thanks,

I wouldn't do any of this. I would complain to the dealer. Something is not right here, and may not be right with an entire block of production. It could be the fan clutch, the radiators, fan pitch, etc. The H3s should not be getting this hot. You're not even towing a trailer! GM has higher standards than this, so either engineering screwed up, or the supplier is providing parts which are out of spec. You should be able to tow a fully laden trailer (3500 lbs with manual, 4500 lbs. with auto), up a grade (such as the eastbound 15 Baker grade in California) at 100F with the A/C on full at the speed limit (or as fast as the truck will go). If it can't do that, there is something wrong.
