Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Coolant Drain and Remove Components

Sub-steps:
- Drain the coolant from the radiator by opening the drain valve or removing the lower radiator hose.
- Remove any components obstructing access to the thermostat and water pump, such as the air intake duct or fan shroud (if required).
Tools Required: Pliers, drain pan, socket set.

3. Thermostat Replacement

Sub-steps:
- Remove the thermostat housing bolts using the socket set.
- Take out the old thermostat and clean the mating surfaces of the housing.
- Install the new thermostat in the correct orientation and secure the housing with bolts (torque to manufacturer specifications).
Tools Required: Torque wrench, gasket scraper.

4. Water Pump Inspection/Replacement

Sub-steps:
- If needed, disconnect the water pump drive belt and remove the water pump mounting bolts.
- Inspect the old water pump for signs of leaks or failure; replace if necessary.
- Install the new water pump, ensuring proper alignment and secure mounting (torque to manufacturer specifications).
Tools Required: Socket set, belt tensioner tool.

5. Reassemble and Refill Coolant

Sub-steps:
- Reinstall any components that were removed for access.
- Refill the cooling system with the appropriate type and mixture of coolant (consult owner's manual for specifications).
- Bleed the cooling system to remove any air pockets.
Tools Required: Funnel, coolant.
