|DHD 007-5003 Duramax Trans Cooler & Radiator Fitting (7/8 Thread) To -10AN Outlet|
These stainless steel fittings are designed to help with aftermarket transmission cooler and line installations. These fittings will thread in to your Factory radiator transmission cooler and allow you to attach a -10 AN line to it. These fittings are a 7/8-14 to -10AN. This particular fitting is shorter in thread length than the bellhousing fitting. The concave tension washer is not included and must be reused of your old OE cooler fitting.
NOTE: This fitting will not fit some aftermarket OE replacement radiators due to a finer thread pitch. Use the picture below for reference. The course threaded fitting pictured below is what your radiator must have for these conversion fittings to work.
NOTE: Due to the thread height of this fitting you will need to reuse the factory tank washer. This will ensure the fitting tightens up correctly and the internal cooler is sealed against the coolant tank. See Below:
What the DHD fitting will look like when assembled correctly with OE washer.
