This radiator works like it should! It wasn't super expensive and it fits where the old one used to be; and it's holding really well so far!

Question: The transmission coolant inlets have internal (female) and external (male) threads.
What type/size thread is the male?Skyler J. / Jul 11, 2022 / 2003 Chevrolet ImpalaRadiator, 3.1L/3.4L/3.8L Engines, Aluminum Core, Plastic Tank
Hi Sky, I'm glad to assist you. That specific dimension data is not noted anymore since this is a direct fit vehicle-specific part. Just by entering the year, make, model, submodel, and engine size, the guaranteed-to-fit badge (a round green circle with a white checkmark) would show up and confirm 100% fitment. Please tell us your vehicle application so we could confirm fitment. I hope this helps.

Question: Does it come with a tank?Beverly A. / Aug 05, 2021 / 2003 Chevrolet ImpalaRadiator, 3.1L/3.4L/3.8L Engines, Aluminum Core, Plastic Tank
Hi Beverly, I'm pleased to assist you. No. This is just for the radiator itself. The coolant reservoir (tank) is sold separately. Click on the link below to order at 45% off the regular price while supplies last. I hope this is helpful.
