    Are all the fan speeds working and did you lose any coolant (repairs, leeks, etc)

    Check temp at tstat if you have temp gun. Also check heater hoses if one if more off then other maybe a pluged heater core. Both easy fix. Nedd more info just let me know.

    Just recently had the plenum gasket changed, they were supposed to put a new thermostat in. I havent had any coolant loss, The fan speeds are all working, just blowing cold. I did check the hoses leading to the heater core, the passenger side was really hot and the drivers side was warm. Any more questions just ask I would really like to have this fixed soon because they are talking snow by tuesday night. Thanks in advanced.

    Does the engine temp read about normal on the gauge?

    You say you haven't experienced any coolant loss, but have you actually looked in the radiator or overflow bottle to confirm that it is full?

    360 engine I'm assuming?

    I would try flushing the heater core then they should be equal.

    Coolant level is full and the temp is a little lower then what it used to be before the repair.

    My advice would also be to try flushing the heater core.

    That's good then. I'd start with the thermostat. If they just changed it, could be wrong temp, or just lazy.

    Alright thanks guys I think i will try flushing the heater core and changing the thermostat. I checked the paper work and they put a 180degree thermostat and it says you need the 192, dont know how big of a difference that will make.

    About 12 degrees.. :)

    Seriously though, it should have a 192 to run correctly. And you'd be surprised the difference it could make in how warm your heat is.

    Had this problem last year. Was told is is common for older Dodges for some reason it gets a brown gunk like substance in the system. remove heater hoses and take a hose and clean out the heater core. May want to flush the radiator and use new coolant when done. Took care of the problem on mine and have heard others try the same method with good results.

    just flush the whole system it costs like $70-90 at almost any dealer and if they do it right you can see all this like light brown crap come out then replace the thermostat

    and ford guy lol i had a 1997 f-150 that needed a heater core cost more than the truck was worth to have some one fix it and i didnt wanna mess with it lots of work trying to get that dash out and back in right with out messing any thing up or having coolent all inside your truck
