Cygnus Posted October 17, 2010 Report Share Posted October 17, 2010 (edited) Ok, I was filling up some wiper fluid and I notice this plastic tube broken off at the end. It leads back to this joint which located next to the master cylinder and strut tower. What is it and where does the other end that is broken off go to? Edited October 17, 2010 by Cygnus Oops, forgot the question. :P Quote Link to comment Share on other sites More sharing options...

Cygnus Posted October 17, 2010 Author Report Share Posted October 17, 2010 Ok, what is it for and where does it connect to? Quote Link to comment Share on other sites More sharing options...
gpchris Posted October 17, 2010 Report Share Posted October 17, 2010 im pretty sure that goes from the intake manifold to the hvac system and the vacuum tank in the fender. The hvac system requires vacuum so when the engines off the tank stores a little vacuum so the hvac controls can be operated for a short amount of time when the engines not running.
