Less then a quart +/- a week normal driving. If I pull a heavy load 2 or more quarts. I can smell the coolant sitting at a light then it goes away. This is a new motor with studded heads and a EGR delete. Theres no signs of any coolant trails any were on the motor I even die packed the coolant and used a black light, Nothing. Check the oil it's clean, trans. is clean too.
If I cant find this, I have to go back up to Bill and have him look for it.
Motor running cool not over heating.
