What makes or what causes the internal coolers to leak. I ask this because i bought this product in Dec. An now i have transmission fluid in my coolant reservoir. I pray this didn't cause any damage to my transmission thats a costly fix?Ked D.Sep 09, 2021
Best Answer:Hi Ked, I'm pleased to assist you. The leak could be coming from the hoses or gaskets, still needs real-time diagnosis. Most of our radiators come with a 1-year warranty, in case it is the part that is defective if you bought it from our company. I searched using your email address but did not find an order history. We highly recommend having the vehicle diagnosed by a certified mechanic to determine what caused the leaking and what part/s need replacement to prevent further damage.

Radiator, 6.0L Engine, Plastic Tank, With Engine Oil Cooler, 34 In. Core
Amazing product
Works great, easy install also came with oil cooler lines in case I wanted to install them or had them. The stock radiator I took off didn’t have that option. Also one of the cheaper radiators out there.
