Iam new to Altis. I noticed that i donot hear any fan noise but its needle remain at or just below middle even on long route i.e motorway. Today i ooened its hood, i saw there is one fan where as in Liana tjere were two. Well the needle was in middle but fan was not on. Then i switched on AC the fan went on. My questiin is why the fan was not on without AC. And if fan is not working how the needle remains in middle despite city and long route hard driving. Bit confused
