pcassidy111 Posted February 20, 2006 Share Posted February 20, 2006 I am R&Ring the Hot side CAC tube to repair an oil leak on a 2005 PSD. The TSB states torque the HOT CAC clamps to 13 MN (115 inch pounds). Has anyone had the intercooler inlet crack when going this tight on the clamp at the intercooler? I am also tightening the cold side CAC clamps to 12Nm (as stated on the tube) but I cannot find a torque spec for the cold side CAC tube clamp at the intercooler outlet-is 12 Nm too tight? Can anyone give me the spec for the cold air CAC tube clamp at the intercooler? Also, is the white line on the silicone tube at the turbo (not the lines indicating clamp placement, the line perpendicular to those lines) supposed to be orientated straight up? On this truck it is not but the line on the tube at the intercooler is. Thanks, Pete Quote Link to comment Share on other sites More sharing options...
Jim Warman Posted February 21, 2006 Share Posted February 21, 2006 The torque spec sounds about right... there should be a metal insert inside the CAC nipple to help support the plastic. Once the engine is warm, I like to retorque. Cold side tubes should be in the same neighbourhood. Don't overtighten... this splits the boots. If you're concerned about reliability of the connection, make sure they are clean and dry.... where the silicon boots and the aluminum tubes meet, I spray Hi-Tack on tube and boot and let them sit for a few minutes. For the boot at the turbo.... I like to let it find where it wants to be without adding any stress input to it. The only thing I do pay attention to is that one end says "turbo".

pcassidy111 Posted February 21, 2006 Author Share Posted February 21, 2006 Thanks for the info Jim, figured I'd practice this repair on a customers truck before I do it on my own. /forums/images/%%GRAEMLIN_URL%%/smile.gif I did not notice the word'turbo' on the boot. One side of the boot had staples holding the clamp on it-I will look under the clamp tomorrow when I replace it (the threaded portion is bent). I am also replacing the clamp at the CAC (hot side) because the clamp appears to be streched-the ends of the clamp make contact at 90 inch pounds-the boot and CAC inlet look ok. Met some people visiting from Slave Lake area last week-laughed when I told them we are currently experiencing a major cold spell with a low of 37 degrees F at night. I guess it gets pretty cold where you are at. Quote Link to comment Share on other sites More sharing options...
