This only happens on the '04.5 and '05 LLY. The '06 LLY, LBZ and LMM all have corrections to them to keep them from overheating. *Some* LBZ guys can still make their trucks hotter than wanted and have added the V2 to keep their truck's temps in check.

Most will never pull a load big enough to make their's overheat, but the one's that do cry like a baby when they see those temps rise uncontrolably esspecially when they swore up and down their's did not overheat.

 

Well all I know is my old skool 12V will pull a 20K lb trailer all day long and the clutch fan is only on maybe 25% of the time, and it still doesn't get too hot. If I'm in stop and go traffic the fan has to run 100% of the time to keep things cool, but thats typical for towing heavy in traffic. My buddy tried to sell me on an '05 at the time, glad I never considered it.

 

It's funny, overheating LLYs are coming out of the woodwork right now, with a the sentence- 'I just bought this used truck and hooked it up to my trailer......it overheats'.

If you would of bought his and had a problem, the V2 will squish it. I very rarely hear my fan anymore, much less see the guage move.

 

Is it a timing box? Boost fooler? What does it do to keep the engine so much cooler?

might have been said, but I just love the way he just lounged out in the hammer lane, and folks wonder why they get passed on the right.......... he deserves that truck. the whole vid, what, 20 minutes? he was there the entire time, what a maroon.
