losing coolant after Mishimoto rad install

[Shoey2]

iv been noticing a steady loss of coolant over the months after my Mishimoto rad install. seems to be steamy coolant residue on the side of the rad under the cap. anyone one else here that can confirm my suspicions? if so who makes the best quality replacement?

Are you using the correct pressure cap for the system? Maybe its allowing it get too hot without relieving the pressure, etc to the overflow tank.

its the one that came with the rad, says its 1.3 bar. thats about 19 psi if my math is correct?

19 seems a bit high, but I'm not an expert in this area:

Greddy - 1.3kg/cm2 (18.5psi)

the mishimoto cap says 19 lbs on it. it just sees a little flimsy and chinese by comparison
