I had an oil cooler go out on my 2012 Dodge Grand caravan with a 3.6 V6 in it! It lost coolant immediately and the engine ran hot. Plus it mixed oil into the coolant system! I have purged the system the best I can! It smokes really bad now from over hearing. It blew a head gasket also! Will Bars leak work if there is any amount of oil left in the coolant system? Or will the oil prevent it from doing it's job to seal the head gasket leak?
