Radiator replacement / transmission cooler
This past weekend the radiator on the V6 sprung a leak. The leak has since been temporarily fixed, but still looking to replace the radiator in the future. The AC-Delco website lists three different radiator assembly part numbers, 21836, 92219558, and 92234040 which all show to fit the V6. Called their customer service department and the representative said the correct part number is 21836. However, search results using this part number yield a hose. Therefore, which of the above part numbers is correct regarding a radiator assembly on a 09 V6? Are there any good aftermarket alternatives available?
Secondly, the transmission cooler lines are connected to the bottom of the radiator in order to use the cooling capacity of the radiator to cool the transmission fluid. What options are available for a separate transmission cooler bypassing the radiator? I don't race nor track the vehicle, but would hate for the lower compartment to rupture and the antifreeze becomes contaminated with transmission fluid. On the other hand, it the chances of this happening are slim-to-none, then disregard the question.
Finally, how accurate is the transmission sump temperature reading displayed during engineering mode on the drivers information center (DIC)?
