Stop in for a cup of coffee

My problem is I drive it 500 miles one way to work when the boat is working stateside. I have already blown the head gaskets once from an overheat due to a cooling fan failure. Torque to yield bolts and ARP was out of stock at the time.
That's a long drive with that smell and worry.
OTH GM used it to solve their warrenty problems on new cars!
