Hey guys
Coolant lights been going, it was fine, but now i look in the coolant reservoir and its all brownish orange and gooey. Not good at all. Doesnt really overheat too bad at all though. Is this a blown head gasket? intake manifold gasket? somebody? anybody?

 

Its called Dexcool. It does that.

 

so this orange silly putty in my coolant reservoir is normal and wont hurt anything? i cant believe that...

 

Believe it or not, makes no diff to me.

 

I wouldnt say it wont hurt anything. Id change it out, but it is a characterstic of dexcool.

 

Blown headgasket generally makes the coolant overflow badly and the coolant gets a tan foamy creamy salad dressing consistency. Dexcool gets contaminated and starts to develop the sludge. If it's not overflowing, it probably just needs to be flushed and the collant replaced. The prestone flush kit is what GM recommends. Follow the directions, then replace the coolant. If you remain concerned about the headgasket, have it pressure tested bfore you do the flush.

 

dexcool will do this if its exposed to air.




just clean out your tank and refill it.

 

Thanks for all your help guys. Flushed out the system with water today, then i am running some Prestone radiator cleaner stuff for a couple days, before i refill with coolant. Still seems weird to me about the coolant. It was nasty. I had to use gas to clean out my reservoir, it was so bad. (dont worry, i rinsed very well) Anybody know where to dispose of used coolant?

 

*cough* storm drain *cough*


just kidding...


i think autozone takes used coolant just like oil...
