i got a 1999 f350 7.3 powerstroke with oil in the coolant im going to replace the cooler this weekend and need to know about flushing the coolant system of oil. Anyone got any write ups or how to's?

 

Use soap with degreaser in it like dawn with water only run truck until hot if u carefully open coolant cap to let pressure off oil will boil out don't take cap off completely have something under res.bucket to catch oil let cool and repeat until most oil is out drain out water and fill with coolant also think about getting new res.bucket very hard to clean out after market buckets not bad for price
