What PSI Cap Should I Use?

Last Updated: Aug 20, 2014 07:43PM EDT
The stock indicated pressure should always be used.  If you are going to play around with cap pressure, the goal is to get enough pressure to not boil over, while having low enough pressure to prevent the hoses from blowing off.  Most normal street vehicles use both 15 and 16 PSI caps. 
Check your owner manual or contact the dealership for more information on what PSI cap you may need.
