I replaced my radiator on my 04 LX470 this past weekend. I've been driving around all week with distilled water in the coolant system to clean out the crud. Now it's time to flush out the coolant system, fill up with some red, and wrap this project up. However, I cannot access the coolant drain on the PS engine block. I can easily get the tubing on the drain, and a socket on the drain bolt, but I can't get a wrench up there. Someone has to have a trick or a solution to easily access the coolant drain plug. If you do can you share it please?
