Solution

1. Preparation

Gather tools and parts needed.
Ensure the engine is cool before starting.
Disconnect the battery to prevent any electrical issues.

2. Locate the Leak

Use a flashlight to inspect the cooling system components, focusing on potential leak points identified in the diagnostic steps.
Clean the area around suspected leaks with a rag to identify fresh coolant.

3. Repair or Replace Components

A. If a hose is leaking:

Loosen the hose clamps with a screwdriver.
Remove the damaged hose and replace it with a new one.
Tighten the clamps securely.

B. If the water pump is leaking:

Drain the coolant from the radiator.
Remove the serpentine belt by loosening the tensioner.
Unscrew and remove the water pump from the engine.
Clean the mounting surface and install a new water pump with a new gasket.
Reinstall the serpentine belt and refill the cooling system with fresh coolant.

C. If the radiator is leaking:

Drain the coolant from the radiator.
Remove the upper and lower radiator hoses.
Unscrew the radiator mounting brackets and carefully remove the radiator.
Install the new radiator and reconnect all hoses.
Refill the system with coolant.

4. Refill the Cooling System

Use a funnel to pour the correct type of coolant into the reservoir.
Start the engine and let it idle with the heater on to allow air to escape from the system.
Continue to monitor the coolant level and add more as necessary.
