Solution

1. Preparation

Tools Required: Socket set, screwdrivers, multimeter, coolant funnel.
Allow the engine to cool before starting any work to prevent burns.

2. Check Coolant Levels

Remove the coolant reservoir cap.
If the coolant is low, refill it to the proper level with the manufacturer-recommended coolant type.

3. Inspect and Replace the Thermostat

Tools Required: Socket set, gasket scraper, torque wrench.
Remove the thermostat housing bolts and detach the housing.
Take out the old thermostat and inspect it for proper operation. If stuck closed, replace it with a new thermostat.
Clean the mating surfaces and install the new thermostat with a new gasket.
Tighten the housing bolts to the manufacturer's specified torque.

4. Inspect and Repair Radiator and Hoses

Visually inspect the radiator for blockages or damage.
Check all hoses for signs of wear, cracks, or leaks. Replace any damaged hoses.
If the radiator is obstructed, flush the radiator with a suitable cleaning solution.

5. Test and Replace Radiator Fan

Use a multimeter to check the fan motor for continuity.
If the fan does not operate, replace it with a new unit.
Ensure that the fan's wiring is intact and secure.

6. Final Assembly and Coolant Refill

Reassemble any components removed during the process.
Refill the cooling system with the appropriate coolant mixture.
Bleed the cooling system to remove any air pockets.
