Adrianlynch Posted May 15 Share Posted May 15 I have a 2016 1 litre ecoboost 123bhp fiesta. When driving I found hot air coming through the vents. ( the heat was not on) I pulled over to find the coolant boiling. I have brought it to a mechanic who changed the water pump and a thermostat and told me the issue was resolved. I drove the car to work the next day approximately a 45 minute commute. I opened the hood to find the coolant bubbling again. The temperature gauge in the car shows the car isn’t overheating. Any advice on this Quote Link to comment Share on other sites More sharing options...

Adrianlynch Posted May 15 Author Share Posted May 15 My mechanic says it’s not the head Apparently there is another water pump that circulates water from the turbo and that bubbling may be normal but I’ve never heard of that before 1 1 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted May 15 Share Posted May 15 Yes on the 1.0 EcoBoost there's an electric pump that keeps the coolant circulating after switch off. Initially only fitted to Focus's with a towbar, but then fitted to more, possibly all, later on. 1 Quote Link to comment Share on other sites More sharing options...
