Not that I'm aware of...at least they didn't have. Don't know about the new models...

Sorry to all the loyal 7.3 guys, but I traded my '91 7.3 in on a 2002 F250 Ex cab V10 4x4. SCT Xcalibrator2 with tunes by Powerplay Performance. 285/75/16 Toyo M/T's. Took a long time to get used to the ping-pop of a cooling catalytic converter...LOL.

'85 Bronco swapped up to a 302 4bbl from the 300 I6, NP435 4spd, NP208, 32x11.50x15 Radial RVT's, Soon to be 6.9 turbo powered.

86 F350 Cab&Chassis with a dump bed. 2wd 6.9 and 4 spd tranny. No mods to engine.

2000 Volvo 660 N14 Cummins, 500hp 1650 ft lbs, Autoshift tranny 10spd.

What part of "SHALL NOT INFRINGE" do you NOT understand?

Not for normal operation,. However, if I remember correctly... in the event of a cooling failure, the Triton engines can disable half of their cylinders and go into a limp-home mode that supposedly won't overheat and damage the engine.
