Solution

1. Preparation

Gather tools: socket set, screwdrivers, coolant, and safety gloves.
Park the vehicle on a level surface and ensure the engine is cool before starting work.

2. Inspect and Replace Coolant

Open the hood and locate the coolant reservoir.
Sub-steps:
1. Remove the cap from the coolant reservoir.
2. If low, add the appropriate type of coolant as specified in the owner's manual.
3. Check for proper coolant-to-water ratio if using concentrated coolant.

3. Check and Repair Cooling System Components

Sub-steps:
1. Inspect the radiator for any obstructions; clean if necessary.
2. Check all hoses for cracks or leaks; replace if damaged.
3. Test the cooling fans by turning on the vehicle and observing their operation.
4. If fans do not engage, check wiring connections and replace the fan motor if needed.

4. Pressure Test the Cooling System

Sub-steps:
1. Use a cooling system pressure tester to check for leaks.
2. Pressurize the system to the recommended PSI and observe for drops in pressure, indicating leaks.
3. Repair any identified leaks, which may involve replacing gaskets or hoses.
