For a while now, when I have been driving, park in my garage and turn off the engine, if I wait a few seconds, there is a bubbling sound coming from under the bonnet.
Obviously this has something to do with the cooling system but the engine's not overheating and the noise has been happening for months now so it's probably nothing to worry about.
However, I would still like to know if this is something to be concerned about. It sounds as though there is water bubbling back into the rad. Could there possibly be some kind of blockage?
