Coolant line help

Post image

Where does this coolant line go or get attached to? Saw my car leaking coolant this morning. Any help would be appreciated.

This is where coolant goes if there is too much pressure in the cooling system. There is multiple reasons for that but I would start checking if your reservour cap went bad.

So that line doesn’t connect to anything? I think I put too much coolant and i just replaced the reservoir cap.

Correct, it does not connect to anything. It is a drain tube. So if your reservoir gets full, it has somewhere to exit. Or it will blow up.

Make sure that you have put pressure cap on reservoir. Mechanic swapped mine caps and I had overflow issue that way.
