Please settle an argument I've had recently. It was about whether the coolant level in the reservoir is also an indicator of the coolant level in the radiator. Not at any given time, of course, but -- say -- in mornings, before you start the car first time for the day. My position was that dropping coolant level in the reservoir under such conditions usually means the loss of coolant in the system requiring also checking the level under the radiator cap. However, with stable level in the reservoir I can open the radiator cap less often to check the coolant level there, too. My opponent said that I should check under the radiator cap just as often, even when the reservoir level is stable. What say you?
