Solution

1. Preparation

Gather required tools and parts.
Allow the engine to cool completely.
Disconnect the battery to ensure safety while working on electrical components.
Raise the vehicle using a jack and secure it with jack stands.

2. Locate the Leak

Use a flashlight to inspect the coolant reservoir, radiator, and all hoses.
If necessary, perform a pressure test using a cooling system pressure tester to identify hidden leaks.

3. Replace Damaged Components

Coolant Reservoir:
- Remove the coolant reservoir by disconnecting any hoses and securing clips.
- Install the new reservoir and reconnect hoses.
Hoses:
- If any hoses are damaged, loosen the clamps and remove the faulty hose.
- Install the new hose and secure it with clamps, ensuring a tight fit.
Water Pump:
- Remove the serpentine belt and unbolt the water pump.
- Replace the gasket and install the new water pump, tightening the bolts to the manufacturer's specifications.

4. Refill and Bleed the Cooling System

Refill the cooling system with the appropriate coolant mixture (refer to the owner's manual for the correct type).
Bleed the cooling system to remove air pockets by running the engine with the radiator cap off until the thermostat opens.

5. Final Inspection

Start the engine and check for leaks around the repaired areas.
Monitor the coolant levels and temperature gauge during the initial test drive.
