Why did my 6.0L EGR Cooler Blow?
Ever wonder why your 6.0L EGR cooler blew?
This oil cooler half section shows an all too familiar sight. Its intended design is to cool oil (hence its name) by running coolant in passages along side the oil. However, the chemical nature of coolant creates sediment build up. This restricts the flow of coolant, making it nearly impossible to cool the oil, as well as reducing coolant flow to the EGR cooler. The hot exhaust flowing through the EGR cooler then causes the thin walls of the cooler to rupture, allowing coolant to escape into the exhaust and then be circulated into the intake.
Regular oil changes and coolant flushes are the best ways to prevent this kind of condition. If it’s too late, an upgraded high-flow Oil & EGR cooler can fix you up.
