This kit addresses the factory coolant flow restriction in the cylinder head that allows hot, stagnant coolant to pool around the injector cups — the root cause of injector cup erosion, coolant contamination, and costly cylinder head repairs on the 6.7L Cummins.\u003c\/p\u003e\u003ch3\u003eWhy This Kit Is Essential for the 2013–2018 6.7L\u003c\/h3\u003e\u003cp\u003eThe 2013–2018 Ram 3500 6.7L Cummins is a workhorse engine, but its cylinder head coolant flow design leaves injector cups vulnerable to localized overheating. As coolant stagnates around the cups, corrosion accelerates and the cup sealing surface erodes. Once a cup fails, coolant enters the combustion chamber — leading to white smoke, misfires, hydrolocking, and a repair bill that dwarfs the cost of this kit. The Fleece coolant bypass kit keeps coolant moving continuously, dramatically extending injector cup and head gasket life.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCorrects factory coolant flow restriction specific to the 2013–2018 6.7L application\u003c\/li\u003e\n\u003cli\u003eEliminates hot spots and stagnant coolant around injector cups\u003c\/li\u003e\n\u003cli\u003eReduces injector cup erosion and failure risk\u003c\/li\u003e\n\u003cli\u003ePrevents coolant intrusion into the combustion chamber and fuel system\u003c\/li\u003e\n\u003cli\u003eComplete kit with all necessary hardware for installation\u003c\/li\u003e\n\u003cli\u003eFrom Fleece Performance — a trusted name in Cummins reliability upgrades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e2013–2018 Ram 3500 6.7L Cummins\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eHigh-mileage tow rigs and work trucks put enormous demands on the cooling system.
