Funny this! Today I went over to the coach to see if my genset coolant leak was a lose cap or bad connection to the cap area, which is under this little plate mentioned above. On my plate, it clearly states, coolant cap and DC fuses are located under this plate. Never noticed the little notice before, but knew the cap was under this plate. Leak was not there, guess the top sheet metal is coming off maybe tomorrow to find it. Hope I don't have to take it to cummins as last year they fixed a hose which had leaked down below on the bottom of the unit, took them a week to get the hose.
