Here is the story.... I bought a used 2008 highlander V6 Sports AWD few year ago and it came with a really rusty aftermarket Valley hitch and I replaced the rusty hitch right away with a new Westin one to tow my little boat (about 1500 #). Long story short, the boat got bigger and trip got longer so I ordered an transmission cooler to keep the fluid temp in check. I never bother to check if I have tow prep HL or not until today....in the process of routing the hose to new tranny cooler I spotted the factory cooler 😑. Do I have the tow package or not on my HL since it doesn't come with the factory hitch? I try to locate the oil cooler but can't really tell if there's one or not. My new tow weight is about 3000lb so I am thinking about returning the big cooler I got and order a small one to put it inline with the factory cooler. What do you guys think?
