Connection of the coolant feed line is made at the passenger side heater core hose located above the valve cover. Routing the new hose around past the oil fill spout, you can make this connection much like the return hose. Just cut and splice into the factory hose, making sure to use the supplied hose clamps to ensure no leaks will form once the coolant is refilled and the system is pressurized.
With the cooling system connections completed, it was time to move onto the oil filtration side of things. The 6.0L Power Stroke oil filter can be found right on top of the engine, under the large cap pictured here on the left. The smaller cap on the right houses one of two onboard fuel filters. These caps are made of a high-impact plastic, but are prone to cracking and splitting due to the extreme under-hood and engine temperatures they endure on a daily basis. This is also something Sinister Diesel will resolve with parts found in the Oil and Coolant Filtration kit.
