Just had my 99 SL2 serviced by my local mechanic who I have done business with for 20 years. Recently, I had the 60,000 mile service done by the Saturn dealer which included coolant flush and fill. My mechanic called me to let me know the PH of the coolant was near 12 which he said was not good for an AL engine. I called the Saturn dealer and no one there could tell me what the spec was for coolant PH, in fact, they said they never check it. Anyone know anything about what the PH should be ? They said if I can come up with any documentation they would "work with me"
