- Inspect the area around the water pump for wetness or residue.
- If leaking, replace the water pump.

3. Repair or Replace Affected Parts

Radiator Replacement
- If the radiator is cracked, drain the coolant, disconnect hoses, and replace it.
Hose Replacement
- Cut off damaged sections of hoses and replace with new hoses; secure with clamps.
Water Pump Replacement
- Drain the coolant, remove the water pump, clean the gasket surface, and install a new pump with a new gasket.

4. Refill and Test

Refill the cooling system with the appropriate coolant type.
Start the engine and let it idle to check for leaks.
Monitor temperature gauge for any signs of overheating.
