How to Install our ACCIII Climate Control Performance Upgrade - On Demand Video

This applies to the 1981 to 1985 W123 and the 1982 to 1989 R107. Also indirectly to the W126

This an instructional "how-to" video that comes with our ACCIII performance upgrade it. It will show you how to install a protective fuse for your auxillary water pump and how to replace the rotton foam climate control hose under your dash. Total run time is 16:29. The video was filmed using a W123 300D turbo and a R107 380SL. The principles apply to the early W126 but you won't see the actual process for that model. Also for the late W126 with the temp sensor overhead you will not need to remove the glove box. Nor will you need the black hose.
