I am looking for a place where I can get this stuff analyzed to see exactly what it is and why it ended up in my radiator... this is the reason it has been overheating , at least that is what the dealer thinks...

 

looks like this place may do it but i would put it in a clean plastic container asap as to not contaminate it.http://www.imrtest.com/what_we_do/chemical_analysis/

 

Looks like some mexican on the line dropped his taco in the rad fill. I wonder if GM still uses those little tablets to seal the seams when they fill the rad on the production line. It could be the residue from them if they still use them.

 

bean taco

 

talked with them today.... $2000.00 estimate... can u believe that

 

what are they going to do for 2000.00? Looks time they buy it back!

 

could it be another victom of Dexcool?

 

find a university near you that has a mass spectrometer. they might be able to figure out what it is and to it for cheap. just ask for the chemistry department.

 

OUIT is a university here in Oshawa sponsored by GM Canada. It is a tech university, maybe a call to them would stir their interest.

 

I just sent the pictures along to my wife to get her opinion. To me it looks like either rubber chunks or an extreme case of oil/coolant mixture.
