Hi all.. Ive seen on some forums in the USA that to help with keeping the F4i cool in hot weather, they change the thermo switch in the radiator to one from a nissan pulsar 1983 model... this is getting a bit hard to find so was thinking if anyone knows the thread size on the F4i, i can pick a thermo switch from another vehicle.. The aim of this is so the fan kicks in at 90-95c and not 109C ... was thinking about this one: https://www.aliexpress.com/i/32966167280.html

Anyone else put a switch in the rad that activates at a lower temp?
Cheers!

 

Awhile back I put in Duralast SW524 from autozone in my 01 f4i, its been working perfect fan kicks in around 214F now (stock kicked in at 225-230F for me if I rmbr correct) Not sure about thread size Ill try n see if I still have the old switch to measure
