Why I have oil in the radioator

Hey reneeandgary – many have described this issue and found it's a blown head gasket. Other users might have additional information to help you out. Good luck! -KB

There are two oil-fluid coolers built into the radiator, one is for 'engine oil' cooling and the other is for automatic 'transmission fluid' cooling... If either of these internal coolers becomes reptured, then oil OR transmission fluid will be forced into the engine coolant during vehicle operation.. It is also possible for engine coolant to be forced back (back flow) into the failed oil/fluid cooler coil while vehicle is parked due to residual cooling system pressure.. This needs to be corrected ASAP as glycol (antifreeze) can seriously damage internal engine or transmission parts! .. The engine oil AND transmission fluid should be checked for antifreeze contamination as well .. Suggest clicking on > Find a Shop - feature on this page for a recommended repair shop in your zip code.
