You should spend the approx. $40.00 and 30 minutes of your time to get rid of that factory PS fluid cooler. All it can do is trash your cooling system when it starts to leak, and it will.
Other than that....as "flleetmgr" said.......sounds like you simply need a new cap. I've been using the Stant cap for the past 4 years with the pressure relief lever on it...$3.00 at PepBoys.
If that doesn't work....you very well may have a blown head gasket or some other pinhole leak somewhere thats letting air in after the engine is turned off and cools.
