Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather tools and parts required for the repair.

2. Coolant Inspection and Replacement

Tools Required: Socket set, coolant funnel, drain pan, safety goggles.
Sub-steps:
1. Remove the radiator cap and check the coolant level; add coolant if low.
2. If coolant is contaminated or old, drain the old coolant by removing the drain plug at the bottom of the radiator.
3. Refill the radiator with the appropriate type of coolant (consult owner's manual for specifications).
4. Replace the radiator cap securely.

3. Leak Repair

Tools Required: Hose clamps, replacement hoses, gasket sealant.
Sub-steps:
1. Identify and replace any damaged hoses or clamps.
2. If a leak is found at the water pump or radiator, replace the necessary components.
3. For minor leaks, apply gasket sealant as per manufacturer instructions.

4. Air Purging from Cooling System

Tools Required: Coolant funnel, vacuum pump (optional).
Sub-steps:
1. With the radiator cap off, start the engine and allow it to reach operating temperature.
2. Add coolant to the radiator as needed while air bubbles escape.
3. Once the gurgling sound subsides and the coolant stabilizes, replace the radiator cap.
