Coolant Alarm "WINTER BEEP"
Posted: Sat Oct 23, 2010 10:43 am
As the weather gets colder we get the same obsevation every winter......My coolant alarm has a much longer "test" beep and "mutters" a bit until we get going.
The alarm depends on the coolant to conduct the small electric current from the Tank probe/screw to earth....Coolant is quite a good conductor when warm (above 20C) below this temperture it gradually becoms much less able to conduct and at temps of 5C and below very poor indeed.....
So...if your alarm "mutters" untill the coolant warms up a bit ...this is perfectly normal and nothing to worry about....
Of course if this persists even when warm.....investigate and check your levels.
