Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the engine is cool to avoid burns.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Thermostat

Tools Required: Socket set, Torque wrench, Gasket scraper
Remove the thermostat housing by unscrewing the bolts (use the torque wrench to avoid over-tightening).
Carefully remove the old thermostat and clean the mating surfaces.
Install the new thermostat (ensure it is oriented correctly) and replace the gasket.
Torque the thermostat housing bolts to specifications (typically around 10-15 Nm, but check the specific manual for your model).

3. Check and Replace Coolant

Tools Required: Coolant funnel, Drain pan
Place a drain pan under the radiator and open the drain valve to remove old coolant.
Flush the cooling system with water until clean (if necessary).
Close the drain valve and refill with the manufacturer-recommended coolant mixture (50/50 water and antifreeze).
Run the engine with the radiator cap off until the thermostat opens, allowing air to escape.

4. Inspect and Repair Cooling System Components

Tools Required: Multimeter, Various hand tools
Check the cooling fans for proper operation; replace if non-functional.
Inspect all hoses for signs of wear, leaks, or blockages and replace as needed.
Ensure the radiator is free of debris and not clogged.
