Does anyone with a Kia Spectra have a problem with coolant swishing around behind the dashboard? Has anyone discovered a permanent repair for this? After having the coolant purged of air, it is quiet for, at best, 2 months. Anyone else dealt with this issue? Thanks in advance.
If purging the cooling system of air gets rid of the swishing noise and then it returns, then there must be a coolant leak somewhere.
Although we have different cars, with my car (which is known for head gasket failures), this was one of the symptoms of a head gasket leak allowing exhaust gases to get into the coolant.
