Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Inspect and Replace Hoses

Sub-steps:
1. Disconnect the battery (negative terminal) for safety.
2. Visually inspect all coolant hoses for cracks or soft spots.
3. If any hoses are damaged, use a socket set to remove the clamps and replace the hoses.
4. Tighten new hose clamps to manufacturer specifications.

3. Pressure Test the Cooling System

Sub-steps:
1. Attach a coolant pressure tester to the radiator cap opening.
2. Pump the tester to the specified pressure (usually 15-20 psi).
3. Observe for any drops in pressure and visually inspect for leaks.
4. If leaks are found, identify the source and proceed to repair or replace the affected component.

4. Inspect and Replace the Water Pump

Sub-steps:
1. Remove any components obstructing access to the water pump (if necessary).
2. Inspect the water pump for coolant leaks around the weep hole.
3. If leaking, drain the coolant, remove the pump using a socket set, and replace it with a new water pump.
4. Refill the system with the appropriate coolant and check for leaks.
