Looking for something today to help someone here,and ran across these....thinking early 90's.... Had a 50/50 mix,but lucky I had the rad cap off for some reason,and saved my a$$ big time. I saw/heard of a lot of cars go down from this one big time. Cracked blocks like i've never seen,and cars never to be seen again..... I was VERY lucky. This is for the WTF momments........
