A cooling system for an engine disposed within an engine room, the cooling system comprising: a first cooling circuit comprising: a first heat exchanger configured to receive cooling fluid; and a first cooling conduit disposed in fluid communication with the first heat exchanger, the first cooling conduit configured to transport the cooling fluid to an intercooler associated with the engine; a second cooling circuit comprising: a second heat exchanger configured to receive cooling fluid; and a second cooling conduit disposed in fluid communication with the second heat exchanger, the second cooling conduit configured to transport cooling fluid to a cooling jacket associated with the engine; a fan configured to draw air over the first heat exchanger, through the engine room, and over the second heat exchanger; a first connecting conduit fluidly connecting the first cooling conduit and the second cooling conduit; a diverter valve disposed in the first connecting conduit, the diverter valve configured to control flow of cooling fluid from the second cooling conduit to the first cooling conduit; and a controller communicably coupled to the diverter valve, the controller configured to regulate the diverter valve to allow flow of cooling fluid from the second cooling conduit to the first cooling conduit based on at least one of air temperature in the engine room and ambient air temperature so as to regulate temperature of air within the engine room. a first cooling circuit comprising: a first heat exchanger configured to receive cooling fluid; and a first cooling conduit disposed in fluid communication with the first heat exchanger, the first cooling conduit configured to transport the cooling fluid to an intercooler associated with the engine; a first heat exchanger configured to receive cooling fluid; and a first cooling conduit disposed in fluid communication with the first heat exchanger, the first cooling conduit configured to transport the cooling fluid to an intercooler associated with the engine; a second cooling circuit comprising: a second heat exchanger configured to receive cooling fluid; and a second cooling conduit disposed in fluid communication with the second heat exchanger, the second cooling conduit configured to transport cooling fluid to a cooling jacket associated with the engine; a second heat exchanger configured to receive cooling fluid; and a second cooling conduit disposed in fluid communication with the second heat exchanger, the second cooling conduit configured to transport cooling fluid to a cooling jacket associated with the engine; a fan configured to draw air over the first heat exchanger, through the engine room, and over the second heat exchanger; a first connecting conduit fluidly connecting the first cooling conduit and the second cooling conduit; a diverter valve disposed in the first connecting conduit, the diverter valve configured to control flow of cooling fluid from the second cooling conduit to the first cooling conduit; and a controller communicably coupled to the diverter valve, the controller configured to regulate the diverter valve to allow flow of cooling fluid from the second cooling conduit to the first cooling conduit based on at least one of air temperature in the engine room and ambient air temperature so as to regulate temperature of air within the engine room.
