    So im finishing my overhaul job soon, and i have started mounting cooling.

    The stupid thing i did, i didnt take Pictures and i threw all broken hoses and parts, - this was 2 years ago.

    Now i dont even cant remember if i ever had a heater valve.

    This is a 1982 Dodge Omni 024, 2.2 carbed.

    I noticed that rock auto sells one for 1982, but i cant see how this witl fit, as my waterpump only has one outlet -for the radiator.

    Normally, coolant always circulates through the heater core. The temperature blend air door chooses hot, cold or mixed air.
    An exception would be A/C cars where a water valve shuts off heater core coolant flow in the MAX A/C position only.

    It isn't particularly necessary in temperate climates.

    Don't have a SM, but if you have AC you should some type of shut off valave. Non-AC equipped cars didn't have one as far as I can remember back then.

    So i know you have Daytonas Bob, and so do i.

    I have deleted A/C on my turbo Z. Do you think i could delete the heater valve -just to prevent water leaks an clean up engine bay?

    Absolutely. The heater valve was only to block coolant flow through the heater core for air-conditioned cars, so that the A/C would not have to work as hard in the maximum setting.

    If you have heat coming into the passenger compartment when you don't want to and do not want to pull the dash to fix it you can add a manual heater control valve. On my 86 Omni Glhs I wanted a larger radiator but didnt want to cut her up to do so ,so I rigged up a heater core from another car up front and routed the lines from the heater core to the new up front heater core with a manual heater control valve.
