I just did mine. Posted by B Millar [Email] (#1109) [Profile/Gallery] (more from B Millar) on Mon, 26 Oct 2009 12:34:03 In Reply to: Silicone hose replacements?.., RichF, Mon, 26 Oct 2009 10:55:40 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Just pull off the plastic "2.3t" engine cover and look for rubber vacuum lines that all look the same. The PCV and brake booster (if you have an auto) all use nylon/plastic tubes/hoses that do not need to be replaced. There's a rubber vacuum line coming off the throttle body that goes to a solenoid valve on the firewall. Then there are a few lines that split off of that. One goes to the turbo bypass valve up toward the front of the engine. Another goes to the intake manifold, and splits and goes to a fuel pressure something-or-other valve. Just replace all of these. I used a utility knife, needle-nosed pliers, and a flat head screw driver to cut the old hoses off. Be sure to do one at a time so you don't mix anything up. There are some larger hoses around the Boost Pressure Control (BPC) valve (front passenger side of the engine) that are already silicone so they do NOT need to be replaced. Good luck!
