Solution

1. Preparation

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

2. Coolant Level Adjustment

Remove the coolant reservoir cap.
If low, add the manufacturer-recommended coolant mixture to the appropriate level.
Re-secure the cap.

3. Thermostat Replacement

Locate the thermostat housing (typically found where the upper radiator hose connects to the engine).
Remove the bolts securing the thermostat housing using a socket set.
Carefully remove the housing and the old thermostat.
Clean the mating surfaces with a scraper to remove old gasket material.
Install the new thermostat (ensure it is oriented correctly) and replace the housing with new gasket material.
Torque the bolts to the manufacturer’s specification.

4. Water Pump Inspection and Replacement

Remove any components obstructing access to the water pump (if necessary).
Disconnect the hoses attached to the water pump.
Remove the mounting bolts using a socket set.
Take out the old water pump and inspect the mounting surface.
Install the new water pump, ensuring proper alignment and torque specifications are followed.
Reconnect hoses securely.

5. Radiator and Fan Inspection

Inspect the radiator for any debris; clean it with a soft brush or compressed air.
Check the radiator fan's connection and ensure it is functioning by testing its operation.
Replace the fan if it does not engage when the engine reaches operating temperature.

6. System Bleeding

After all repairs, refill the coolant system and start the engine with the cap off.
Allow the engine to reach operating temperature, and watch for air bubbles in the coolant.
Once the bubbles are gone, replace the cap securely.
