Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Replace Coolant

Tools Required: Radiator wrench, funnel, container for old coolant.
Drain the old coolant from the radiator by opening the drain valve at the bottom of the radiator.
Close the drain valve and fill the radiator with a 50/50 mixture of manufacturer-recommended coolant and distilled water using a funnel.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, gasket scraper, new thermostat, and gasket.
Locate the thermostat housing and remove the bolts securing it.
Carefully lift the housing off, removing the old thermostat and gasket.
Clean the mating surfaces to ensure a good seal.
Install the new thermostat with the correct orientation and a new gasket, then reattach the housing and torque the bolts to the manufacturer’s specifications.

4. Inspect and Replace Water Pump (if necessary)

Tools Required: Socket set, screwdriver, new water pump, gasket or sealant.
Remove any components obstructing access to the water pump (e.g., serpentine belt, timing cover).
Disconnect the hoses attached to the water pump and unbolt it from the engine.
Install the new water pump with a new gasket, ensuring proper alignment, and torque the bolts to specifications.

5. Test the Cooling System

Refill the coolant system and bleed any air out by running the engine with the radiator cap off until the thermostat opens and air bubbles escape.
Replace the radiator cap and monitor the system for leaks.
