Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and materials.
Wear gloves and safety goggles for protection.

2. Inspect Air Conditioning System

Sub-steps:
1. Turn on the air conditioning system to full blast.
2. Observe if the puddle increases in size; this indicates normal condensation.
3. If the puddle does not increase, proceed to check for leaks.

3. Check Coolant System

Sub-steps:
1. Allow the engine to cool completely.
2. Open the hood and check the coolant reservoir for adequate fluid levels.
3. Inspect the radiator and hoses for any visible leaks.
4. If low coolant is found, add the appropriate coolant mix (typically a 50/50 blend of water and antifreeze).

4. Inspect Heater Core

Sub-steps:
1. If coolant levels are normal, check the passenger side footwell for dampness, which could indicate a leaking heater core.
2. If dampness is present, further investigation or replacement of the heater core may be needed.

5. Final Inspection

Sub-steps:
1. Ensure all hoses are securely connected and not damaged.
2. Tighten any loose clamps and replace any damaged hoses if necessary.

Tools Required:

Screwdrivers
