Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, coolant tester, multimeter, and safety goggles.
Ensure the engine is cool before starting any work to avoid burns.

2. Coolant System Inspection

Sub-step 1: Remove the engine cover (if applicable) using a socket set.
Sub-step 2: Inspect the coolant reservoir for cracks and ensure the cap is sealed tightly.
Sub-step 3: Check the coolant level; if low, top off with the manufacturer-recommended coolant mixture.

3. Thermostat Replacement (if faulty)

Sub-step 1: Disconnect the negative battery cable.
Sub-step 2: Drain the coolant from the radiator into a suitable container.
Sub-step 3: Locate the thermostat housing, remove the bolts using a socket set, and take out the old thermostat.
Sub-step 4: Clean the mating surfaces and install a new thermostat with a new gasket.
Sub-step 5: Reassemble the housing and refill the cooling system with coolant.

4. Cooling Fan Check and Repair

Sub-step 1: Inspect the fan wiring and connectors for damage.
Sub-step 2: Using a multimeter, check for voltage at the fan connector when the engine reaches operating temperature.
Sub-step 3: If the fan does not operate, replace it with a new unit according to the manufacturer specifications.

5. Water Pump Inspection

Sub-step 1: Check for leaks around the water pump area.
Sub-step 2: If signs of failure are present, remove the old water pump by disconnecting hoses and unbolting it from the engine.
Sub-step 3: Install the new water pump and ensure all connections are secure before refilling the coolant.
