Overheating 6.0 Ford Power Stroke NOT blown head gaskets Bullet proofed HHG HD

A buddy of mine with 6.0 issues...go figure. A local shop didnt bother to diag it and just said it had blown head gaskets. Further diag showed it had multiple issues and a head gasket wasnt one of them. Back on the road and the cab never had to come off! I actually really like working in 6.0 Power Strokes
