^^I agree. Check your oil as well. You will probably have to drain it as the antifreeze will probably be in the bottom. If there is coolant in the oil...make sure you drain it completely and flush it and change the oil often for a little while after fixing the oil cooler seals. If the rod or main bearings have been run with coolant in there for any length of time, you may need to change the bearings in the bottom of the engine as well. So catching it early is the key to avoiding costly repairs.
