Radiator fans

[BobE]

A quick question. When I was putting my recently acquired Tuscan away tonight the radiator fans started - or rather one did. Do they come on in sequence or should they both start together. I've had a quick look at the wiring diagram and there are two separate live feeds to the fans so depending upon the logic they could come on at differing temperatures or both together. Thanks in advance!

In sequence. One around 92 to 93 the other around 95 to 96.

Thanks Matt.

Matts correct.
Just want to clarify that if OS fan comes on as soon as you turn ignition 'ON' (but engine not running), it usually means that the trinary switch on the a/c system has failed...This assumes a/c is fitted ;-).
