Solution

1. Preparation

Gather tools and parts needed for the inspection.
Ensure the engine is cool before starting.
Disconnect the battery to avoid electrical issues.

2. Visual Inspection

Remove any obstructions to access the water pump.
Inspect the water pump and surrounding area for signs of coolant leaks, rust, or corrosion.
Check the condition of hoses connected to the pump for cracks or wear.

3. Coolant Level Check

Open the coolant reservoir cap and check the coolant level.
If low, fill with the appropriate coolant mixture (Toyota Long Life Coolant recommended).

4. Noise Inspection

Start the engine and allow it to reach operating temperature.
Listen closely around the water pump for any abnormal noises, such as grinding or whining.
If noises are detected, the water pump may need replacement.

5. Check for Pulley Movement

After turning off the engine, manually rotate the water pump pulley.
Check for smooth operation and excessive play; any wobbling may indicate a failing pump.
