Just looked back at the pics on my phone and I don't see any install pics.

I do have a recently taken pic of the front end with the bumper cover off and you can see it. The bolts that came with the mount kit started rusting so I bought stainless steel bolts/washers/nylon nuts to replace them. They look crappy in these pics, they are the old rusty bolts with FluidFilm sprayed on them

That's the 19 row Derale model 51978 which is only like 6.5" tall. I thought about getting the 25 row model 52578 which is just under 2" taller but was afraid it might not fit under the plastic that surrounds the hood latch.

The mount tabs are seperate and they have a couple different styles.

The inlet/outlet on this cooler is 7/8-14 threads or -10an fitting. I found Dorman makes a fitting that screws in and accepts the OE style 3/8" snap lock trans lines.

EDIT: I used adapters to adapt the 7/8-14 threads to 3/8-18 threads to fit the dorman spring lock fittings. Only needed if using OE cooler lines. If using AN lines and fittings, then the appropriate fitting just needs to be used.

I know this is an older thread but wanting to do a cooler on my Tahoe and seen this “factory” looking one. Does this cooler perform a lot better than the factory one? And since you have installed the 19 row and see how it fits could I get by with the 25 row? I tow a camper and see temps around 215ish right now. Would like to stay 200 and under. Looking at the big tru cool but I like the look of this isn’t fits the OEM trans lines with your adapters. Thanks.
