Any benefit one has over the other...not sure which to get, and who's the best place to get it from, I got autozone, napa auto parts, and advance auto parts to choose from. Main manufatuers I'm seeing are Stant and CST.

Heres a pic of the pressure release type by cst autozone had a pic of

Would this be away to relieve any sort of air in the system from having the cap on and off..not really getting the whole purpose behind it, since I thought you were never suppose to take the cap off till car has cooled down :confused:

it safely vents the pressure through the overflow tube. i wouldnt use it as a method to bleed the air out of your system, its ment for cap removal when its hot so you dont get hit with a shot of hot cap and fluid.
