Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting work.
Disconnect the battery to ensure safety.

2. Coolant Level and Condition

Remove the radiator cap (only when engine is cool).
Inspect coolant level; if low, top off with the manufacturer-recommended coolant type.
Check for signs of contamination (oil or debris) in the coolant.

3. Thermostat Replacement (if faulty)

Tools Required: Socket set, screwdriver, gasket scraper
Locate the thermostat housing.
Remove the bolts securing the thermostat housing and carefully lift the housing off.
Remove the old thermostat and gasket.
Install the new thermostat with the correct orientation and a new gasket.
Reattach the thermostat housing and torque the bolts to the manufacturer’s specifications.

4. Radiator and Hose Inspection

Inspect the radiator for physical damage or blockages.
Check all hoses for cracks, bulges, or leaks.
Replace any damaged hoses with new ones.

5. Water Pump Replacement (if defective)

Drain the coolant from the system.
Disconnect the hoses from the water pump.
Remove the water pump mounting bolts and carefully take out the pump.
Clean the mounting surface and install the new water pump with a new gasket.
Reconnect hoses and refill the cooling system with coolant.

6. Cooling Fan and Electrical Check

Inspect the cooling fan for debris or damage.
Test the fan operation by connecting it directly to the battery (if applicable).
Check electrical connections and fuses related to the cooling fan circuit.
