Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting repairs to avoid burns.
Disconnect the battery to prevent electrical issues.

2. Replace Coolant

Drain the existing coolant from the radiator using a drain pan.
Remove the radiator cap and allow the system to drain completely.
Refill with a 50/50 mixture of approved coolant and distilled water.

3. Inspect and Replace Thermostat

Locate the thermostat housing and remove the bolts using a socket set.
Carefully lift the thermostat out, checking for wear or damage.
Install a new thermostat, ensuring it is oriented correctly, and torque the bolts to the manufacturer’s specification (typically around 15-20 Nm).

4. Inspect and Replace Water Pump (if necessary)

Remove any components obstructing access to the water pump (e.g., serpentine belt).
Unbolt the water pump from the engine block and remove it.
Clean the mounting surface on the engine and install a new water pump, ensuring the gasket is properly seated.
Torque the water pump bolts to the specified value (usually around 10-12 Nm).

5. Check Radiator and Hoses

Inspect the radiator for blockages or damage. Clean if necessary, or replace if damaged.
Examine all hoses for cracks or leaks and replace any faulty hoses.

6. Reconnect Components

Reattach any components removed for access.
Reconnect the battery.
