Hello,

I'm looking for more info on cooling additives-water wetter, Penray Pencool 2000 and other additives- curious to hear any opinions and facts on what is used in motorsports, what voids warranty and if what comes in our cars is good enough-


I saw another magazine article on a product called Evans, but didn't get to read through-
Summer is here, temps get hot...

Best,

JB

I was looking into the Pencool 2000 after reading into what some others posted on here, but as the temps cool off back into the fall they told me I would have to drain and put coolant back in as the pencool could expand and crack the radiator? Don't know if this is true, but would love some more info on these products from those who have ran them as well.

Yes Pencool provides no freeze protection at all. Works fine year round in FL but otherwise YMMV.
