Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Coolant System Inspection

Sub-steps:
1. Remove the engine cover if applicable.
2. Inspect all hoses connected to the radiator and engine for signs of wear or leaks.
3. Replace any damaged hoses with new ones.
4. Check the radiator for blockages or damage; clean or replace as necessary.

3. Thermostat Replacement

Sub-steps:
1. Locate the thermostat housing and unbolt it using a socket set.
2. Remove the old thermostat and clean the mounting surface.
3. Install the new thermostat in the correct orientation.
4. Reattach the thermostat housing and torque the bolts to the manufacturer's specification.

4. Water Pump Inspection/Replacement

Sub-steps:
1. Remove any components obstructing access to the water pump.
2. Disconnect the hoses from the water pump.
3. Unbolt the water pump from the engine block and remove it.
4. Install the new water pump and torque the bolts to specifications.
5. Reconnect the hoses ensuring there are no leaks.

5. Refill Coolant System

Sub-steps:
1. Use a funnel to refill the coolant reservoir with the recommended coolant type.
2. Bleed the cooling system to remove any air pockets by running the engine with the radiator cap off until the thermostat opens.
3. Replace the radiator cap securely once the system is bled.
