Solution

1. Preparation

Tools Required: Socket set, screwdriver set, coolant pressure tester, drain pan.
Gather necessary replacement parts such as hoses, clamps, or a water pump if required.
Ensure the engine is cool and disconnect the negative battery terminal.

2. Drain Coolant

Place a drain pan under the radiator.
Open the radiator drain valve or remove the lower radiator hose to drain the coolant completely.
Dispose of the old coolant according to local regulations.

3. Identify and Replace Leaking Components

Hoses:
- Inspect each hose for cracks or bulges.
- Use a socket to remove hose clamps and disconnect the damaged hose.
- Install the new hose and secure with clamps, tightening to manufacturer specifications (typically around 10-15 Nm).
Radiator:
- If the radiator is leaking, remove it by disconnecting the upper and lower hoses and the mounting brackets.
- Install the new radiator and reconnect hoses, ensuring all connections are tight.
Water Pump:
- If the water pump is leaking, remove the serpentine belt using a wrench on the tensioner pulley.
- Remove the water pump bolts and lift out the old pump.
- Clean the mounting surface and install the new pump with a new gasket, torqueing bolts to manufacturer specifications (typically around 10-15 Nm).

4. Refill Cooling System

Close the drain valve or reconnect the lower radiator hose.
Refill the cooling system with the appropriate type and mixture of coolant as specified in the owner's manual.
Run the engine with the radiator cap off until the thermostat opens and air bubbles escape, then replace the cap.

5. Test System

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature while monitoring for leaks.
Check the coolant level again and top off if necessary.
