My S2 111S fan comes on at about 101-102 deg, and you cant normally hear it. You will probable see heat haze rising from the front of the car when the fan starts, but as long as the temp doesnt rise above about 105 deg, I wouldn't be too bothered (the fan normally reduces the temperature quite quickly once it comes on).
Mike...
Mike...
Just to echo what's been said... My S2 111S gets to about 102 (or thereabouts) then the fan cuts in - though I haven't heard it, the temp starts to drop a little, more quickly with just the very slightest of forward motion (even stop start traffic type motion). It is a relief when it happens and a bit disconcerting first time round.
HTH, Andrew.

My fan is supposed to come in at 102, but apparently doesn't. Sitting in glorious sunshine in long queue of traffic and the temperature started to rise.....and rise.
Got to 116C and decided enough was enough and pulled over and popped the boot and let it sit for 30 mins.
According to the manual, the coolant system is rated to 120C so hopefully it's OK. But incidentally, aside from emulsion in the oil, anyway you can tell if you have HG problems?? Any common symptoms? There is evidence of some dried material on the outside of the coolant reservoir but not much else I can see.
Cheers.

Yup, same here

I have also noticed dried coolant on the outside of the reservoir during this very hot weather. Is it just some of the coolant sneaking its way out of the cap at very high pressure? Is this something to be concerned about??

Other thing that can happen if temp gets too much is that the crappy crimping on the radiator will give way causing a radiator leak.
Cheery on here isnt it
Its also not that convenient to sit around for half an hour every time you go out to check if the fans gonna come in.

When mine hits 102 I usually turn the blowers off and the radio, dim the console lights, anything really that usaully takes it down to at least 96 
When mine gets to 102 I've been turning the heat up and the blowers on... this used to work in my Turbo Diesel Astra (
don't laugh) my reason for this was to try and get the heat away from the engine by sucking it into the car (yes... I also had to open all the windows) but this definitely worked I did wonder if I was doing the right thing by doing this in the Lotus, what with the engine being in the back and me not knowing where the heater sucks the warm air from, front or back?
Sorry if I'm being a thicky but I am a girl afterall and therefore don't inherit the technical gene, which normally seems to pass down the paternal line.
So what should I do? Turn the heaters on or off?

your logic is fine - turn the heater up to full and turn the fan on.
The heater doesn't suck warm air from anywhere, it heats up the air using the engine coolant through a small heat exchanger (a radiator)- so turning the heat up will help to cool the engine.
