Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect Cooling System

Tools Required: Socket set, screwdrivers, coolant pressure tester
Remove the engine cover if applicable.
Inspect all coolant hoses for cracks or leaks; replace any damaged hoses.
Check the radiator for any signs of blockage or damage.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, gasket scraper, torque wrench
Drain the coolant by opening the drain valve on the radiator.
Remove the thermostat housing (usually located at the engine end of the upper radiator hose).
Take out the old thermostat and replace it with a new one.
Clean the mating surfaces and install a new gasket.
Reassemble the thermostat housing and tighten it to the manufacturer’s torque specifications.

4. Check and Replace Radiator Fan

Tools Required: Multimeter, socket set
Disconnect the electrical connector to the radiator fan.
Test the fan motor with a multimeter for proper operation.
If the fan is faulty, remove it and replace it with a new fan assembly.

5. Refill Coolant and Bleed System

Refill the cooling system with the appropriate type of coolant (refer to the owner’s manual for specifications).
Bleed the cooling system to remove air pockets by running the engine with the radiator cap off until the thermostat opens and the coolant circulates.
