2007 Trailblazer LT
On the left side of the engine, sorta half way down, if you reach below the metal power steering lines and towards the front of the engine there is one maybe two rubber hoses or lines that you can easily move by hand. They're pretty much out of sight from above and below but can be seen if you know what you're looking for from under the truck. Any ideas what they are? Even a guess might be helpful. I got a leak of something in that area and below it and this hose is about as high as it goes. Wondering if this might be the source. I looked through some engine diagrams but came up with nothing...so...HELP?
