Depending on how hot your engine gets, how hot it is out side and the +/- of your particular TTS switch. In Arizona during the summer it may never cool down below 95F. John Hervey -----Original Message----- From:bitsyncmater Subject: [DML] Re: Warm Start Issue (David McKeen) So should my engine have cooled in the 90 degree summer heat after 3 hours? If not than the cold start injector has nothing to do with starting it then. How long does it take for the engine to cool for the thermal switch to switch on?
