My daughter's 95 SLS with over 130k devoloped overheating problems.... I did everything but change the head gaskets....... I tried a product called "Blue Devil", I used half of the recommended amount and so far all seems to be okay...... She took the car on a 150 mile trip and no problems.... has anyone ever tried this product?:confused:

From their Q&A

Are there any applications where Blue Devil will not be effective?
Blue Devil should not be used to seal seam leaks in radiators and heater cores. It is also not recommended for Northstar engines.

Most likely cuz they know it wont work.
I know that they stand behind all 3 of their products
and most likely been down that N* road b4.

Well.... So Far This Product Is Holding True For Her 95 Sls...... I Have Read On Some Forums Where It Has Blocked Water Passages In The Block And It Was Hard To Remove..... But I Was Told That If Use As Directed It Works....... Coolant System Must Be Free Flowing
