I need to replace this hose and wanted to know if anyone knows what system its attached to so I can ask the dealer.

I appreciate it

That is a coolant hose. If you look at it close you can see that it comes from the radiator.

Probably a coolant hose, but not to the radiator (that one is a much larger diameter hose to the front of the one indicated by the OP), and may go to the heater core inside the car.

Check the plumbing diagrams at RealOEM.com.

Don't spread incorrect information if you don't know what you're talking about.

No.


Both of these people are wrong. It's the vacuum line for the brake booster.

Actually, I did know what he was talking about. The problem was that I thought he was referencing the large hose, not the small one. The large one does contain coolant, but you are correct that the small one is vacuum line.

No worries
