Striplin Subject: [MBZ] ML AC I put the AC back together last weekend but had a massive leak would not hold vacuum. I figured I had the wrong size o rings installed so I ordered the kit, which I went and replaced all the o rings again today, which included the expansion valve, drier, and compressor. I still had a leak so I put a lb of R134 in to check for leaks. Its coming from the expansion valve area. I sucked out the 134 and removed the valve again. There is a piece that fits behind the lines coming out of the evap that 2 bolts screw into that hold the valve to the evap. The top one appears to be stripped out at it never tightened down. The bottom one does but maybe its not holding it tight enough. I am hoping that piece is removable and replaceable or I can repair it. I am going to check the epc now. What a hassle. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
