samuelegooding87 Posted December 5, 2012 Report Share Posted December 5, 2012 I have a 2010 SHO PP and when at idle the car blows cold air. When I accelerate or maintain RPMs above 1800 it starts blowing heat again. Very annoying, any Ideas? Quote Link to comment Share on other sites More sharing options...
steve142857 Posted December 5, 2012 Report Share Posted December 5, 2012 Have you checked if you have enough prestone? Quote Link to comment Share on other sites More sharing options...
Scrming Posted December 5, 2012 Report Share Posted December 5, 2012 I vaguely remember there being a TSB for that... sorry, i don't have more info handy... Quote Link to comment Share on other sites More sharing options...
JoeB Posted December 6, 2012 Report Share Posted December 6, 2012 I'm having the exact same problem. Pushing the button to circulate inside the car sort of helps sometimes but barely. I hope someone can help, it's getting cold out lol. Quote Link to comment Share on other sites More sharing options...
SteelBlue402A Posted December 18, 2012 Report Share Posted December 18, 2012 I just had mine in for the same thing they removed the radiator cap and let the car warm up and revved the car at about 3000 rpm for a couple minutes, said it had developed an air bubble so they burped it. there is a tsb out for this but I do not know the number. You should see a slight decrease in the amount of coolant in the radiator tank if you do it right.Mine works great now Quote Link to comment Share on other sites More sharing options...
Carson Lomax Posted December 29, 2012 Report Share Posted December 29, 2012 Mine is also doing this. It's a 2010 (Oct '09 build) and I haven't done anything to the car. How can these just "mysteriously" develop air bubbles? The overflow tank is full and I've tried burping the system myself but I didn't get anything out of it. My dealer wants me to bring it by versus looking up the TSB for me but I'm not inclined to pay for the trip to the shop if I can fix it myself.

SteelBlue402A Posted December 29, 2012 Report Share Posted December 29, 2012 I will stop and talk to my buddy that is the mechanic who checked mine and see if he can get me the details of what he did, and or tsb number Quote Link to comment Share on other sites More sharing options...
carmanone@rocketmail.com Posted January 1, 2013 Report Share Posted January 1, 2013 same problem, dealer replaced thermostat and "burped" the cooling system. it seems slightly better however heat does diminish at idle, bring the rpms up slightly and you get proper heat. would really like to know the TSB if anyone out there has it or if one does exist.

kws6000 Posted January 6, 2013 Report Share Posted January 6, 2013 My 2012 Turbo Brick was doing the same thing. There is a tsb for the Ford flex/Lincoln mkt .... #12-4-2 for this problem...I just had this done,however the weather hasnt been cold enough to see what effect the repair has had.

swetrid Posted January 6, 2013 Report Share Posted January 6, 2013 I had this tsb done but it is still noticeable at times when car is at idle. Quote Link to comment Share on other sites More sharing options...
Guest K4u2luz2 Posted January 7, 2013 Report Share Posted January 7, 2013 I just noticed this in mine as well. Totally unacceptable and I will be taking it in next week. Ford better have a solution I have no plans to be cold when sitting in traffic during my two hour daily commute. Quote Link to comment Share on other sites More sharing options...
Slowsho Posted January 7, 2013 Report Share Posted January 7, 2013 Mine did this acouple weeks ago. I thought I was going crazy. It hasn't done it since then. Quote Link to comment Share on other sites More sharing options...
mval Posted January 7, 2013 Report Share Posted January 7, 2013 I've had trouble w/my '10 SHO 2 years in a row, where passenger side feeds only cold air while drivers side sends some heat. I was told it's a blending door that it's not working right. It's fixed for now but troublesome. Quote Link to comment Share on other sites More sharing options...
DJNSHO1 Posted February 1, 2013 Report Share Posted February 1, 2013 Mine has also done the no heat at idle a few times when it has been extremely cold out, I have also noticed a running liquid sound from behind the dash on start cold mornings when first starting the car.

gpfarrell Posted February 2, 2013 Report Share Posted February 2, 2013 I have warm heat at low engine speeds, but it's not hot until the revs get kicked up. Quote Link to comment Share on other sites More sharing options...
SteelBlue402A Posted February 2, 2013 Report Share Posted February 2, 2013 Guys, my past experience has always been that "running water noise" is the coolant running into the heater core. It is somewhat normal(meaning you may sometimes hear it especially when changing from cool to heat) but will be more pronounced when coolant is low.The tech at ford told me mine was just a little low and had gotten air in the system, and he took the cap off and let it run until the thermostat opened up. Once the coolant started circulating he slowly raised the rpm to 2,000+ for a minute or so. Keep doing it until you don't see the tiny air bubbles in the tank anymore. Then check the coolant level, add some if necessary. Quote Link to comment Share on other sites More sharing options...
