... When I went to the dealer for the other service light, I had asked the guy about the coolant light. I was told the liquid may be hitting low but not low enough to add right now. But please paying attention to it & let him know....The coolant light lit up at the first acceleration after a complete stop. But after releasing the accel, the light turns off. The car runs great & no smokes or any type of leaks at this point.
When I got into a gas station, I had asked the guy to fill up the coolant as it seemed bit low anyway. So, the guy opened the cap & suddenly air shot out!!! After that, the coolant liquid came back & hit max. So he didn't add any coolant at that time.(perhaps pressure builds up?)
After a bit of pressure release, the light did not lit for a short while. But again, it started to lit as it used to.
As I can't figure out exact problem on this, perhaps some of the 96 850 owners may have better idea. I would appreciate some insights on this.
I am thinking it has something to do with the thermostat??? Perhaps it's time for a new one?
