My heater core is bad; I bypassed the core by joining the 2 coolant lines it is supplies by with a copper barbed fitting.

While in the yard I noticed that the 92's and 94's had eliminated the valve and that the coolant lines go directly from the heater core to their prospective components. Can I do this on the 90? Will it produce any sided effects. Will my computer need a pack of menthol 120's?

Ulitmately, I had never seen such a valve in an automotive heating system before and it seemed simpler to me to just eliminate it. I am not an electrical engineer or heating/air conditioning expert...I just want to simplify maintenance whenever possible.

All thoughts are welcome as I am installing the new core, I do have the valve too, I just don't understand its purpose or the merit/deficite to using or not using it.
