My 2007 Outlander comes with the factory towing package, (which is news to me in my 8th year of ownership, as indicated by the VIN), and I'm wondering if anyone knows the differences this package adds? I need a new radiator, and the part listed for my model is not the part listed everywhere online. The only one I can find online is the one most people seem to have: 1350A050, and noted by most sellers as w/out towing package. Well, mine is 1350A490, and I can't find it anywhere but the dealer suppliers for $730-ish. I have no idea what the difference in the radiators could be, and I'm hoping the shop I take it to can modify it to fit. They all use the same hoses, so how different can they be? The diagrams of the radiators look the same as well. Anyone know these two parts' differences? Capacity only? If that's the case, I definitely don't care. Have never towed anything with it.
