It is probably the toughest
thermal platform on the light/medium duty consumer use market! It will let you get away with a lot of poor choices, repeatedly. From a engineering testers perspective, I LOVE it.
There is only a small minority of people that combine the conditions necessary to overtask the cooling system. Cooling capacity is easy to fix for the few who want to pull other trucks around the planet, or any other commercial
use. I gratefully accept its limitations in deference to the failings of other similar platforms that can't hold a candle to this kind of thermal cycling abuse.
Anyone considering that this video shows the duramax in a bad light, I disagree, when i see it, I am seeing it at its very best
Any vehicle can be overheated, at any time of year, given the right combination of stress factors, beit artificially induced, naturally induced, or otherwise tampered with.
For those interested, I am developing (for 6 months now) an EFI tun that makes the overheat cycle impossible to replicate. It is not intended to replace cooling system expansion options, like the TD-EOC, but to give a 75-100 HP gain to a tow vehicle that also makes it immune to overheat.
The best part about it, is when it is released, it will be FREE
to TD-EOC users
This is just one of many improvements that I feel should encourage anyone who see's this thread and thinks: my pathetic truck has a "reduced value". Do not believe it. The DMAX is the best consumer grade diesel motor option in the marketplace, period, all things considered. That includes the LLY. Many of those that experienced this issue, no longer do. It is easy, and relatively inexpensive to fix. My fan and ECT gauge has been AWOL for a year now, that includes 90 summer days of 110 degree weather.
