    There's stuff called bars that you just add to the coolant. The blue devil says you need to flush the system and remove the t stat.

    heres my coolant flush procedure iv posted here 100 times lol


    remove the t stat, put the t stat housing back on, take the upper hose off the radiator, then push it down to the ground to a bucket or let it fly.


    get your garden hose out, put it in the rad turn it on, then fire up the car, let it run till clear water pumps out the top hose.


    then turn the hose off, run the car till no more water comes out the upper hose. then turn it off.


    put your t stat back in, with new gasket, the upper hose back on.






    now take 1 gallon of full strength green antifreeze, not the 50/50 crap. ( parts store cheap green is fine to use) dump the whole gallon in the radiator, fire up the car, fill the rad with hose water till its full. top as needed till its ready to be bled of air. it will burp and take coolant as the water in the block warms up the t stat opens up for a few seconds till cold coolant hits it and it shuts again.


    now to bleed the air out, let it idle rad cap off till the fans turn on, (when the fans are on the temp is over 195 deg, the t stat is wide open) then open the bleeder screw on top the t stat housing a few turns till a steady stream of coolant comes out the hole, shut the screw, top off the rad. cap it"

    if you have some clear thin tubing, you can put the tube down inside the rad then siphon it out to a gallon jug, then just put the new coolant in the rad and run it for while, then put the t stat back once its cooled off. then if you need to top it off, use the blue devil wwater you sucked out to top off.


    i used this stuff my self. my old 3800 would eat 2 cups of coolant. bd stopped the eating of coolant. but if you flush the coolant you will need to install more blue devil. mine started to eat coolant 5 years later when i did coolant change. had to add more BD.
