So I knocked the hose off the bottom of the rad with a stick, leaked a bunch of coolant. Put it back on but the coolant doesn't seem to be circulating. Coolant temp is getting too hot, and fan is kicking in, but the coolant level in the reservoir isn't going down. Doesn't seem like it would be the thermostat because it was just working yesterday. Any ideas?

Thanks!

Edit: it's a 2018 not a 2015

 

Could be an airlock in the cooling system. Try running with cap off and look for lots of air bubbles.
