“I saw a blue liquid under my engine compartment. Should I worry about that?”

Yes, this is something you want to get checked out! One of the most common leaks found in cars is coolant (anti-freeze) leaks. These can be a blue color as you described.
When your car leaks coolant, there’s a high chance that your engine could overheat. If this is happens while driving, make sure to pull over and allow your engine to cool down.
There’s a few reasons why this is happening. The first is there could be a hole in your radiator caused by corrosion. This is normal. Tubes get worn out with age and will not seal properly.
Your radiator cap is also another part which can get worn out with time. It is supposed to seal tightly to create the right pressure for the cooling system. But with time this seal can weaken.
A more serious problem can be a blown head gasket. The head gasket is responsible for keeping engine oil and coolant separate, so when it fails to do so you can have leaks outside of the engine. This will result in your car being unable to cool down.
Driving around with a leak can lead to further problems and put you at risk of your car overheating on the road. We recommend bringing your car in for an inspection that will allow us to figure out and address the issue. To make an appointment call 360 Auto Clinic at (818) 369-6650. We are here to help you!
