Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, coolant pressure tester, socket set, torque wrench
Ensure the engine is cool before starting work to avoid burns.

2. Inspect and Replace Hoses

Sub-steps:
1. Remove any engine covers if necessary.
2. Inspect each coolant hose for cracks or leaks.
3. If a hose is damaged, use a socket set to remove the clamps and detach the hose.
4. Install a new hose by sliding it onto the fitting and securing it with clamps. Ensure clamps are tightened to the manufacturer's torque specifications.

3. Examine the Radiator

Sub-steps:
1. Visually inspect the radiator for any signs of leaks or corrosion.
2. If leaks are found, drain the coolant from the radiator using the drain plug (if equipped).
3. Remove the radiator using the socket set and replace it with a new one.
