LLY Over Heating While Towing
#31
The video does clearly demonstrate that there is an overheating problem .. which is no big surprise as my uncle's '05 gmc lly overheats on a regular basis if its hooked to anything heavy. All I meant about this not being a scientific test is that if it had been me doing it I would have used another truck, like the stock 24 valve dodge, hooked to an identical trailer and load and then equip it with a camera and data logger. Its the whole concept of having a control to test against. Maybe its just because I'm doing graduate research and certain things have been drilled into me, but I still dont think it was a very scientific test.
Glad he won and that his business is doing very well .. someone needs to fix the 'excellent' designs they come up with in detroit.

See, the thing is, ya'll didn't see the other 4 hours of tape and it was scientific.
Here's what happened, since ya'll don't know the 3 1/2 years of crap that has gone on:
The '04.5 and '05 LLY was found to overheat under certain, but within GM's specs, conditions. While trying to find a cure for this (since GM was doing nothing about it) TxC took it apon himself to sue GM, not for a lemon law, but false advertising. TxC had blown a head gasket while towing, due to the overheating, GM drug their feet and claimed driver abuse. Once it all went infront of a judge, it was settled that GM would repair his truck (new engine) and garrentee it would not overheat. GM dicked around till the end of summer to get out of the 'hot weather' and gave him his truck back in late Sept or early Oct (can't remember which) '06 with a new engine and updates saying, 'try to overheat this...' TxC came up with a load well within GM weight specs, with a huge wind resistance to make it all happen. Some say puting a U-Haul on a trailer backwards was a 'setup', he tried front ways, but he couldn't get the axle weights to be correct, so he backed it on and all was well.
So he set off down I-10 from Houston headed west trying to overheat the truck while being fully within speed limits, weight,etc.... Well running the engine between 220-240*+ for 150 miles in 70-80* weather, Kerrville came up where the hills get real steep (for this area), that's where the guy in the Dodge ended up passing him while he was basicaly at full throttle trying to keep near the speed limit. The Dodge just happend to be at the right place at the right time for TxC and caught what it did on the tape. Here is TxC's own words: The "guy in the dodge" was a very elderly couple just cruising along, they had no idea that I was even chasing them. If I had to guess they were late 60's or early 70's in age, a man driving and a woman in the passenger seat. It was perfect that they came along right before the grades, and I had just put in a new tape in the camcorder too.
Once he hit the 'engine hot' and engine overheated' bells, then the truck went into 'limp mode' because of it, it was game, set and match. He had what he needed to go back to court and continue the lawsuit, because he indeed overheated the truck when GM said it wouldn't. The outcome was that he won. It was not easy and it didn't happen overnight. This was months in the making, a lot of time and money was spent proving his case for the outcome that he had.
He has all the 'science' needed. Weight slips, video and data reading of the databuss of the computer. A Dodge coming up at the right time was just the iceing on the cake....oh I'm sorry, it was the correct chemical makeup in the beaker to make up the ingrediance needed to make iceing for a cake....
kbailey, if your uncle wants to fix his truck and make it tow like the tow-hawse it realy is, I can easily PM you (since he is not a vendor here) TxC's website for the V2. Not only will it sqush the overheating, it will imporve his fuel milage, loaded or unloaded, by at least 1mpg.

I figured there was a lot more to the story than what you could see in the video.
My uncle farms a lot of ground so if he ever needs to haul anything they just put it on a semi now. Plus he trades trucks like every 3 years so he is due for a new one. If I decide to buy it off of him I'll probably get that information off of you, but for now the old 12 valve just keeps moving along.

I find it comical that those who dont own an LLY and havent had the misfortune of trying to pull a 13K load with it suddenly are experts on Christopher's proof of the trucks issue and the solution he came up with. Guess he'll just keep laughin to the bank as more and more people buy his kit. The free truck and $30K was kinda nice too.
My LiLLY has been pulled hard and it does not overheat.....let me repeat does not overheat. Some overheat and some don't...

I'm with SEA04DMAX, mine doesnt overheat either BUT there is a fix for those that do. Pick up a copy of Maxxtorque magazine summer edition. They have a huge write-up and fix. I might do it just to do it.

I cant remember the guys name, hell it may be TxChristopher for all I know, BUT it's basically replacing the stock LLY intake with a LBZ intake, buying a LBZ turbo mouthpiece and some other mods. There is a huge article about it. I will read it again when I get home. The author is a GM Tech and claims it fixes the overheating problem and dynos more power. He's not selling anything, just gives you the GM part #'s and instructions for doing the mod. I dont think Maxxtorque is on newsstands. I have a subscription. I'll read it again tonight and post what I can.
EDIT: I just flipped over to Dieselplace and read TxChristopher's RAD MOD. The fix in Maxxtorque is totally different and doesnt really mention the radiator at all.

The "Fix" in Maxxtorque is NOT a fix and has been proven to do absolutely nothing. That is the Killerbee theory that was proven not to work. He wont even sell the system to anyone on the West coast. BTW- All the mods done by GM starting with the LBZ where implemented by TXChristopher.
Let me reiterate: ALL LLY's WILL overheat. This has been proven more times than we care to keep discussing. You would think that after over 3 years of threads on this at DP everyone would get the picture.
