I added that last year right before summer. Did you add the amount they advised or any extra? (and yes, I extracted same volume of fluid as I added).

But yesterday, driving slowly around a parking lot in circles trying to figure out what the short clanking sound is when I'm almost at full lock right, with full A/C blowing...I noticed I was heating up (and it was about 96 degrees) DOH!
Gauge got up to about 1/8 from top.
Wondered if I added a bit more RP antifreeze additive, if it would help....under the logic of "more is better"...
Temp dropped as soon as I drove on normally.
Thoughts?

p.s. I think one of my Kilby plates may be hitting/rubbing sumpin' at almost full lock right.
