1999 Monte Carlo 3.1 188k. (end user)
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.
