    engine bay and the temp went straight down to normal operating.

    Today I tried to let it idle outside for 15 min or so, (no fan) but since the temp outside is -1 degrees I think the wind blowing into
    the engine bay is keeping it cool. So again it remained at operating temps and the fan never kicked in automatically.

    I didnt check the coolant level after todays run, will do that in the morning.

    Thank you
    Are you talking about engine fan or cab heater fan?

    I think it was the cab heater fan, since that is for the blower.thanks

    You're cab heater/blower fan for the inside of the car will not cause your car to overheat. Anytime someone has mentioned "fan" in this particular thread they are referring to the engine/radiator fan. You might want to go back and re-read all the posts as I think you may be slightly confused.

    Well, if the relays for the engine fan are both good, there is another sensor in the motor that kicks on the relays based on the engine temp.

    That seems it would be a lot in terms of labor...

    Would it be a coolant temp sensor ?

    Just need to get this sorted out by April, just before hot weather and wedding season.

    Again no change in the coolant reservoir.

    Thank you

    Yes and Yes. Before tearing into getting at that, I would go through the test I had above and see if you have power at the relays at the different temperatures that each relay is supposed to kick on at and then test to see if you have power at the fan at each stage. This will at least eliminate if the problem is between the coolant temp sensor and the relays or between the relays and the fan.

    Alright, so turned out I had intermittent parts that were about to fail. That made it slightly harder to test, but thanks to all your help
    it has been solved.

    - Replaced thermostat
    - Replaced radiator fan (the motor was not blowing fast enough at high temperature but was coming on)
    - replaced relays at same time

    Still need to replace the old intake with the new aluminum style.

    So far so good...

Auto Zone sells the intake with gaskets for about $250 and it takes about 3 to 4 hours to replace.
    After being through the school of hard knocks with this very issue, I can definitely say you are so very right about this. With 6 LTC's, I now keep a manifold in stock ready to go. I am also considering proactively replacing the ones I have that haven't been replaced yet. Like Mike says here, its a lot cheaper to do it on your own terms rather than on the car's terms... which at least in my experience is usually the morning of when its scheduled to make you $1,000.

    ^^^

    Yea I was glad to finally solve the problem. Did not loose any bookings.

    If anyone ever gets the following codes: P0230 and P0231 come up, replacing the relay may solve your problem.

    As for the intake manifold, I will get that done asap, as you guys have mentioned it is best to do preventative maintenance especially
    on a sure problem. Next week till end of June am booked every single week...

    Thanks
