Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Leaks

Coolant Reservoir:
- Remove the reservoir cap and inspect for cracks or damage.
- Replace the reservoir if damaged.
Hoses and Connections:
- Inspect each hose from the radiator to the engine for cracks or soft spots.
- Tighten any loose clamps; replace hoses that show signs of wear.
Radiator Inspection:
- Check for any visible leaks or corrosion on the radiator.
- Replace the radiator if any damage is found.
Water Pump Check:
- Inspect the water pump for leaks around the weep hole.
- Replace the water pump if any leakage is present.

3. Refill and Bleed the Cooling System

Refilling Coolant:
- Use a 50/50 mix of Toyota-approved coolant and distilled water.
- Fill the coolant reservoir to the recommended level.
Bleeding the System:
- Start the engine and allow it to reach operating temperature.
- Open the bleed valve (if equipped) to release trapped air until coolant flows out.
- Close the valve and ensure the coolant level is correct.
