Question:

I have a 1992 gmc Sierra k1500 4 wheel drive and I’m wondering if all I need is this kit or do I need to but the adaptor to hook it up to my radiator. Not sure how I would go about figuring that out

The Insta-dapt radiator adapter is included with the Derale Dyno-Cool Tube-Fin Transmission Cooler Kit item # D12904. It fits vehicles with 5/16" transmission lines and enters the radiator with a threaded connector. If you do not want to remove the fitting from your radiator you will want to use the Derale Snap-In Radiator Adapter Fitting for GM item # D13035. I recommend purchasing the second adapter. I would be nervous and messing with a fitting that old.

This kit also includes an OEM rated hose and stainless steel clamps. I have linked a couple of installation videos below.
