On the Delphi / Cooligy model the hex ball end screws behind radiator have got to come out following the crossbar there are 2 10 T that are flathead with no washer note that because they have to go back same way. Do not forget the Power Buss for processor the powerleads have to be disconnected because processor board is under them. The Delphi / Cooligy has 2 pumps and was the least successful implementation of the LCS. Panasonic later made one which was great and sold as a replacement for the Delphi / Cooligy for a replacement (THE BEST IMPLMENTATION) of the LCS. Hope this help battling on of these beast myself.....
