Review on 💨 Efficient Cooling Power: Denso 221-3109 Radiator for Optimal Performance by Eddie Simpkins

I chose this Denso radiator as an OEM so it was cheap. It was so easy to change. I spoke to the dealer to see what the difference is between the 3 models listed above. Her explanation was as follows. "TK" is the standard radiator (water and transmission cooler), while "T6" has an optional set of engine oil cooler tubes for the tow-pack Avalon. While some websites show TK6, they mean T6. My local dealer wanted $500 for TK and $580 for T6. Napa (lifetime warranty) and Bap (1 year warranty) were $40 more expensive than Revain when I called, and neither was Denso. I was happy with Revain's one year warranty at this price point.
