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.

Thank You
The part was description and fit was spot on. The only concern I had is the box looked like it was in the battle of Falluga. So I hope there is no flaws that were unseen
