Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Wear safety goggles and gloves to protect against coolant exposure.

2. Identify the Leak Source

Use a flashlight to inspect the coolant reservoir, radiator, hoses, and water pump for visible leaks.
If necessary, use a pressure tester to pressurize the cooling system and observe for leaks.

3. Replace Damaged Components

Coolant Reservoir:
- Disconnect the battery (negative terminal).
- Remove the coolant reservoir using socket set.
- Replace with a new reservoir and secure it.
Hoses:
- Use pliers to remove hose clamps from any damaged hoses.
- Replace old hoses with new ones and reattach clamps securely.
Radiator:
- Drain the coolant from the radiator using a drain pan.
- Remove the radiator mounting bolts and hoses.
- Install the new radiator and reconnect all hoses and bolts.
Water Pump:
- Drain the coolant.
- Remove the serpentine belt and unbolt the water pump.
- Clean the mounting surface and install the new water pump with a new gasket.
- Refill the cooling system with the appropriate coolant.

4. Refill and Bleed Cooling System

Refill the cooling system with a mixture of coolant and distilled water.
Run the engine with the radiator cap off until the thermostat opens and air bubbles are expelled.
Replace the radiator cap and check for any additional leaks.
