Why does my engine coolant completely get used?
Why does my engine coolant get sucked up and then released back into the
reservoir on my 2005 Cadillac Deville?
I will fill up the coolant reservoir to the fill line. I cut my car on and after about
30 minutes it will suck up ALL the coolant. When I twist the cap to the
reservoir then the coolant all comes back. This does not always happen.
Sometimes the coolant, all gets used up and twisting the cap does not bring
it back.
