Coolant Blocked but no issue?
2005 Subaru Legacy GT Wagon Auto
Replaced this pipe on my car simply from what i thought was surface rust. It is a metal pipe that runs under the upper radiator hose connecting the coolant overflow reservoir and to the upper coolant reservoir (idk what its called) through a hose.
When i tested it in my sink it was and has been completed blocked for almost 9 months of ownership. Never overheated, has ran great, i am just wondering if theres something i should expect. After the test drive there was some new noises but otherwise did not seem anything was wrong.
