STRATEGIC COOLING EXTINGUISHING EXCESSIVE EGT ON AN LBZ TOW-RIG

- 

Exhaust gas temperature is the single most vital parameter to monitor on any diesel. Whether your truck has been highly modified, treated to moderate power upgrades, or is completely stock, you always want to keep EGT as manageable as possible. When the owner of this ’07 Chevrolet Silverado 2500 HD—a truck equipped with an S300 turbo system, a built Allison 1000, and EFI Live tuning—saw 1,300 degrees F on the pyrometer while towing, he wanted to cool things off sooner rather than later. His urgency to shed EGT was amplified by the fact that the engine under the hood was an LBZ, the Duramax that’s (arguably) the most prone to cracking a piston due to added power and excessive heat.
