Solution

1. Preparation

Gather tools and parts required for the repair.
Allow the engine to cool completely before starting work.
Disconnect the battery to prevent any electrical issues.

2. Replace Thermostat

Remove the thermostat housing bolts using a socket set (typically 10mm).
Carefully lift the thermostat out, noting its orientation.
Clean the gasket surface on the engine block and the thermostat housing.
Install the new thermostat ensuring it is oriented correctly.
Reattach the thermostat housing and torque bolts to the manufacturer’s specifications (consult service manual for exact torque values).

3. Repair or Replace Water Pump

Remove the serpentine belt from the water pump by using a socket wrench to release the tensioner.
Disconnect any hoses attached to the water pump.
Remove the water pump mounting bolts and carefully take out the old pump.
Clean the mounting surface on the engine block.
Install the new water pump, ensuring proper alignment and torque the mounting bolts to specification.
Reattach hoses and the serpentine belt.

4. Flush and Refill Cooling System

Place a drain pan under the radiator and open the drain valve to remove old coolant.
Once drained, close the valve and refill the radiator with a 50/50 mix of recommended coolant and distilled water.
Start the engine and allow it to reach operating temperature while checking for leaks.
Top off coolant as necessary and run the engine with the heater on to purge air from the system.
