The only difference in the parts list that I could see for the cooling system (2019) was the lack of the "engine oil cooler" on 2.5L engine equipped models.
I believe that the 2nd hitch option is the one I mentioned earlier ( In Post #14) and is the "1,000 lb " towing option without the hitch guidance , etc.There is the trailering package on the website price&build, and then there's a 2nd hitch option on a later page
Well are going to be towing a 37 foot Cabin Cruiser or a 15 -20 foot bass boat. It's really hard to answer a question that gives no specifics! Obviously the Cabin Cruiser would be far heavier and your vehicle should really have a transmission oil cooler, HD Radiator, prewired trailer plug that uses relays fed by separate power wires, Class 4 or 5 Trailer Hitch, etc. as your Cruise probably has electric brakes on the trailer. The Bass Boat, no big deal, a Class 3 Hitch would probably suffice.Found an at4 for sale and its got everything except the tow package, allegedly. Havent seen in person. Do i dare tow a boat without the "trailering package"? Is it as simple as adding an extra cooler? Does it change out the rad itself?
Your sister's Blazer is not your Acadia. You are comparing an apple to an orange.Now....salesman said that tow package adds an extra cooler without changing "normal" rad.
I don't want the normal rad because I've heard of multiple issues and sister's blazer rad only made it 12 months.
Blazer and Acadia also share the same C1XX (Chi) platform, along with the Enclave, Traverse, XT5, and XT6. Given that, the comparison is more like one variety of apple to another. A lot of parts are interchangeable.While you are correct, the blazer is not an Acadia... it IS the same radiator
