Had the EGR head gasket problem fixed around 100k. High use day to day.
The other day noticed the low coolant light on in the am going to work. Came back home and filled her up (overflow).
Took her easy on the way to work going thru numerous heat up cool down cycles. Still on at lunch. Cracked open radiator and it was full. Resevore is full and I can drive the car all over town and the temp gauge work fine and car operates at normal temps. Top hose is under pressure and filled with coolant. But the light continues to stay on. Sometimes it blinks and other times it is steady.
Does this sound like trapped air and the bleeder valve need to be opened?
Thanks in advance.
