Solution

1. Preparation

Gather tools: socket set, screwdriver, multimeter, coolant, and a thermometer.
Ensure the engine is cool and disconnect the battery to prevent electrical issues.

2. Check and Refill Coolant

Remove the radiator cap carefully.
Inspect the coolant level in the radiator and reservoir.
If low, top up with the manufacturer-recommended coolant mixture.

3. Replace the Thermostat (if faulty)

Locate the thermostat housing connected to the upper radiator hose.
Remove the housing bolts with a socket wrench.
Take out the old thermostat and replace it with a new one, ensuring correct orientation.
Reassemble the housing and tighten bolts to the manufacturer's torque specifications.

4. Inspect and Replace Water Pump (if malfunctioning)

Drain the coolant from the radiator.
Disconnect the hoses attached to the water pump.
Remove the water pump mounting bolts and take out the old pump.
Clean the mounting surface and install the new water pump, tightening the bolts to specified torque values.
Reconnect hoses and refill the cooling system with coolant.

5. Check for Radiator Blockages

Inspect the radiator for debris or blockages on the exterior.
If blocked, carefully clean with water or compressed air.
Consider flushing the radiator if internal blockages are suspected.
