86 Coupe DeVille
Ive read about these pellets that Cadillac 4.1s are supposed to have added into the coolant. I went into ABC auto and told the woman what i was lookin for and she slapped these down on the counter. Is this the correct thing? i went ahead and got em since they are only 3 bucks but they just look kinda big. If they are the right kind should i put them all in there at once?
