Detailed Description

Built as a parallel-flow automatic transmission oil cooler, the CSF 20016 is designed to route transmission fluid through a compact cooling core to help manage operating temperature in vehicles that rely on an external cooler. The core measures 1 inch thick with a 5 1/3 inch width and 9 3/4 inch length, making it a practical fit for space-conscious installations. This part cross-references BBB Industries 19018 and 19019 for the same application. It also cross-references OE-style numbers commonly associated with Toyota and Lexus cooling applications, including 3291060150 and 3292004010.

Compatible With 2005-2011 Toyota Tacoma, 2003-2009 Lexus GX470, and 2003-2009 Toyota 4Runner. Use CSF 20016 when replacing a transmission cooler on these vehicles and when matching the original tube-style connection layout.

Common Issues It Can Address

• Transmission fluid temperatures running higher than expected
• Reduced cooling performance from a damaged or restricted cooler
• Fluid leakage at the cooler assembly
• Cooling system service on a Tacoma, GX470, or 4Runner with an external transmission cooler
• Replacement of a worn OE-style automatic transmission oil cooler

Installation Notes and Tips

Verify core dimensions, inlet and outlet tube orientation, and available mounting space before installation. Confirm line routing and connection style against the original cooler on the vehicle. For best results, inspect transmission lines and surrounding cooling components for wear, contamination, or damage during service. Fits 2005-2011 Toyota Tacoma, 2003-2009 Lexus GX470, and 2003-2009 Toyota 4Runner, so confirm the exact model year before ordering CSF 20016.
