I just bought a 2013 Volt (which I will pick up this afternoon). Since we are in the 5 year range does the car tell you when coolant change is necessary (like oil change) to keep 8 year warranty valid or do you just have to guess? I don't think the car is local and pretty sure the Honda Dealer I bought it from won't know where it was serviced. Can any Volt dealer tell where/what was serviced on it by punching the VIN into the system? Also while I'm here, the on line user manual says the wheel nut torque is 100 ft/lbs. which seems kind of high as my other cars are 80 - 85 ft/lbs range. Is this correct? I always have worked on my own cars but realize some of the work will be dealer specific especially while under warranty.
