jimjamyaha Posted November 22, 2017 Share Posted November 22, 2017 Hi All, Quick question that I've failed to find the information on a search of the forums or on the internet: What temperature does the official Ford thermostat rated to open on a 2.0l Petrol Duratec HE engine 145ps. Other third-party versions seems to be anything from 80C to 92C - confusing! Part number 1476110 Focus MK2 1.8/2.0 Petrol Thermostat & HousingFits 1.8 Duratec (125PS) Petrol EngineFits 2.0 Duratec (145PS) Petrol EngineFits From: 29-03-2004 To: 15-01-2008 Thanks.

JONATHAN_11_80 Posted November 23, 2017 Share Posted November 23, 2017 What the problem with the engine temperature? My 1.8 petrol warms up very quickly in the morning. Quote Link to comment Share on other sites More sharing options...

jimjamyaha Posted November 23, 2017 Author Share Posted November 23, 2017 Hi peeps, so the issue is that mine is stuck open and def needs replacing. However looking at the third party options the opening temps range between 80-98C... So wanting to know what the official ford version opens at, as assume the ECU will be programmed for a certain temp along with the matched radiator fan on temp. (Otherwise would get some confusing behaviour). Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted November 23, 2017 Share Posted November 23, 2017 99% sure it should be 89c on 1.8/2.0 petrol. 2 Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted November 23, 2017 Share Posted November 23, 2017 I'm with Tom on 89c I wouldn't go for 98, you'll be above operating temp before the rad opens. 80 and youll just be taking longer to warm up in the morning 2 Quote Link to comment Share on other sites More sharing options...
