Solution

1. Preparation

Tools Required: Socket set, coolant pressure tester, funnel, safety gloves, safety goggles.
Ensure the engine is cool before beginning any work on the cooling system.

2. Add Coolant

Locate Coolant Reservoir: Find the coolant reservoir under the hood.
Remove Cap: Carefully remove the cap from the coolant reservoir.
Add Coolant: Using a funnel, add the appropriate type of coolant (check owner's manual for specifications) until it reaches the appropriate level.
Replace Cap: Securely replace the cap on the coolant reservoir.

3. Inspect and Repair Leaks

Visual Inspection: Thoroughly inspect all hoses and connections for any signs of wear or leaks.
Repair or Replace: If leaks are found in hoses, replace the affected hoses. For leaks in the radiator or engine block, consider sealing or replacing the components as necessary.
Pressure Test: After repairs, use the coolant pressure tester to ensure no further leaks are present.

4. Flush Cooling System (if necessary)

Drain Old Coolant: Locate the drain plug on the radiator and allow old coolant to drain into a suitable container.
Flush System: Use a flushing agent if required, or simply run water through the system until it runs clear from the drain plug.
Refill with New Coolant: After flushing, refill the system with the correct type of coolant as per manufacturer specifications.
