So last week my radiator decided to develop a crack in the top of the passenger side tank on the radiator. Had to disconnect an A/C line to get the radiator out losing all the freon in the system during the process. The LS A/C system takes 27oz of freon and they only sell cans, here at least, in 12oz size. They have bigger cans with stop leak and other conditioners, but I don't like to run anything but freon. So I put 2 cans in(24oz), but lost a couple ounces due to a bad o-ring on my gauges and it blows cold while driving, but not when at a stop. On top of all that, I was putting up my rear drivers' window and when it got to the top, CRACK, and my window started to fall. It I kept the window from falling far and put tape at the top of the window to hold it up. Anybody have any tips for holding the window up without tape?(besides buying the clips right now) Anybody use the clips off ebay? How hard/easy was the replacement job? Thanks for the help!!
