The 13 psi cap will raise the pressure in the system to 13 psi vs the 10 psi with the 10 psi cap.
A pro would be that under more pressure the boiling point of water is raised.
i bought a 13 lb cap and added "Water Wetter" to my system (http://www.redlineoil.com/products_coolant.asp?productID=53)
tomorrow is supposed to be 95 degrees and im goin to a car show, so im gonna see how this works. if im still not satisified, a new radiator is going to be purchased.

My brother and I both use Water Wetter and have been satisfied with it. I have an electric fan that comes on around 185 and before Water Wetter the fan would always stay running once it turned on, on a hot day while at idle. Now the fan cycles on and off like its supposed to because it can cool better.
i also have a electric fan, but it stays on. its wired in where when the key is on, its on. i will prolly change that when summer gets over with. what temperature differences did you see? how many bottles did you use? i have a friend with a built stang and he uses 5 bottles of this stuff.

your friend is wasting money one bottle is enought for a basic cooling system.5 12 oz. bottles will treat 760 quarts.Cobain03 said:
