82c Thermostat Fan settings

[VK_3800]

I still run the original 82 degree thermostat (factory fitted to early 308s) with a pair of electric fans on a single circuit which switch on at 95 (off at 90). The original temp gauge on the dash still shows a similar range to before, the fans don't run too often or too long and the temp rarely creeps above the 95 which gives me at least 10-15 degrees safety margin.

Yeah, I get that bit, it's just that heat soak is a bitch.

since when does the factory care about that ?

True, all they care about is getting the best possible economy numbers, never mind how the car will run after it runs out of it's warranty.......

Thanks to all, have made changes and will test it out.

That's what it's all about, trial and error

im about to run twin themo's on a little 253, 92c on 87c off, with an 82c themostat, hopefully its right

i found most read 80 - 82c while on the highway and in winter may drop 1c more, mine reads 79c in winter and 80c in summer, i use that stable reading to base fan settings on with a 2c margin, ive found 4c difference between on and off to be good without the fans getting annoying. i also use the high speed fans with a 2c difference from low so if the temp climbs a bit it comes on to help drop it back in low fan range. So if it was 80c i would use these. I find the factory settings to wide i like to keep my engine at a nice stable temp.

Low
86 on
82 off

High
88 on
84 off

Everything is working well, maybe some slight tweaking like The1 has mentioned ^^^.

Thanks
