I have had my 91 RR (140,000 K) for about 3 years. I have noticed lately the electric cooling fan comes on when I stop for traffic lights (outside temp. today was 58F), but will cut off when I start moving. The temp. gauge stays perfectly normal (about mid-way). The coolant is correct in the tank & I have absolutely no leaks. I pulled off the top radiator hose when I got home (after the fan began to run) & the coolant temp. was 160F. Oddly, I let the truck idle for 10 minutes before getting home and the fan did NOT come on, but it did come on later after only idling maybe 2 minutes. Any insight would be appreciated. I just know the electric fan did not come on last summer even idling! What temp. is the electric fan suppose to come on? I am not really familiar with the RR as I have owned Jags mostly.
