Firstly, the timing on your engine is retarded above 100 C, water temp, as much as 10%.
Secondly the viscous fan attached to water pump has a flex coupling that only locks up in air temperatures over 85F, when it locks up it takes 15 hp to run the fan.
Thirdly the auxiliary fans in front of the car only come on at 110 C water temp, (and when the a/c is on) by which time you could have lost 30-40 hp in losses.
I have a switch on my 500E that kicks the auxiliary fans in at 95 C.
I think your car has the same injection system so the switch should fit. It is completely automatic, completely hidden, costs about $25 and can be installed in a couple of minutes.
Also, get a pair of Spal electric fans, with an adjustable themostat, I'm sure two 13" will fit in your car, the car will run cooler and you will have more horsepower. I have a single 16" Spal fan, it works great
