    If your confident in your flushing abilities, do it yourself, just remember after adding whatever coolant you go with, to open the bleeder on top of the T Stat housing and bleed the air out.

    flushing coolant is easy. take the t stat out, put the housing back on, leave the hose on the t stat housing, now take it off the upper rad, push it down to the ground.

    open the rad, put a hose in the rad, turn it on, then fire up the engine, all the coolant will pump out the upper hose to a bucket or the ground, as your filling the rad with fresh water, run it like this for a few minutes, usually till clear water comes out. then take the hose out, turn it off, then run the car till no more coolant comes out the upper hose, then turn the car off.

    put a new t stat back in hook up the hose to the rad, then dump 1 gallon of straight antifreeze in the rad, not the 50/50 crap. start the car, fill the rad with the hose.

    let the car idle, rad cap open till the fans come on, then open the bleeder screw on the t stat housing till a stream of coolant comes out. then shut it. top off the rad if need be, cap it, your done.

    waiting for the fans to come on lets you know the engine is hot enough for the t stat to open, some times you will see the rad level drop as well. that would be the time to bleed the air as well. because it opened and took coolant from the rad to fill the engine with more coolant.

    Score!! Looks like I'm going to be busy after work! Thanks so much you guys! Hopefully this fixes my 10 mpg! I'm at about 1/2 tank with a nut hair less than 100 miles.


    edit: Do I need to put lube on the new o-ring for the new tstat? Or just new o-ring new tsat slap it together?

    No lube (LOL) just put the rubber on the T Stat and make sure the mating surfaces are clean and dry, put the housing gasket on dry as well.
