Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before beginning work.
Safety gear (gloves and goggles) should be worn.

2. Check and Refill Coolant

Locate the coolant reservoir and remove the cap.
If the coolant is low, top it up with a 50/50 mix of coolant and distilled water.
Check for proper coolant type as specified in the owner's manual.

3. Inspect and Replace Thermostat

Tools Required: Socket set, torque wrench.
Remove the thermostat housing bolts using a socket wrench.
Carefully lift the thermostat out of the housing and inspect it.
If it does not open or is stuck, replace it with a new one.
Reinstall the housing and torque the bolts to manufacturer specifications.

4. Check Radiator and Hoses

Inspect the radiator for any external debris or blockages.
If clogged, clean the radiator fins with compressed air or a soft brush.
Examine hoses for cracks or bulges; replace any damaged hoses.

5. Test and Repair Cooling Fans

Start the engine and check if the cooling fans engage when the temperature rises.
If they do not operate, check the fan relay and fuse.
Replace the cooling fan motor if it is found to be faulty.
