Had our Granddaughter hold the hood up,to remove the battery.Got the battery out,but had to remove the hood to figure out how to removethe screws from the base of the heater box. John,a Master Mechanic,came over,& helped me figure out how to remove the screws,without resorting to destroying them. Pulled the heater box out (By the way,only the back part comes offeasily - 2/3rd - 1third).Now I need to paint/re-install. "Reassembling is the reverse of disassembly"........... - Doug
