Bhai honestly speaking, when i bought my liana in 2013 (2006 model) it was a pain for me as its fan was auto and it used to kick start based on a sensor. That sensor started giving issues and i could see my car overheating just because of a stupid fan not coming up at right time. Showed to so many electricians and issue was almost same. So i made it direct and its 2.5 years now and all ok.. Tstat pehle se nikla hua tha.
Cultus jo lee me ne, usme bhi tstat was already out and fan was direct. So i personally have no issues with this setup. Atleast car doesnt break down on road due to a stupid fan doesnt coming up or a tstat stuck in closed position.
