Solution

1. Preparation

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

2. Locate the Leak

Use a pressure tester on the cooling system to identify the source of the leak.
Visually inspect all components while under pressure to detect any escaping coolant.

3. Repair or Replace Affected Components

Coolant Reservoir: If cracked, replace with a new reservoir. Remove the old reservoir, install the new one, and secure it with mounting clips.
Hoses: If damaged, replace the affected hose(s). Loosen the clamps, remove the hose, and install a new one, ensuring it is properly secured.
Radiator: If leaking, replace the radiator. Disconnect the hoses, remove mounting brackets, and install the new radiator, reconnecting all hoses.
Water Pump: If leaking, replace the water pump. Drain coolant, remove the pump, install the new one, and refill the coolant system.
Head Gasket: If leaking, this requires more extensive work. Remove the cylinder head, replace the gasket, and reassemble the engine with proper torque specifications.

4. Refill and Bleed the Cooling System

Refill the cooling system with the appropriate coolant mixture.
Bleed the system of air bubbles by running the engine with the cap off until the thermostat opens and coolant circulates.
