Should my reservoir be between MAX and MIN when engine is cold even though I had it at the full mark? I've been using the heater recently since the temperature drop.

This used to happen on my mom's Camry but no overheating and I kinda see it on my TL but still no overheating either.. Whiich leaves me wondering if my radiator cap is going.

I topped off the radiator and the reservoir and checked for leaks since i recently changed my radiator. and everything is fine... I'm just puzzled why it is not a MAX all the time when cold.

Does using the hear cause this? I'm 100% sure I don't have a leak...

 

Normal operating.. coolant gets pulled into the radiator.

 

It should be between the min and max at all times. Close to the min when cold and close to the max when hot.

 

Thanks.... Just checked it since coming off the road and it's working like dopeboy1 said.
