Hello Everyone, first time poster here! I've looked all over the forums and can't find the answer to the question I have, and I'm hoping yall could help! I have an 09 2.4L camry and the radiator just busted. When I look online for OEM radiators to replace it, I'm given 3 options: part number: 164000H310: towing package (I don't have the towing package, so this isn't the radiator I need) 164000H210: $294 16410AZ024: $115 For the life of me I cannot figure out the difference between the expensive one and the cheap one. They appear to be identical, which is the direct replacement for my radiator? has anyone run into this before? Thanks guys!
