I started my 99 Taurus this morning and the engine was running well as
usual. But the engine stopped unexpectedly when I changed from Park
position to Reverse. I could easily start the car again at Park, but the
engine stopped as soon as I changed it into Reverse for many times. Then I
ran the engine at Park and waited until the temperature reached its normal
value (~1/3 on the scale). Then the car seems to recover. However, I drived
only a few miles on local road and found the temperature had rised up to 2/3
position (it never reached beyond 1/2, and normally at about 1/3). I then
drived slowly back to home (although the temperature seemed to go back to
1/3). I checked and only found the coolant was boiling out through the cap
on the reservoir.
Could it be possible the coolant was iced and broke channel on the engine
(the coolant is mostly water nad it was around 0 degree last night)? Welcome
any suggestion ... Thank you very much!
