hey guys ive got 2010 fg xr6t, only got 700 on the clock. so when im crusing up the expressway at 100, there seems to be a whining sound coming from the engine (by the sound of it). its only happens around 100, sit on 105 or 95 and there is nothing. also just wondering where the temperture gauge normal sits at? around half way?? any feed back would be great cheers
