i have done the fan delete mod. i have not noticed an problems yet even in stop and go traffic on 31 degree celsius days. this mod allows the engine to rev up much more quickly. if you do decide to do this make sure to get the whole kit which includes a new lower temp switch for the electric fan and water wetter. with all that you should be good to go. if you ever do have any problms with over heating i have heard that it only takes about 15 min to put it back on.
