Hi All,
Starting to think of my last two driving months of this year and maintaining our 1952 Chevy 1/2 ton. My question concerns the necessity of changing antifreeze. I live in Michigan, drive 500 to 1000 miles each summer and use the traditional "green" antifreeze. The antifreeze still looks fresh with no floating particles or staining and checks out good for freeze protection. It has been in our truck for 7 years and from what I'm hearing I am past due for a change. Your opinions would be appreciated. Thank you.
