All the power and energy generated when you amp up your Sierra’s engine for extra horsepower and torque turns it into a useful, exciting powerhouse, but it also generates surplus heat – which you can manage with aftermarket 2014-2017 radiators, intercoolers, & accessories. AmericanTrucks sells everything you need to cool down your overheated pickup and keep it roaring away for hours problem-free, including 1999-2013 accessories like performance thermostats or intercooler pipe kits that feature mandrel-bent tubes to increase cooling effectiveness by up to +200% over stock. Companies like Mishimoto build 2014-2017 intercoolers that greatly increase cooling efficiency with oversized internal fins and lightweight, heat-shedding aluminum construction. Racing grade aftermarket 2014-2017 radiators further amp up the cooling process – keeping your engine from overheating, and preventing oil from thinning and causing oil starvation.
