Default Coolant Seeping by Thermostat Gasket (NOT CRACKED)

Aight guys. So last year at the end of summer, I was driving to Hooters and I saw coolant chilling on the ground wherever I stopped. Popped the hood when I got there, and sure enough the stock (Plastic crossover) intake was cracked. So the next day I went and got an AutoZone replacement (Dorman I think?). Installed just fine, but ever since I installed it I've had a tiny bit of seepage coming from where the thermostat and goosneck meet. Someone told me that it leaks because you cant have two aluminum parts coming together to seal a coolant passage? That seemed like a weird thing to say, but who knows. I think its probably just a gasket issue or something of the sort. Just wanted to get you guys opinions before I dig in. Thanks!

There is an O-ring seal in there that needs to be replaced. You do not have to drain the coolant, but do pack the area around the T-stat housing with towels (not good one), paper towels, or disposable diapers which work very well (I was lucky to have a stash for a visiting great-grandson when I last opened mine up).

When you remove the upper hose there will be some spillage but not a whole lot--tie the upper hose off so that its open end is higher than the radiator. There will also be some coolant loss when you pull the thermostat housing, but again not much...
