My radiator got a leakage so I made a direct connection to the fan from the battery i.e. irrespective of the engine temperature the fan would start as soon as you turn on the ignition switch on. It worked fine in summers but in winters the gauge indication barely goes pass the "C" mark.
I think for engine to run smoothly there has to be a normal operating temperature which is usually indicated by the middle point of "C" and "H". I haven't observed it but I think the fan used to turn on when the needle would go past this middle point.
Should I be worried about this or is "the cooler the better"??
EDIT: thanks for the responses, but I meant the normal "operating temperature INDICATION". Because I cant measure the temperature. Is the operating temperature, people mentioned in the responses, indicated when the needle is exactly in the middle, a lil below that or where?
