Hey guys, I am in the process of getting my coolant hoses replaced within the month but I've noticed that there's a crazy idle issue/squealing sound going on. Any ideas of what this is from? It happens before any coolant starts leaking from the hose.

 

Vacuum leak, not really related to any coolant issue. Very common on this engine, I just told another guy so here you go.

Hey guys, just an update on this but the idle issue / sound went away after replacing the coolant hoses... Not sure why if it's a fluke but drove it around and let her sit for a bit with no issues.
