Kudos To Mercedes For Rejecting the Kullman Koolant!
Special thanks to the executives and engineers of Mercedes-Benz for refusing to accept blindly the hollow words and questionable lab tests of DuPont Management and their servile engineers. Instead you chose to put the Kullman Koolant, DuPont/Honeywell's "Sustainability"-touted HFO-1234fy through rigourous real-life testing.
After intensive independent testing, you were shocked to discover that in a real-life collision, the Kullman Koolant can burst into lethal toxic flames once a refrigerant line is fractured and Kullman Koolant hits a hot engine part.
In short, the management and engineers of Mercedes in renouncing the Kullman Koolant as a serious SAFETY danger are protecting their fine car customers and their families, and concomitantly Daimler shareholders.
