Oh I get where there coming from, the Sierra one closes at 86 degrees so this would bring your fans on earlier, the trouble is though as I say with these switchesthe 9 to 11 degree span these switches have, this is why the Sierra suffered with melted fuses etc due to the long period the fans are on for although I guess if others are doing it and haven't had problems they may be ok on the Escort.

It was due to the above reasons MSD introduced an uprated switch with a span of just a few degrees and also closing at a higher temperature around 92 degrees opposed to the 86 degrees of the Sierra hence bringing the fans on to early and then they either take ages to go off or stay on all the time.

I should think the first phase of the Escort is around the 92 degree area and so buying an uprated MSD switch woulden't help but a Sapphire one would,the Escos two stage setup was designed to keep the temps high for emission reasons.
