I think the red stuff your refering to is the "extended life" antifreeze. I wouldn't. It's usually more expensive, plus I don't think you can mix it with traditional green stuff.
i stick with the old green and change every two years. becareful around pets. and spills dilute real good with water. also i use distilled water as the mix. jim
Green only! Red/pink is dexcool, also another pink(rv antifreeze) do not mix them. Also, do not assume any antifreeze is nontoxic or safe to drink, rv stuff included. Remember what assume stands for !
Dexcool is the same color as the rv pink stuff, and is poisonos as hell. Be careful what you tell people!
ok well i drive 18 wheelers and they use the red antifreeze/coolant so i was wondering if the same stuff they use in the rigs would be ok to put in my 69' rivi.thanks everyone for your help
I talked to our truck mechanic and he stocks 7 different anti-freezes. And warns any mixing will cause serious damage to the gaskets and plastics of the diesel engines.
I like to use the enviorment safe green stuff, won't hurt animals n junk when spilled, as I spill everything so something should be eco safe. Make up for that rear main leak in that $185 pinto years back. Got 15gal jugs of used motoroil for free. After a yr or so you could follow the drip lines out my driveway to the places I went the most.
Stay away from that red Dexcool, (Deathcool) it'll raise hell with your rad, electrolytic reactions have been known to occur when that crud gets to a lower level and is exposed to too much air. (the pH changes and goes acidic) Your older Buick systems are not designed for this crap because there is no way to completely seal the system. There's currently a class action suit on this crap from disgruntled GM car owners with crudded up engines due to sludge and gasket failures. GM of course denies any problems... Use the green stuff, change it frequently and monitor the pH.
Any idea where I can get more info. on the class action suit? I've got a 2000 Regal that keeps making mud in the radiator. New radiator, hoses, water pump, and it still keeps making mud.:af:
Make sure you have ALL of the air out of the system. You will need to find the breather for your coolant system if there is one. Then crack that open while filling it until it overflows. Also start the car up let it get up to operating temp. (fans will cycle on and off) Crack the bleeder again carefully this time as it's nearly 200*. You will get some foam out. Once it comes out clear green or pink or whatever, your good to go.
Nate, I'll give this a try. Will purging the air keep it from making this muddy substance? I've had to replace the tube to the overflow tank twice because it was so stopped up with this muddy substance. 175 lbs of air wouldn't even clean it out. As far as the color if the coolant, it's a lovely shade of brown:rant:
I'm not sure the 2000 has a breather. I've read that it's caused by air in the system. It's supposed to be the cause of the mud. How about removing all the long life crap and using standard anti-freeze, that is less likely to turn to mud.
