So, the coolant appears to stay warmer for much longer than normal and also seems to heat to operating temperature much quicker. Should I be concerned ? The car isn't overheating and drives normally. I've checked thoroughly for coolant leaks and found none. It is also not losing coolant. I suspect the cooling fan relay may be broken or perhaps the coolant needs to be flushed. Can anyone shed some light on this ? Thanks.
Ps. There are no warning lights and it warms to operating temperature in about 6km of easy driving. This would normally be closer to 9 or 10km.
