OIL IN COOLANT. Defective oil cooler, it's part of the radiator! Any coolant in oil?

Oil and trans. coolers can be tested to confirm. Get your mechanic to check it for you.

Thanks. I installed a new radiator before I noticed the oil in the coolant. I will get radiator checked. Is there anything else that could be the cause?
