ACDelco Front Radiator Sealer 10-108 Black Metal 24CTN

Q: Will these work with the orange Dexcool antifreeze?

My mechanic said not to put anything into the anti-freeze. I will never use that orange stuff in my 1994 Cadillac 4.9 Deville. If you have the 4.6 North Star, that may be different story. GM tried to promote these tablets to cure a bad leaky North-Star motor. Jeff.

Q: Is this product preventative ?

Yes, this was actually put into aluminum block engines from the factory because of the porosity. It does an incredible job stopping leaks and preventing leaks.

Q: what is a ladder frame?

A ladder frame uses an additional block structure located between the cylinder block and oil pan, which incorporates the main bearing caps into a one piece component resembling a ladder, sometimes called a girdle.Feb 6, 2018
