battery, drain the coolant, remove the mounting bolts, and replace with a new unit.
Water Pump: If the water pump is leaking, it typically requires removing the timing cover and replacing the pump. Ensure to replace the gasket as well.
Head Gasket: If coolant is leaking internally (white smoke from exhaust or milky oil), a head gasket replacement may be necessary. This is a more complex repair requiring engine disassembly.

Step 2: Refill Coolant

After replacing any damaged components, refill the cooling system with the appropriate Toyota coolant.
Use a funnel to pour coolant into the reservoir and the radiator, if applicable.

Step 3: Bleed the Cooling System

Start the engine and let it idle with the heater set to maximum heat to allow air bubbles to escape.
Monitor the temperature gauge; ensure it remains within the normal range.
Check for leaks again after the engine has reached operating temperature.

Step 4: Final Inspection

After the engine has run for a short period, turn it off and allow it to cool.
Recheck coolant levels and top off if necessary.
Clean any spilled coolant and dispose of old coolant properly.

Conclusion

Following these steps should help you diagnose and repair the coolant leak in your 2020 Toyota Camry. If you are not confident in performing these repairs, consider seeking assistance from a certified automotive technician. Regular maintenance and inspections can help prevent future coolant leaks.
