7/6/24 seems to work after engine is heated then cools down . Seeps into cracks?
Engine seems to be running smoother.  When first installed taken on 15 minute drive seemed to run rougher.
After cool down and topping off the water it seems to be not using as much water... didn't get as warm on drive home from grocery.
