Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the engine to cool completely before starting.

2. Drain Coolant

Place a drain pan under the radiator.
Open the radiator drain valve and allow coolant to drain completely.
Dispose of old coolant according to local regulations.

3. Replace Damaged Components

3.1 Hoses

Identify and remove any damaged hoses.
Replace with OEM or high-quality aftermarket hoses.
Secure clamps and ensure there are no kinks.

3.2 Water Pump

Remove the drive belt by releasing tension using a wrench.
Unbolt the water pump from the engine block.
Clean the gasket surface and install a new water pump with a new gasket.
Reinstall the drive belt and ensure proper tension.

3.3 Radiator

Remove the radiator by disconnecting the upper and lower hoses, and any mounting brackets.
Install a new radiator, ensuring all connections are secure and leak-free.

4. Refill Coolant

Close the radiator drain valve.
Mix the appropriate coolant (50/50 mix of antifreeze and distilled water if required) and fill the radiator and reservoir to the recommended levels.
Run the engine with the heater on to purge air from the system.

5. Final Inspection

Check for leaks around all replaced components.
Monitor coolant levels after a few days of operation.
