Neat new part for front electric fan.
I've gone back to a clutch fan and though I have not been through a summer with the car I have had the temp up to 220F without the front clutch on and the electric fans never came on. No doubt with the clutch fan on when temps got high the coolant would have heat soaked the rad enough to engage the switches, but I wanted more protection.
Stumbled upon this little from bavauto part number 61 31 1 364 271. Its an 82C (180F) rad fan switch for two switch vehicles! So I've installed it for the low switch and then moved the high switch wires 99F to the OEM "low" switch at 91F. This makes sure that at 180F (which my clutch fan can maintain during lower ambient temps) the electric fan will come on low to assist.
