The cooling fan sometimes fails to operate. Temp guage sometimes moves to H. Suspect fan switch? Is this called the thermosensor which screws into bottom of radiator? Also, there is another sensor somewhere on the fan itself. My pdf prelude manual is useless as it has everything except the index. Which sensor is likeley to have failed.? Replacement radiator fitted recently and the system was refilled and bled correctly. It looks like you have to take the fan off first to get at the thermosensor on the radiator and disconnect top rad hose, to get fan well clear. Is it best to replace both sensors?

Would be grateful for any reliable information/best procedure.

Mikey

I think I've got it sorted now.Not a relay fault so must be fan switch. First time I have answered my own post!
