PSP Diesel and Moroso Performance Products have produced a Ford 6.0L aluminum coolant reservoir bottle that is both highly functional and great looking. Made of 5052 aluminum, this reservoir is significantly stronger than those plastic OEM and aftermarket ones, which will eliminate the constant cracking, breakage, and subsequent leakage that most 6.0L owners are familiar with. The aluminum material also acts as a heat sink to keep your coolant temp down. The reservoir also features a 1/4" NPT port for a coolant pressure sensor to monitor the health of your EGR cooler and/or head gaskets. This is the last coolant reservoir you will buy for your 6.0L!
