Ensure the engine is cool and disconnect the battery.
Place a drain pan under the radiator.

2. Identify the Leak

Sub-step 1: Use a pressure tester on the cooling system to pressurize it and locate the source of the leak.
Sub-step 2: Mark any visible leaks for repair.

3. Repair or Replace Affected Components

Sub-step 1: If a hose is leaking, loosen the clamps and remove the damaged hose. Replace it with a new hose and secure it with clamps.
Sub-step 2: If the radiator is leaking, remove the mounting bolts, disconnect the hoses, and replace it with a new radiator.
Sub-step 3: For a leaking water pump, drain the coolant, remove the water pump by disconnecting hoses and bolts, and install a new water pump with a new gasket.

4. Refill Coolant

Sub-step 1: Refill the cooling system with the appropriate coolant type as specified in the owner's manual.
Sub-step 2: Bleed the cooling system to remove any air pockets.

5. Final Checks

Sub-step 1: Reconnect the battery.
Sub-step 2: Start the engine and allow it to reach operating temperature while monitoring for leaks.
Sub-step 3: Check the coolant level after the engine has cooled down and top off if necessary.
