    Default Info those who did my DTi intercooler mod...

    This is for those who did my intercoller mod/repair ( http://www.vectra-c.com/forum/showthread.php?t=116528 )

    It was -6c this morning. As I pulled away the car felt lumpy. About 2 miles down the road I pulled away from a set of lights and I went into limp home mode. Thought it was a little odd as I haven't had Limp Home Mode since I replaced my vacuum pipes. I switched off and then back on again. Pulled away and got Limp Home mode again! Thought it was little more serious than the vacuum pipes so pulled over and had a look at the hoses. My modified silicone intercooler hose had come of from the metal elbow. Luckily it was just a case of driving home in Limp-Home mode and getting my tools out. Lossend off the jubilee clip, put the metal elbow back into the silicone hose and did the jubilee clip REALLY tight.

    I think this happened for 3 reasons:

    1. The cold temperature (-6c) had made the metal elbow very cold and the metal and shrunk a little. Just enough to lossen itself form the jubilee clip.

    2. I had disabled the butterfly in the TB which made the engine judder when the engine switched off. This would have helped lossend the clip/elbow further.

    3. I hadn't tightened the clip up as much as I could? (although I thought it was on ****** tight and has been on there for a while). Maybe worth roughing up the outer part of the metal elbow where the silicone goes over it?

    It wasn't much fun faffing around under the bonnet in the cold and dark so thought I'd inform you of what I found so you can check that yours are secure.

    When i done my intercooler i changed all the piping to 2.5" ally pipe. At first the jubilee clips kept coming off so i changed them to t-bolts and have had no problems since. I suggest to get some of these rather than jubliee clips

    Can be a good idea to tighten the clips when the hoses are warmed up and softer.

    Used to have no end of problems with normal Jubbliee clips on my Astra turbo.

    Fitted proper Mikalor clamps (As they are designed for high clamping force and silicon hoses) and never had a problem after that.
