How to tell if the HEATER CORE is good or bad

[@greggkathy1892]

My heater coil was leaking coolant on passenger floor board

[@RBTheMechanic]

@@RBTheMechanic no live on georgia florida border don't really need a heater just connected the heater hoses together bypass coil.

[@thegoodinu]

So it seems they should both be the same temperature or close to the same temperature, or the heater core is not good

[@RBTheMechanic]

They should be close to each other and verify everything else works before ruling out core
