Had a reasonable summer here is Oz but noticing that the car runs a bit hotter than I would like. In traffic quite common to get to 110degC consistently. My thermofans are not kicking in till 110 and then keep the temp well but I would like to get it back down to 95degC.

Does anyone know how or if you can adjust the temp where the thermo fans start and stop.

Regards

I may not be totally up to speed but I think they should kick in at 82 degrees.
Kind regards,
Ed
P.S.just checked the tech manual - 82 degrees it is - that is the thermostat temp. I suspect that is not an adjustable item so replacing that or the thermocouple that measures the coolant temp may sort the problem...as I say...I am not totally up to speed on the systems, sorry

You did not say what year of Esprit you have, but on my '89 non-SE the fans are controlled by a small thermistor located in the thermostat housing( when you take it out you can see its set point temperature, 92-93C) at the front of the engine, left side(front meaning just behind the firewall). But, the fans on mine were also coming on as soon as I would turn on the key and no A/C on. This was being caused by the ECM (as part of the A/C control circuit) which two years later had to be replaced.

As I posted before, some relief of heat build up in the engine bay, basically an engine-in-a-box, can be had by cutting out (allowing about 1/2 inch edge of the low point of the pan)some of the blanked out portions of the bottom pan and installing galvanized or stainless steel shop cloth in the holes. This is like the McLaren F1(also a Stevens design) is set up. Here in Louisiana I have not had to change my red hose. I have also found that along with synthetic gear oil, I use Valvoline, putting in some Prolong keeps the temperature down.

And ,of course, I cleaned my cooling system.

Hope this helps,
Bob Kumse'89 non-SE
