What hoses to bypass
Jus us a piece of usually half inch copper pipe n disconnect BOTH hoses from heater core and hook them both on each end of copper pipe or whatever u can find that will fit ID of heater hoses...plastic pipe is good too for this...heater core leak?...a good radiator sealer will fix this usually but you must have the heat on full for the solution can travel through the heater core...itmight still leak for awhile n then stop...if not, put some more radiator sealer in...always use the powered aluminum sealer...

SOURCE: heater core bypass
you will not have any heat at all ! so do this. remove the hoses. on firewall side to heater core. go to any auto parts store and buy a coolant flush kit, then use the right size tube to hook hoses back together and clamp them. recheck coolant and that should be it. good-day !

SOURCE: I was leaking anti freeze so I had a pressure test done. The Thermo bypass hose needs to be replaced.I have the part but I don't know how to install it. Does anyone know how to do this? Thanks
drain enough water out of the rad to get the level below the area you are working on, pull the hose clamps and remove the old bypass hose(if its older sometimes a box knife and a great tool to speed things up here) install the new hose and use new clamps, sometimes in a tight spot rubbing a little oil on the inside of the hose helps
