george87643 Posted October 16, 2022 Share Posted October 16, 2022 Hi all I have a Mondeo mk5 2015 140bhp just need some advice, after starting my engine the cooling fan comes on and stays on even if it's cold. I'm just not sure what this could be? or what to check to start ruling out. I'm hoping it's not the thermostat. Quote Link to comment Share on other sites More sharing options...
unofix Posted October 16, 2022 Share Posted October 16, 2022 Turn the Air Con off or at least set it to a warmer setting. 1 Quote Link to comment Share on other sites More sharing options...

TomsFocus Posted October 18, 2022 Share Posted October 18, 2022 Does the temp read ok on the gauge? If so, that should rule out the temp sensor and wiring to it. How long has it been happening? Might be trying to DPF regen. (In theory they should only start with a warm engine, but the mapping isn't perfect in my experience). Is the active grille shutter stuck closed? 1 Quote Link to comment Share on other sites More sharing options...
george87643 Posted October 18, 2022 Author Share Posted October 18, 2022 yeah, the temp reads fine, it happened about a month ago, I have looked around to find out what could be coursing it but can't seem to find anything. I don't think mine has the active grill shutter. 1 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted October 18, 2022 Share Posted October 18, 2022 Best advice I can offer is to have some Ford diagnostics plugged in next then. Forscan is ideal for DIY use. It's been covered many times on here so have a quick search if unsure. 2 Quote Link to comment Share on other sites More sharing options...
