Goalie30 Posted December 5, 2012 Share Posted December 5, 2012 Have a 2007 Exlporer Limited. Wife drives it and has been noticing that the warning lights on the dash will come on indicating an engine overheating. Did this like twice last winter when it was like -15 degrees out and has did not happen all summer. Now with the weather getting cold again it is acting up again. Warning lights come on like it is overheating. Stop. shut the truck off and it is fine again. We have noticed that warm air will only be generated and blow out of the vents when the truck is moving. When in park - only cold air blows out. Thinking that the thermostat is sticking or fried. Any other ideas? Quote Link to comment Share on other sites More sharing options...
YT90SC Posted December 6, 2012 Share Posted December 6, 2012 full of coolant in the radiator, not just the overflow? these are terrible about leaks in the rad and in th t-stat housing. Quote Link to comment Share on other sites More sharing options...
Goalie30 Posted December 6, 2012 Author Share Posted December 6, 2012 I haev not seen any leakage. Though I have notice that you can hear liquid gurgling when you start it after sitting for a while - over night. I will double check the coolant.

YT90SC Posted December 7, 2012 Share Posted December 7, 2012 leakage will be small, but it will look like dried crusty chalk where it has leaked. Check the t-stat housing area, and the upper radiator tank to core seal area. the rad will be harder to see. Quote Link to comment Share on other sites More sharing options...
