What happens here

With the coolant drained, proceed to remove the old thermostat. This involves tackling a hose clamp and two bolts. The hose clamp is often difficult to access. Use hose clamp pliers (straight or angled depending on access) to release the clamp and slide it back on the hose. Next, remove the two bolts securing the thermostat housing. The video suggests using a 10mm socket wrench or, if preferred, a T25 bit, as the bolts have both hex and Torx heads. Carefully pry the old thermostat housing free from the engine block, being prepared for any residual coolant to spill. Wipe away any excess coolant from the engine block to ensure a clean mating surface for the new thermostat.

Goal: Detach and remove the existing thermostat housing from the engine.

Now, I'm going to grab a Put those where you're going to lose them. So, instead of a star bit, I ended up just using a 10 mm socket to get in there cuz the it's Yeah, it's got T-25 on the inside. Nice. This is the real [ __ ] guys. So, I end up just using a 10 mil to get in there. So, I'll find that in a bit. This is our old old thermostat.
