Checking the underhood space
Places to check for possible coolant leaks: 1 - expansion tank; 2 - thermostat; 3 - coolant temperature gauge sensor; 4 - radiator hoses; 5 - radiator drain plug; 6 - cylinder block drain plug; 7 - outlet hose for inlet pipe heating (under the fuel pump).
Recommendations:
- If leaks are detected at the hose connection points, tighten the clamps that secure them. Replace faulty clamps.
- If coolant is leaking through the plugs and sensors, tighten them.
- Inspect the hoses along their entire length, replace any that are torn, cracked or have lost elasticity. Before replacing the hoses, drain the fluid from the engine cooling system (see subsection 3.5).
