Lets face it, the coolant filling system found on the LT4 supercharged C7 Corvette, Camaro ZL1 and CTS-V can be a real pain in the butt to fill. Over the years we've tried a number of different solutions but none of them did the job without some pitfalls. DMS recently designed an adapter that installs on the filler fitting while depressing the check valve allowing the use of a very common soda or water bottle to act as a "funnel". The threads are the same as many drink bottles like Coke, Dr. Pepper, Mountain Dew, Smart Water and many more. This makes the tool small and easy to keep in the car for those unexpected cooling system filling needs.
Includes one of each tool to cover all ranges of LT4 cooling systems.
