i am also getting my khyber 98 model to setup on auto fan ,,, i got the new flange, new thermostat valve and new temperature sensor (temp sending unit) .... but now when the mechanic installed it, he claims that sensor and flange does not meet the size of thermostat ... he installed the flange and sensor and still the fan is working on auto but he is asking me to arrange different size thermostat valve as he claims that the flange size is smaller.... i got my parts from Arafat autos - Plaza
secondly you have mentioned about the button in dashboard that allows to get the fan t be direct when required ... where r u getting it done, i would like the same facility to be installed
