Remove the heater hoses from the heater core at the firewall and hook them together. In order to connect to two same diameter hoses together, get a 5 or 6 inch piece of pipe which is the same diameter as the heater core tubes from which the hoses were removed. Install the pipe halfway into one hose and secure tightly with a worm-drive hose clamp. Then once secure, do the same with the other hose.j3h.
with your hands
Just unhook the hoses from the heater core and put a tube are something in the middle of them and clamp them together.
what are you bypassing

No , if you were to bypass the heater core , you would have no heat
Unfortunately, there is no "easy" way to change the heater core. The entire dash board has to come out. then it's easy. Then you have to put the dash back in. Sorry :(
This is just a guess so take it with a grain of salt. I would buy a belt for the s10 without air conditioning and just bypass the air conditioning pump.
