How exactly does it improve mpg’s?
And the UD truck I drive at work has a Nissan diesel motor and that truck is a huge POS. Something is always wrong with it.
Now its somehow losing coolant although its not even close to overheating and the overflow tank is full.
When the level of coolant gets low a highly annoying alarm sounds and a light comes on the dash.
This truck eats front tires, cooked a turbo and had a bunch of other shit go wrong and its an '08 with 76k.
