Packaging:

Radiators may incur bent cooling fins or small imperfections during shipping or manufacturing. A few bent fins or small dents and scratches do not affect the fit or the function of the part.

Perfect Fit
This radiator was a exact fit for my 2002 Trailblazer with an I6. It came with the right fittings attached for the transmission lines. I am an at home DIY'er and recommend the instructional videos as they are very accurate, informative and well put together. Shipping was very prompt. This is not my first transaction with 1AAuto. I am always very pleased with the service and I will definitely be using for my future vehicle needs.

I installed the radiator no problems, everything is perfect except for the transmission lines. Fluid is leaking from the transmission lines connecting to the radiator. What is going on here, how do i fix this leak?

BEST ANSWER: I had the same problem with mine. Did you try to make sure the bolts were tight. Where the transmission lines come to the radiator. That's exactly what mine was leaking.. after I tighten them up it was fine
