I have a Ford connect 2014 having issues with my coolant system seems to lose water every two days but when it comes to filling up on cold opening the cap it pushes pressure and making coolant rise to the top to max line There is no issues of oil mixing with water it did have a airlock but had been removed

Hey Fordy1-7,

 

Was just going to post a general "Hello" in this lounge when I noticed your topic.  I just now posted the following in the 2015 Forum:

 

So my trusty 2015 2.5 L Connect XLT had a little temperature tantrum. I routinely do most of my own maintenance oil, fluids filters etc. Low miles on her 60,023.  About a pint of antifreeze used since my coolant system flush at 30,000. 

On a short errand yesterday, 12 miles total travel, 70' ambient temperature  she went in to "Limp mode" with a temperature warning. Luckily I was only about 1 1/2 mile from my home when it occurred. No visible leakage to the ground just steam and hissing coming from what may have been the waterpump seal vent if it has one? After dinner in my driveway I topped off the resevoi, started 'er up and as the thermostat opened I was able to continue refilling the system.  No leakage or steam as temperature came to midway on the gage. Back and forth to work about three city miles each way no tantrums, no leakage.
 
With never using the heater for about nine months (Florida) and finally using it last week, could some debris have  dislodged from the heater core? Holding the thermostat open or causing some sensor to hold the system in the COLD mode? Any ideas, suggestions, similar experiences?

I will keep ya's posted. Oh by the way, I previously queried here about errantly using about a gallon or so of VP110 leaded race fuel in my van about 6,000 miles ago. Did not seem to mind a bit. Never even smelled that awful sulfur     "Aroma".

Keep wrench'n
