I was looking at my car today and noticed that on top of the coolant reservoir there are 2 hoses coming off of it. One goes into the engine or wherever and the other is about 3 inched long and just hangs over the side of the reservoir. Then when I look down below the hose you can tell that coolant has ran down that side of the engine.

Is this normal. Aren't there are such things as coolant overflow, but I thought that it would go into another Reservoir not down the side of my engine.
Whats the deal?

 

It is the coolant over flow.. Some cars have an overflow reservoir some don't. it means you must manually check your coolant level. if you had and overflow as long as there was coolant in the res you would have enough.

 

Why does it overflow?

 

bad fingers should read

The coolant heats up. Pressure builds up. It needs a place to go. Does it do this often. Not really. But when it Does it is much better than your radiator exploding
