One expansion tank is on the left side only. Which hose are you talking about in this case, there are two. (One in the back and one in the front that goes to the radiator) Note this is an old picture...the expansion tank to radiator hose that you see zip tied is hanging loose and occasionally will find it's way on top of the support which makes closing the hood difficult (Which I always notice and subsequently move the hose back where it belongs) If your clogged hose theory is correct then I should probably check this one first as it might have been pinched a few times.

I see you prefer trial and error by replacing parts rather than diagnose with test equipment?

Haha sometimes
at least I have several new ABS sensors
. I have some testing equipment but not everything.
