One of the fleet vans (2005 cargo) had the oil cooler pop and now I have oil in the radiator and all the hoses are soft. We were lucky enough not to get water in the crankcase, but what is the best thing to use to flush out the cooling system? When I worked on marine diesels we use dishwashing detergent to coagulate the oil then dump it out but I'm not sure if that would just clog up the system in the sprinter. Thanks in advance for any advice and suggestions!!!
