Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical issues.

2. Locate the Leak

Tools Required: Pressure tester, flashlight, coolant catch pan.
Pressurize the cooling system with the pressure tester and observe for leaks.
Use the flashlight to inspect areas where coolant may be leaking.

3. Replace Damaged Components

Hoses:
- Loosen hose clamps using a socket set.
- Remove the damaged hose.
- Install the new hose and tighten clamps to manufacturer's specifications.
Radiator:
- Drain coolant into a catch pan.
- Remove the mounting bolts for the radiator.
- Disconnect the transmission cooler lines if applicable.
- Lift the radiator out and install a new radiator, reversing the removal steps.
Water Pump:
- Drain coolant from the system.
- Remove the serpentine belt using a wrench to relieve tension.
- Unbolt the water pump from the engine block and remove it.
- Clean the mating surface and install the new water pump with a new gasket.
- Torque the bolts to the manufacturer's specifications.

4. Refill and Bleed the Cooling System

Fill the coolant reservoir with the specified coolant type.
Start the engine and allow it to reach operating temperature with the radiator cap off to bleed air from the system.
Monitor the temperature gauge and check for leaks during this process.
