- Summary
- Coolant warning light on or coolant loss. The left and/or right side radiator cooling fans may be inoperative due to corrosion caused by water ingress into the fan motors or into the fan control units. As a result, coolant temperatures may exceed the permissible value, leading to increased system pressure and potential coolant loss from the system. Indication of coolant loss may be noticed coming from the coolant reservoir.
