I have a 2000 Excursion with the 5.4L V8. The engine is a replacement with 10,000 miles and it has a new intake. All the other parts have 168,000 miles on them. When I am done driving I am getting an antifreeze odor most notable on the drivers side. There is no fluid leaking from the motor other than the condensation from running the AC. I am stumped trying to find the cause of this. Any help would be great.
