Solution

1. Preparation

Gather required tools and parts.
Ensure the engine is cool and disconnect the negative battery cable for safety.

2. Coolant Level Check and Refill

Open the hood and locate the coolant reservoir.
If the coolant is low, refill it with a 50/50 mixture of antifreeze and distilled water.

3. Inspect and Replace Thermostat

Tools Required: Socket set, screwdriver, gasket scraper
Remove the thermostat housing bolts using a socket.
Take out the old thermostat and inspect for proper opening.
Clean the mating surface on the engine.
Install the new thermostat with a new gasket, ensuring it is oriented correctly.
Torque the housing bolts to the manufacturer’s specification (typically 15-20 ft-lbs).

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, wrench set, coolant catch pan
Drain the coolant from the radiator into a catch pan.
Remove the serpentine belt from the water pump by loosening the tensioner.
Unbolt the water pump from the engine and remove it.
Clean the mounting surface and install the new water pump using a new gasket.
Torque the bolts to the manufacturer's specification.

5. Check and Repair Leaks

Inspect all hoses and connections for visible leaks.
Replace any damaged hoses or clamps as necessary.
Ensure the radiator is free from debris and obstructions.

6. Test Radiator Fan Operation

Start the engine and monitor the radiator fan.
If the fan does not engage as the temperature rises, test the fan relay and replace if faulty.
