Step-by-Step Inspection Process
1. Check Coolant Level
Start by checking the coolant level in the reservoir tank. Make sure the engine is cool before opening the cap to avoid burns.
- Locate the reservoir tank.
- Check the marked levels on the tank.
- If low, add the appropriate coolant mixture.
2. Inspect Hoses and Connections
Examine the coolant hoses for any signs of wear, cracks, or leaks. Ensure that all connections are tight and secure.
- Look for any visible leaks.
- Check for soft or bulging hoses.
