Follow your LOWER radiator hose. The housing that the hose meets is removed to reveal the thermostat.

follow where the top radiator hose leads too. it will lead to the thermostat housing, and the thermostat will be in there.

Wrong

But this is on a D16Y1, but is most likely identical on the D15B4

The problem you're having sounds completely unrelated to the thermostat.

The Mugen one will often open sooner and reduce operating temperatures. Something that isn't needed on a stock engine.

Yep!

After market thermostats that keep your engine cooler, by opening sooner, are more for racing applications where the engine is prone to ongoing heavy/hard use and will heat up over the regular operating temp

And for what it is, I think changing the thermostat is a real bitch of a job because I have big hands and the amount of working space you have in there is limited

Changing anything but the spark plugs is a bitch of a job, haha. Getting parts in the engine bay of a pre-EK civic/crx is like playing tetris.

Especially if you've got aircon and power steer.

Yeah I found this out when my family mechanic refused to do my thermostat back when I was noobier than I am now.

He's over 70 and has been a mech for 50 years but is a huge man with monster hands and was just like "No ****ing way am I doing that, everything Honda is a pain in the ass. You need a 1" screwdriver to get the first screw then a foot-long one for the next. You do it."

So he described it to me and what I thought was an easy looking job took me over two hours haha
