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 to prevent electrical shorts.

2. Coolant Level Adjustment

• Tools Required: Coolant funnel, distilled water or coolant mixture
• Remove the coolant reservoir cap.
• Add the appropriate coolant mixture to the reservoir up to the recommended level.
• Replace the cap securely.

3. Thermostat Replacement

• Tools Required: Socket set, torque wrench, gasket scraper
• Drain the coolant from the radiator into a clean container.
• Disconnect the upper and lower radiator hoses.
• Remove the thermostat housing bolts and lift off the housing.
• Replace the old thermostat with a new one, ensuring correct orientation.
• Clean the mating surfaces and install a new gasket.
• Reattach the thermostat housing and tighten bolts to the manufacturer’s torque specifications.

4. Water Pump Inspection/Replacement

• Tools Required: Socket set, coolant catch pan
• Drain the coolant from the system again.
• Remove components obstructing access to the water pump (e.g., belts, pulleys).
• Disconnect the hoses from the water pump.
• Remove the water pump mounting bolts and take out the pump.
• Install the new water pump, ensuring the gasket is in place.
• Reassemble all components and refill the cooling system with the correct coolant.

5. Radiator Cleaning/Replacement

• Tools Required: Hose, radiator cleaning solution (if necessary)
