- Yes it will often, its summers now. Hope you know there is a set temperature after which the fan will kick in. These days expect the fan to come in effect because it is actually HOT outside.
I have observed some posts of members having the radiator fan kicking in.
SUMMERS ARE HERE SO EXPECT LOT OF RADIATOR COOLING, ENSURE TO TOP UP COOLANT DURING YOUR PERIODIC SERVICE. IF YOU SEE A RED LIGHT ON THE CONSOLE WITH TEMPERATURE KINDLY HEAD TO SERVICE CENTER FOR COOLANT REFILL, ITS JUST A WARNING THAT ENGINE HEATING IS AT ITS PEAK AND THE COOLANT IN THE CHAMBER IS LESS.
The above is in caps so that everyone can glance with proper attention.
