Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting.
Disconnect the battery for safety.

2. Locate and Repair the Leak

Sub-step 1: If a leaking hose is found, loosen the clamps and remove the hose. Replace with a new hose of the same size and type.
Sub-step 2: If the radiator is leaking, drain the coolant using a draining pan, remove the radiator, and replace it with a new unit.
Sub-step 3: For a leaking water pump, drain the coolant, remove the serpentine belt, and unbolt the water pump. Replace it with a new pump and ensure to use new gaskets.
Sub-step 4: Reconnect any hoses and ensure all clamps are securely tightened.

3. Refill the Cooling System

Sub-step 1: Refill the coolant reservoir with the appropriate type and mixture of coolant (refer to the owner's manual for specifications).
Sub-step 2: Start the engine and allow it to reach operating temperature, monitoring the system for leaks.

4. Final Checks

Sub-step 1: After the engine has cooled, recheck the coolant level and top off if necessary.
Sub-step 2: Inspect the area around the repaired components for any signs of leaks.
