coolant light on, car hot, temp gauge normal

[my first 420a]

okay so first of all my engine bay get really hot doesnt seem normal to me but ill leave that up to the people who know their stuff. so my coolant light comes on every couple days sometimes daily the first time it came on i filled the resevoir tank and the next day it was bone dry so i took the radiator cap off and it was low in there so i filled that ive been filling the it up from the radiator cap for awhile now and it always seems to come on and when i open it up its low. so here is what i was told about the coolant problem that it could have a air bubble in the system and it just doesnt have enough coolant. so idk what to do about that also the stock radiator has two fans i only have one because of my fmic piping so could this be a reason why engine bay gets so hot but temp light is okay. also maybe a bad radiator. and i was told that if you have AC that you need two fans and one just wont keep it cool. well thanks for reading this hopefully someone will help me out. give me your ideas.

it might be a leaky water pump or turbo coolant line i'd check them both. good luck if it's the water pump
