Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Coolant Level Adjustment

If coolant is low:
- Open the coolant reservoir cap carefully.
- Add the recommended type of coolant to the appropriate level.

3. Leak Repair

If leaks are found:
- Replace faulty hoses or clamps.
- If the radiator or water pump is leaking, replace the component as necessary.

4. Thermostat Replacement

If the thermostat is faulty:
- Drain the coolant from the system.
- Remove the thermostat housing by unscrewing the bolts (use a socket set).
- Replace the old thermostat with a new one, ensuring the correct orientation.
- Reattach the thermostat housing and tighten to manufacturer’s torque specifications.
