So every once in a while you get a low coolant warning and you pop the hood. To your frustration you have to add coolant and you cant seem to find out why its disappearing. No drips and no smells…. so where can it be going?
In the picture below you can see the coolant is weeping out from he reinforcement threads inside the hose. It will look like mold coming out of the hose end. This will almost never drip on the ground and will evaporate not leaving a trail. The fix? New hoses because they are internally failed.
