Hi

trying to understand the heater hoses and where they start? I’ve seen pictures where
Both hoses connect to the bottom of the expansion tank? How and if so couldn’t I just cap off that bottom of the tank instead of bypassing the heater core with a hose to hose connection?

Yes you could do that. Why do you want to bypass the heater core though?

Since you need the special connectors that are in the the heater hoses, I would cut those and splice together with a pipe inside and hose clamps.
